There are several methods to measure how much light is intercepted by a canopy in order to determine if water loss is from evaporation or transpiration. Theres the hard & expensive way and then theres the smart way: the CTR-1. Virtual make Ceptometer offers convenient and flexible tools for measuring and analyzing incident and transmitted Photo synthetically Active Radiation (PAR) in Crop and Forest canopies. This is a a non-destructive method to easily and accurately measure Leaf Area Index (LAI). It provides vital information about the penetration of PAR into crops and forest, and is essential in work such as comparative crop studies, for separating out the effects of cultivars and treatment. It is particularly well suited to low regular canopies (as found in many agricultural crops). It can be used in most light conditions. The first sensor probe has an array of 10 PAR sensors embedded in a 1m long probe, and is connected with Handheld Terminal. The second sensor probe also has a 1 PAR sensor embedded in a 0.5m long probe, and is connected with handheld Data logger. One PAR Sensor is also connected with data logger for reference incoming radiation. When a reading is taken, all sensors are scanned and the measurements transmitted to the data logger. The average light level along the probe is calculated. Further you can download data from data logger to a computer (USB Port) with the help of "Virtualware" (PC Interface Software).

this ccf sensor is for measurement of the cloud cover factor. This innovation of dr. Sten lofveng makes it possible to get automatic observations of the cloud cover factor, ccf 24 hours a day i.e. The fraction of the sky that is covered with clouds. It consists of a day time unit that observes the sky in 4 directions in parts of the solar spectrum, a night time unit that observes the sky in the thermal infra-red spectrum. A microcomputer evaluates the signals and controls the output.

Instructions for replacement of the reed switch assembly

1. Loosen the 4 Phillips head screws at the base of the collection bucket.

2. Twist the collection bucket counter-clockwise and remove it from the base.

3. Observe the tipper assembly and note the two axle supports holding it in position.

4. On top of each axle support is an eccentric washer with a screw holding it in

place. Loosen and remove the washer on each support.

5. Remove the tipper assembly (tipper, axle and brass eyelets) being careful not to

loose the eyelets.

6. Observe and remove the switch assembly by loosening the Phillips screw.

7. Cut the two wires on the existing switch assembly at the circuit board leaving

approximately two inches of each wire exposed on the base.

8. Place the new switch assembly in the same manor and position as the former

assembly. Screw it into the base.

9. Strip the insulation from the wire ends and use the provided wire nuts to complete

the switch replacement.

10. Replace the tipper assembly and eccentric washers.

11. The washers can be turned in conjunction to position the tipper with respect to the

switch. The contact between each washer and eyelet allows for this positioning.

Ideally, the distance between the magnet and switch should be between and 1/8

of an inch.

12. Once the position of the tipper is established, tighten the eccentric washers. There

should be some movement of the tipper on the axle, approximately 1/32 of an

inch.

13. Verify proper operation by replacing the collection bucket back on the base and

pouring a small amount of water through the collector to facilitate tipping of the

assembly. You will hear it tip. Each tip should account for a 1/100 inch

increment on the counter or display.

Installation and Operation

of the Rainew Tipping

Bucket Rain Gauge

The Rainew Tipping bucket rain gauge by RainWise

is the culmination of over thirty years of experience as

the largest manufacturer of rain gauges in the world.

Follow these easy instructions and you will experience

years of trouble-free operation and enjoyment from your

rain gauge.

1. The following items should be included in the

shipping box:

* The Rain Gauge

* Connecting Cable (this cable can not be buried)

* The Display

2. Determine a location for the Rain Gauge keeping in mind the following guidelines:

a. Choose a flat, level surface at least one foot above the ground.

b. Make sure the area is open with no overhanging

obstructions.

c. Avoid mounting the gauge on a steel or iron surface.

d. Locate the display inside.

3. Back out the four (4) screws holding the collector onto the base until it can be rotated to a point

where the collector can be removed from the base. Remove the collector. Using the four (4)

screws supplied with the gauge, mount the base at the location you determined in Step 2. Do not

replace the collector.

4. Run the wire from the gauge to the location of the display. You can run the wire through a window

if you are careful not to cut the wire when the window is closed. The cable can not be buried.

5. Plug the connector on the cable into the receptacle in the counter.

6. Move the dipper in the bottom of the Rain Gauge base back and forth. You should see a count on

the display for every tip of the bucket (0.01 per tip). Zero the counter.

7. Place the Rain Gauge collector back onto the base, rotating the collector until the ears are fully

under the screw heads. Tighten the screws until they are snug (Do not over tighten). This

completes the installation.

NOTE: a) The counter is powered by an alkaline button battery # 357 and should last at least a year.

To change the battery, you will need to locate a one inch slot on either side of the back. If you look

into the slot , you will see a pressure tab. Using a small flat blade screw driver, place the end of the

screwdriver between the edge of the case and the tab. Slightly twist. The case should separate. The

battery is located in the silver clip. It will slide out either from the top or bottom. A replacement battery

may be obtained at most drug or hardware stores. b) If your collector becomes obstructed and

you remove the cotter pin to clean the rain inlet, please remember to bend the legs back up out

of the way, when reinstalling, so that it doesnt interfere with the tipping bucket.

Warranty Information:

Our rain gauges have a lifetime warranty on the gauge. The electronics (counters and switches) are

guaranteed for one year. There is also a $15.00 shipping and handling charge on repairs. Please

enclose a brief note, daytime phone number and current shipping address when returning a rain

gauge for repair. We will call with your repair cost.

Compact, robust, flexible - the new UnilogLight is a versatile

service-wonder within the SEBA Universal Logger family. As an

economic and all-purpose data logging system, the Unilog-

Light is suitable for a large scope of applications in the fied of

hydrology and meteorology

The IRIDIUM satellite communication system currently

consists of 66 active satellites enabling a world-wide data

transmission by means of low earth orbits, LEO. The availability

of data is thus ensured at any time and without time slot

reservation

DEMASdb is a graphical database interface that was specifically

designed for the collection, storage and management of

measurement data. The application is suitable for both large

and small monitoring networks. DEMASdb channels and imports

the incoming measurement data manually or automatically,

introducing them in the Paradox database and thus

keeping everything in order. Alternatively, DEMASdb can

also be connected to the existing SQL databases (e.g. Oracle,

MySQL). DEMASdb is also multi-user, so that multiple users can

simultaneously access the data. Thus, it is always ensured that

all data remains consistent. Limitations are imposed on the

partially or fully unauthorised users by means of configurable

user rights (option). The export function of DEMASdb allows

for the time series to be converted to different file formats

and then to be passed on to third parties. With the evaluation

software contained in DEMASdb DEMASvis the archived time

series can be displayed in the clear form of charts and tables by

clicking on the measuring points Explorer

DEMASole is the expansion module of DEMASdb serving for

online call of measuring values. It controls measuring systems

that are equipped with data transmission e.g. a modem. The data

collection online is effected automatically. In combination with

DEMASdb, data transmissions are started directly using the user

interface of DEMASdb. DEMASole is also available as a stand-alone

version and thus enables the integration into existing process control

systems.

DEMASole is divided into two components:

The so-called call module and the configuration module. Using

the configuration module, online measuring stations with their

respective access parameters (request job, type of connection) are

set up. The configuration file can be exported in *.XML format for

further use on other PCs via authorized online access, without any

further modifications. The call module is effected on a computer

with access to the hardware resources (telephone modem etc.).

DEMASvis is a comfortable, windows-based software for visualisation

and analysis of time series. The simultaneous display of

graphs and lists guarantees optimum clarity. Numerous features

(including zoom, transition curve correction, control value input,

block diagrams) and calculation features facilitate working with

both measurement data from SEBA loggers as well as from other

sources or storage media. With the practical Live Mode, the users

of SEBA cable electric contact gauge KLL-Q-2 the ability to automatically

send the current readings as push data, and to visualise

in both tabular and graphical form and save them with DEMASvis,

for instance, on the field-fit HDA-Pro .

DEMASvis is available as an independently running program

with a single workstation license. However, the evaluation software

also constitutes an integral part of DEMASdb (data capture

management evaluation software) and with limited functionality as a

visualisation program ConfigPC

The DischargeApp is a low-cost, user-friendly smartphone

application which provides fast and accurate discharge

measurements in rivers and open channels. It is only needed

to have four ground control points on the field, no expensive

equipment is left at the place. Additionally, the cross-section

of the water body needs to be measured. Depending on the

size and complexity of the channel, the initial site setup may

take between 15 minutes and 1 hour, but his has to be done

only once.

Measuring the discharge on a dedicated DischargeApp site

takes less than a minute. The computation occurs locally on

the smartphone, hence the DischargeApp can be used to

measure in regions without network coverage. Once the

measurement is done, data transmission to the cloud is possible

immediately or later, as soon as internet is available. This

allows error-free data transmission and storage. The measurements

can be accessed via the integrated DischargeDataHub

platform. On this platform measurement data, sites, users and

user permissions can be managed. Access to the data is secure

and login protected

The DischargeKeeper is an innovative product for the continuous

measurement and storage of water level, surface velocity

and discharge in rivers, irrigation furrows and wastewater

channels.

The DischargeKeeper consists of an IP-camera, an infrared

beamer as well as processing and transmission units. This

non-intrusive measurement system can be mounted on

existing structures in a versatile way.

The SEBA-Electric Contact Meter type KLL is a portable, reliable

instrument for measuring the water level and total depth in

boreholes, wells, reservoirs etc.

For the measurement the probe is lowered to the water level.

When touching the level, a sensor effects the illumination of a

signal lamp. On request, an additional acoustic signal will be

released by a buzzer. The depth is shown on the cable in metres

and centimetres. If the measurement of water level and

total depth is desired, an additional ground sensor (see accessories)

is adaptable. When the sensor is touching the bottom,

the signal lamp is switched off. In case of very small diameter

tubes, instrumentes with a probe of 10 mm dia. (not suitable

for ground-sensor and sensor-cap) are available

The new SEBA-Electric Contact Meter type KLL-Light is a

portable, reliable instrument for measuring water level and total

depth in boreholes, wells, reservoirs etc. It especially stands

out for its fast and reliable data logging.

The cable drum of the KLL-Light is made of lightweight, shock

resistant polycarbonate, which is perfectly suited for field use

due to its solidity. The corrosion resistant probe is connected

via an anticorrosive polyethylene cable with two steel cores to

the battery-powered signal unit in the cable drum.

The KLL-Light Electric Contact Meter is equipped with an

acoustic signal as well as an optical signal (signal-LED). On

deploying the probe into the borehole, well, reservoir or other,

the optical and acoustical signals will indicate when the probe

touches the water-level, since the electric circuit is closed

by the liquid medium. At the sound of the signal, the depth

can be read off the graduation at the cable in meters and

centimeters.

Furthermore, a multicolor LED indicates the level of the 9 V

monobloc battery.

Optionally we offer a hanging solution to fix the cable drum to

the top of 2 sounding tubes, allowing for an easier handling

in the field.

The FlowFlat mobile measuring system is the result of many

years of experience in the field of magnetic-inductive flow

measurement. Due to the measuring principle (Faradays

law of induction), the FlowFlat does not require any moving

particles in the measuring medium, unlike ultrasonic

Doppler measuring systems. Flow measurements, e.g.

of spring discharges, can therefore be carried out with the

FlowFlat without any problems. The FlowFlat also offers

great advantages over the hydrological vane, especially under

difficult conditions such as turbulent flows, low flow velocities

and/or weedy measuring cross-sections. Changes

in conductivity have no influence on the measurements.

With a measuring accuracy of 0.5 % of the measured value

and a measuring range of 5 m/s, reliable flow measurements

can be carried out from a water depth of just 5 cm in conjunction

with the 20 mm vane rod (accessory). The FlowFlat is

characterized by a robust design, simple operation and a wide

range of applications.

Programming and setting is carried out with the help of simple

menu navigation via the large, backlit LC display and a waterproof

membrane keypad. The measuring system is ready for

use after just a few presettings and the user can start measuring.

All important information (e.g. determined flow velocities

as instantaneous and average values, standard deviation

from the average value) is then displayed. Measured values are

saved at the touch of a button. The memory contents can be

transferred to a Windows PC via the integrated RS232 interface.

The standard scope of delivery includes the magnetic-inductive

sensor with 5 m signal cable (other cable lengths on request),

the operating terminal, an interface cable and an impact-

resistant transport case.

The optional Q4 database and evaluation software (Windows)

is available to users for comprehensive measurement data

evaluation in the office. For more information on the FlowFlat,

accessories and Q4 software, please visit our SEBA homepage

The SEBA LevelSense is a system for aquisition of water level

deviations in ground- and surface waters. Through its easy handling

and the convincing cost-performance ratio it is outstandingly

useful for economic updating of existing measuring sites. When it

is used as a stand-alone instrument, it works totally slip-free with

the approved ball-chain and floater/counterweight system.

As type UnilogLight-ENC*) , the shaft encoder is also available as a

cost effective complete systems with integrated data logger.

The handling is simple: All adjustments inside the Level-

Sense can be done with a notebook or operation terminal (e.g.

HDA). For type LevelSense with display, the desired measuring

value can be set by the level observer by turning of the floater

wheel. The instrument can either be powered externally or internally.

With external power supply, a built-in 9 V monobloc

battery is used as a buffer and provides additional safety in

case of a power breakdown.

The system is available in different versions:

1) shaft encoder (= LevelSense)

2) shaft encoder & display (= LevelSense)

3) shaft encoder & display & logger (= UnilogLight-ENC)

The flow rate is measured in up to 18 layers by an ultrasonic

flow velocity sensor using the pulse Doppler method. An average

flow velocity in the detection area of the sound beam is

then calculated from these values. The total flow at the measurement

cross-section is determined from the average flow

velocity, the water level and the channel profile information.

This measurement method is suitable for free flowing water

and backed up water. The data for water level, average flow

velocity and calculated flow rate are stored locally in a batteryoperated

data logger and transmitted via mobile network to a

central station

The SEBA-Mini Current Meter M1 serves for determination of

the current velocities in laboratories, river models, brooks, small

rivers with low water level and for tubes with small diameters.

Special advantages:

universal application

low starting speed

The Dipper-APT from SEBA provides automatic groundwater

measurements and collection of level and temperature. The

groundwater data logger is only 300 mm long and has a diameter

of 22 mm therefore the Dipper-APT is suitable for applications

in wells from as little as 1.

The installation of a Dipper-APT groundwater data logger is exceptionally

simple and cost effective: In order to monitor and

record the level and temperature variation in a well with its

flash-memory, the logger is simply attached to the casing with

either a thin Kevlar- or steel cable and then lowered down. As

the Dipper-APT is not barometrically compensated, an entire

monitoring system requires just one additional Baro-Dipper.

This Baro-Dipper is utilised to record the barometric pressure.

The variations in barometric pressure are

compensated subsequently fast and simple

with the aid of the DEMASdb software.

For a monitoring network in a geographically

defined area, the installation of a single

Baro-Dipper may suffice. We are happy

to advise and offer solutions to your personal

requirements.

With our operation terminals and software

applications we offer our clients all the essentials

for the set up and operations of an

up-to-date groundwater monitoring system

Output: RS 485 (SHWP, Modbus RTU) for the connection with SEBA data logger

Measuring principle:

The devices emit a continuous radar signal through their

planar shaped antennas. The emitted signal is reflected by the

medium and received as an echo by the antenna.

The frequency difference between the emitted and received

signal is proportional to the distance and depends on the

water level. The determined water level is converted into a respective

output signal and output as measured value.

80 GHz technology:

The 80 GHz technology used enables a unique focusing of the

radar beam and a wide dynamic range of the radar sensors.

The greater the dynamic range of a radar sensor, the wider its

application spectrum and the higher its measurement reliability.

Advantages:

Non-contact radar technology is characterized by extremely

high measurement accuracy. The measurement is influenced

neither by fluctuating product features nor by changing conditions

such as temperature, pressure or dust generation

With the SEBA-Pneumatic Level Type PS-Sensor, SEBA-Hydrometrie

pressure range detection, the PS sensor also meets the highest

demands for measuring accuracy. In addition, the bubbler

has further practical features: a compact, robust design with

integrated compressor and air reservoir ( small space requirement),

an LC display with three function keys, among other

things for measured value display ( easy handling), a large

selection of digital and analogue output signals for connection

to existing (SEBA) data collectors and/or process control

systems ( compatibility) as well as other proven functions,

such as an automatic blow-through device for flushing out

the pressure transmission line. Fast water level changes, e.g.

during lock operation, are also no problem for the PS sensor

.The SEBA-pneumatic gauge type PS-Light-2 serves as a robust,

economic and reliable measuring system for monitoring water

levels in surface waters. The measuring principle is the proportioning

or bubbler system, based upon the other well-known

SEBA instruments in the PS-series. PS-Light-2 pneumatic

gauges have proven reliable in thousands of installations in the

last 20 years around the globe.

An integrated, highly efficient mini compressor, bubbles air

through the pressure tube into the water at adjustable intervals.

The resultant pressure in the tube corresponds exactly to

the hydrostatic pressure above the mouthpiece. This tube pressure

is then measured by a very accurate pressure sensor in the

PS-Light-2. To avoid influences due to obstructions like mud in

the pressure tube, the system is blown out automatically before

each measurement.

The intermittent operation of the PS-Light-2 allows low energy

consumption, and enables operation with batteries or solar panels,

without the need for mains power supply. Together with

a long running lubricant free compressor and a system that

needs no moisture absorbers, the PS-Light-2 can be operated

maintenance-free for very long periods of time.

The basic version of the PS-Light-2 is a sensor with optional output.

However, it can be equipped with LC-display, data logger

or remote data transfer via mobile data. The basic version is delivered

in a robust protective housing (IP 65) suitable for wall or

desk mounting. SEBA PS-Light-2 can be connected to existing

pressure tubes at any time

High precision rain gauge system with impulse output. Suitable

for connection to automatic data loggers (e.g. UnilogLight)

For the best data quality in the most challenging measurement

conditions, the Teledyne Oceanscience High-Speed Riverboat

(HSRB) is the new benchmark for acoustic Doppler current profiling

for discharge measurements. The advanced hull design

allows the boat to slice through standing waves and still maintain

instrument position and data collection. Fast-flowing water,

often problematic with conventional tethered boat designs, can

be handled with relative ease with the High-Speed Riverboat.

The HSRB has gathered data at water velocities over 20 fps (6m/s).

The state-of-the-art trimaran hull design cuts through surface

waves, strongly resists overturning, and maintains instrument

orientation in high flows. For sites where tethered boat measurements

have been impossible, or data were too poor to be of

value, the High-Speed Riverboat is the solution. The High-Speed

Riverboat is strong and robust to cope with the worst deployment

conditions

Teledyne Oceanscience Q-Boats are the number one choice

for reliable remotely-controlled acoustic Doppler current profiling

in streams, rivers, lakes and coastal waters all over the world.

Whether you need to reduce your survey time, keep people safe

during difficult conditions, or access hard to reach locations, there

is a Q-Boat to suit your survey and your budget.

Portable and Convenient

The use of lightweight and resilient ABS hulls and a collapsible

sliding crossbar makes the boat convenient for a single operator.

Transportation to and from the deployment site is easy; simply

slide the outriggers towards the main hull and pick up with

one hand. To deploy the boat, slide the outriggers back, place

the boat in the water, and start your measurement process.

Robust and Powerful

The IP67 rated Q-Boat 1250 has an innovative propulsion system

that uses two thrusters, one in each outrigger. An advanced

2.4 GHz remote control transmitter differentially adjusts the

two thrusters to steer the boat. The result is a robust and highly

maneuverable boat with no rudder or steering linkages.

The Q-Boat 1250 can attain a 2.3 m/s (7.5 fps) top speed

using the standard battery pack, and the remote control

transmitter can be adjusted to allow effective profiling at speeds

as low as 30 cm/s (1.0 fps).

Cost Efficient

Select survey sites based on best measurement locations. The

Q-Boat 1250 does not need a tether line or bridge for deployment,

which saves time and resources. Simply deploy your

Q-Boat and start collecting your ADCP data

The Teledyne Oceanscience Riverboat SP is the top choice for

deployment of the TRDI StreamPro acoustic Doppler current

profiler. Upgrade from the standard StreamPro float to the more

stable, rugged, and corrosion-resistant tethered boat. The Riverboat

SP makes safe, easy measurements of discharge in relatively

slow and fast-moving waters.

The Riverboat SP can gather data at water velocities over 12 fps

(3.6 m/s). The proven bow flare trimaran hull design prevents the

boat from nose-diving and maintains instrument orientation by

reducing pitch, roll, and yaw in varied flows. The trimaran design

reduces drag compared to catamaran designs making the Riverboat

SP capable of operation in a range of water velocities. Long

fins improve stability in very low-flow environments.

Made of unbreakable polyethylene, the Riverboat SP is strong

and can handle tough deployment conditions. The standard boat

configuration fits a 2 TRDI StreamPro ADCP, and the latest instrument

clamp is suitable for the StreamPro with or without an internal

compass upgrade. Large kick-up fins are standard to ensure

snag-free operation.

Features: For use in water velocites up to 12 fps

All required items included for easy plug-and-play

operation

Single or dual person mobilization

Made of molded unbreakable polyethylene

Easy transportation inside the available soft or hard case

Optional Cable Chimp II remotely-operated vehicle

available for slow consistent measurements

Top Pieces are a reliable cover for observation wells and their

permanent protection. The very robust design, made of a

special alloy, makes them resistant to corrosion and weather

(frost-proof).

Due to a dual locking of the lid with the base maximum

security is achieved. Construction allows for a quick opening

and closing of the top piece with a small key - even in

winter.

You can chose between standard and

safety lock (with secured 5-pointhead)

Available sizes: 1, 5 to 6 diameter.

The flood-tight Top Piece is a specially

constructed top piece with a watertight

inlet made of PVC and a handy

strap for easy take out

low starting speed of 0, 025 m/s

almost frictionless contact transmission

unit composed system

Description:

The SEBA-Universal Current Meter F1 serves for use on rods

(pic. 1, 2, 3) as well as for cable-suspended-current meter

equipments (pic. 4, 5) for use with SEBA single drum winches

or cable way installations.

Meterbody:

The streamlined meterbody and the axle are manufactured of

high-quality, non-corrosive steel. The hub of the propeller is

filled with oil and rotating in two special ball-bearings. The oil

filling and a capillary seal protects against water entry. A base

stop prevents the propeller from striking the ground.

Contact transmission

One signal is generated from each revolution of the propeller

by means of a permanent magnet. Frictionless operation increases

the sensitivity of the instrument. The contact mechanism

is quickly interchangeable without problems.

Instrument case:

Robust version made of stable plastic material with two cover

hinges.

With this full-electronic counter it is possible to receive frequencies

for all flow velocities. The impulses generated by the

current meter are added and indicated in relation to the preselected

time. The timing starts from the first impulse.

With the basic version, the impulses can be counted in freely

pre-definable measurement intervals. Optionally, the impulse

number to be counted can be pre-selected (Z6-I). A further option

is the direct calculation of the current velocity by means

of pre-definable equations (Z6-V). There are several memory

locations for all adjustments. All the user-defined adjustments

can be made directly at the device or via connected PC and

can be saved permanently

MiniOFS is designed by Dr. Sten Lofving is used to mke direct measurements of visual range.The sensor is sensitive for particels in a zone about 25cm ahead of the location of the sensor who limit the visibility in the air. These particles are normally the microscopic water particles costituting fog , but they may also be snowflakes' raindrops or air pollutants. But mmost indications of low visibility are because of fog or snow

The PWSMini is designed by Dr.Sten Lofving is a spin off from our MiniOFS sensor and it is probably the cheapest present wheather sensor on the market. And it is very compact -width is only 68mm. this little sensor measures 3 important wheter parameters.
