Series AFG Averaging Flow Grid

cost effective air flow station for ducts up to 60"

the series afg flow grid is an outstanding simple yet accurate cost effective alternative to other duct mounted pressure sensors. Once installed and connected to a suitable measuring instrument, the device will provide years of trouble free monitoring of both air and gas flow. Installing the afg flow grid is quick and easy, the afg is supplied in kit form to allow both workshop and on-site installation into a wide range of square and circular ducts up to approximately 60".

the afg flow grid is a fundamental pressure sensing device designed to transmit a continuous differential pressure signal. When this output is connected to a suitable measuring instrument (i.e., manometer, pressure transducer, etc.), it may be used to determine air velocity and volume flow rate.

how the afg flow grid works

the afg flow grid consists of two tubes mounted diagonally across a square or rectangular duct, or diametrically across a round duct. The tubes are drilled with a series of equi-spaced holes.

the holes in one tube face directly upstream and sense total pressure, while the pairs of holes in the second tube also face forward but at an included angle of 79 degrees, sensing static pressure. The total and (sub) static pressures are averaged along the length of each tube and provide pressure signals at connectors outside the duct wall. The pressure differentials across these connectors constitute the output signal.

product applications

to display differential pressure, velocity or volume flow using a micro manometer, gage, or transmitter

to give a warning of over or under flow rate using a pressure switch

to control air supply in a system by connecting the grid to a pressure transmitter with an electrical output which can be used to feed into a control system

to display differential pressure on a simple fluid manometer to give visual indication of changes in volume flow rate in the duct

Magnetic Inductive Flow Sensor (Series MFS)

series mfs magnetic inductive flow sensor

no moving parts, frequency and 4 to 20 ma output, maintenance-free

the series mfs magnetic inductive flow sensor is a compact, low cost alternative to paddle wheel sensors. Unlike sensors with moving parts, the mfs can be applied in applications dealing with contaminated media. This series provides a reliable measuring technique, an obstruction free pipe cross-section, as well as a quick response time, making this series ideal for interference free operation. Any change in temperature, density, viscosity, concentration or electrical conductivity of the liquid, does not affect the output signal of this magnetic inductive flow sensor. This, in addition to its long-life cycle, makes this series perfect for accurate reversible gauging of volume flow of conductive liquids in closed piping.

principles of operation

the measuring pipe is in a magnetic field. If an electrically conductive medium with a certain flow passes through the pipe, it passes at a right-angle to the magnetic field, creating a voltage which is proportional to the average flow velocity and picked up by two electrodes within the mfs. A frequency output signal is obtained that is proportional to the flow (analog output option available).

Particulate Sensor (Series PMS)

series pms particulate sensor

reliable operation, minimal maintenance

the pms particulate sensor employs a field-proven combination of passive-induction and protected-probe technologies. As particles flow near and around the probe, minute currents are dynamically induced into the probe by flowing particulate. A dsp processes the signal into an absolute output that is reasonably linear to mass. Protective layers over the probe work in combination with induction-sensing to ensure reliable operation with all types of particulate including moist powders and highly conductive dusts. Maintenance is minimal and there is no need for an air purge. For durability, the sensors are passive and free of electronics. The pms particulate sensor is designed to be used with the dpm particle monitor in order to be intrinsically safe.

Duct And Immersion Building Automation Temperature Sensor

Series TE Duct and Immersion Building Automation Temperature Sensor

Available up to 18" Probe Length, Thermistor or RTD Outputs

The Series TE Duct and Immersion Temperature Sensor can be used to monitor air or water temperature throughout a building management system or an air handler unit. Flanged duct sensors monitor the supply or return air and provide a thermistor or RTD output to the digital controller. Immersion sensors which are supplied with compression fittings are typically used to monitor the hot or chilled water lines throughout a building. Thermowells are recommended, but not required on the immersion sensors.

For variable air volume applications, the Series TE can be configured to have 8' plenum rated cable with flying leads. Standard units come with 4" leads with an integral terminal block to eliminate carrying extra wire nuts. For housing models, multiple knockouts provide easy conduit access to any side of the housing. The 1/4 turn lid comes with a chain to prevent it from being lost during installation.
