This is a 4-component net-radiation sensor that is used for scientific-grade energy balance studies. The instrument has separate measurements of solar (Short Wave or SW) and Far Infra-Red (Long Wave or LW) radiation. Major improvements relative to comparable instruments include weight (reduced), solar offsets in the LW signal (reduced), ease of leveling (high, because leveling assembly is included).

The propeller type current meter is a world recognized instrument. This current meter is suspended in the water using a cable with sinking weight or wading rod and will accurately measure stream flow velocities from 0.01 to 3.5 meters per second with Multiple propellers. Magnetic current meter has a permanent magnet mounted on its shaft. In every revolution of the cup wheel the magnet actuates the proximity resulting in one make and break of the contacts. The free ends of the proximity switch cable are connected to an automatic counter, which registers one count for every revolution of the wheel. The calibration chart provided with the meter gives the velocity in m/sec. Output: switch closure

Extremely short microwave impulse are emitted by the antenna system to the measured product, reflected by the product surface and received again by the antenna system. the time from emission to reception of the signals is proportional to the level in the vessel. A special time spreading procedure enables the reliable and precise measurement of the extremely short signal running times. The radar sensors are available in different C and K-band frequency ranges, this ensures the optimum solution for the different applications. The proven ECHOFOX signal processing analysis the refelections in the vessel based on long-standing experience and detects the level signal reliably.

The load cell used for the measurements was a Cantilever beam type 200 Kg capacity with 3.0 mv/V rated output and a non-linearity of 0.03 FSO. The load cell is corrosion resistant (stainless steel) and hermetically sealed for use in outdoor environment. The snowfall is received on a MS platform of 50cmx50cm size. This area corresponded to 120 cm of SWE. The load cell was fixed between a bottom MS plate and a top MS plate, both of 4 mm thickness, through a separate fixing arrangement so that the load is uniformly transmitted to the centre of the load cell. Dimensions of the top plate were 490mm x 490mm whereas that of the bottom plate were 479mm x 479mm, thereby providing a 5 mm gap to facilitate a free vertical movement of the top plate during loading

Radar Type Water Level Sensor is used to measure the level of liquid in storage tanks and open basins. We are one of the pioneering Manufacturers, Exporters, and Suppliers of Radar Type Water Level Sensor from Uttarakhand. The Radar Type Water Level Sensor that we offer consists of 16x2 LCD alphanumeric display and 4 2 membrane keypad. Our Radar Type Water Level Sensor comes with a data logger that is used to collect the real time data. It is based on non-contact measuring principle.

Applications :

• Level in liquids : Two different emitting frequencies are available for these applications. The compact, high frequency K-band sensors VEGAPULS 61, 62 and 63 are particularly suitable for applications for which high accuracy is required. Through the small antenna sizes, an excellent signal focusing is reached and hence mounting on small mounting openingsn is possible. The low frequency C-band sensors VEGAPULS 65 and 66 can penetrate foam and strong condensation and are thus particularly suitable for arduous process conditions. Unaffected by steam, gas composition, pressure and temperature changes the radar sensors detect the product surface of different products reliably and ensure thus an optimum process.
• Level in bulk solids : The high frequency sensors VEGAPULS 67 and 68 in K-band technology are used for these applications. Thanks to the very good focusing of the signals, the level is detected reliably independent of silo installations or buildup on the vessel wall. A high sensitivity electronics optimized to the requirements of the bulk solids measurement, enables a reliable level measurement of different products up to a distance of 75 m. The measuring principle is unaffected by strong dust generation, filling noise, air turbulence by pneumatic filling and temperature fluctuations and ensures a reliable and maintenance-free operation of the systems. The application area covers applications in the food processing industry and the plastic processing up to the steel generati- on and mineral rock processing.
