Gravimetric Calibration laboratory:

Gravimetric calibration facilities available conform to ISO 4185 for calibration of flow meters, testing of filters and ascertaining valve characteristics. The principle employed in the gravimetric calibration facility is to accurately weigh the quantum of water passing through the flow meter under calibration at constant flow rate in a precisely known interval of time.  The ratio of weight to time is the primary measure of flow rate against which the flow element is calibrated.

Volumetric Calibration laboratory:

Volumetric calibration facilities available conform to ISO 8316 for performance testing of submersible pumps, calibration of flow meters, testing of filters, ascertaining valve characteristics. The principle employed in the volumetric calibration facility is collection of water in a known volume of tank and the time taken to fill the same.  The ratio of volume to time is the primary measure of flow rate against which the flow element is calibrated. 

Hydraulic Machinery - Numerical Simulation Laboratory (HM-NSL):

Echo sounder Read out unit with recorder

The echo sounder sensor is fixed in the boat with its sensor immersed in the water and is connected to read out unit which will show the water depth as the boat is moved in the reservoir area. These depth values displayed on the read out unit can also be recorded on the chart provided with the echosounder read out unit. This depth data along with GPS position data given by DGPS unit is recorded in the Laptop and through navigation software we can compute the present reservoir volume.

Telemetry Testing

Very large no of Automatic Weather Stations (AWS), Surface Water Stations, Ground Water Stations, etc are already being installed or in the process of installation by State and/or Central Implementing Agencies under National Hydrology Project(NHP). Telemetry Installations for GSM/GPRS communication mostly include Cable & Antenna. For maximum data reception availability, parameters such as cable faults, Voltage Standing Wave Ratio (VSWR), Impedance etc., are required to be checked for proper & efficient transmission and reception of data. For laboratory and Field testing of above mentioned Telemetry parameters, CWPRS developed Telemetry Testing Facility is useful for testing Telemetry installations installed under NHP as well as for all across India.
