Sr. No.	Activity / Parameters	Range	Accuracy
1	Calibration of rotating type current meters viz. Cup, Propeller, Pigmy Cup and Pigmy Propeller	0.01 m/s to 7.5 m/s	0.1% in the speed range of 0.01 m/s to 0.099 m/s 0.05% for the speed range of 0.1 m/s to 7.5 m/s
2	Performance testing of Electromagnetic, Acoustic Doppler Current Profiler (ADCP), Paddle Wheel, Self-recording, Direct Velocity Indicator type and Non-contact type current meters	0.01 m/s to 7.5 m/s	0.1% in the speed range of 0.01 m/s to 0.099 m/s 0.05% for the speed range of 0.1 m/s to 7.5 m/s
3	Performance testing of Non-contact type Water Level Sensor	0 to 30 m	2 mm
4	Drag force evaluation for various sizes and shapes of water vehicles under different conditions such as depth of submergence, angle, add-on weights and different directions of flow at various trolley speeds	—	—

Unique Features of the Current Meter Calibration Laboratory

The rating tank is 228 m long and 3.66 m wide, consisting of a shallow water section of 0.84 m depth for 53.30 m and a deep water section of 2.13 m depth for 175.30 m.
Upgraded under National Hydrology Project (NHP) in September 2020.
Automated electrically driven rating trolley operates both onboard and remotely with real-time PC-based data acquisition, processing and error diagnostic system.
Calibration parameters conform to BIS 13371 / ISO 3455.
The laboratory is equipped with a regular wave generation system and spin-time measurement system.

In addition to supporting government agencies, academic institutes, suppliers and manufacturers of various types of water current meters also use this facility for testing and calibration of the above-mentioned parameters.
