Water current meter Pigmy cup type used for determining velocities of flowing water in open channels and streams has been manufactured to meet the requirements of I.S.3910.
The cup type water current meter consists of a six-cup assembly having six cup mounted on a vertical shaft. This shaft is held vertical in a yoke frame on two pivot points .
This yoke frame while holding the moving assembly protects its cups from damage from the Floating bodies in flowing water also. The vertical shaft rest on a pivot point at the lower end, which is adjustable.

The Current Meter Consists of the Following Accessories :
- Water Current Meter Sensor
- Suspension wading Rod 120 C.M. long.
- Connection wire with clip 5M. Long.
