This flow current velocity meter is smart, aesthetic appearance, compact design, simple operation, convenient when measuring. It is widely used to measure the flow current velocity in river, irrigation canal, surface run off, hydrological experiment, and measuring pipeline flow to test the efficiency of the pump station, waste water monitoring and see page flow measuring in the Environmental protection.
* Protect Grade: IP65
Operational Principles and Calculation
In the measurement, the Propeller current meter was rotated by the water power, the signal device generates the revolution signal, and the flow velocity can be calculated by the following formula:
V＝ KN ÷ T ＋ C(m/s)
In it ：V：The mean flow velocity during the measurement(m/s)
K：Screw pitch C：Constant of the current meter
T：the amount of time of the measurement(unit: s)
N：The number of signals during T
During the use of the device, K and C both are constants. The flow velocity can be calculated once the value of T and N are obtained.
