A flowmeter is a device used to measure the speed of water. This tool achieves water velocity by relating it to the number of revolutions measured at a given time interval.
For meteorology and hydrometry, vane series rollers are more useful. Blade rollers are suitable for measuring high speeds. There is a linear relationship between water velocity (v) and the number of revolutions of the roller shaft (n), which is as follows:
V = a + bn
b: The hydraulic step of the flowmeter impeller (meter per round) obtained by the chariot test on the channel.
n: Impeller rotation (rpm)
a: Flowmeter constant (meters per second) obtained by the chariot movement test on the channel.
