Measurement by level-speed
Sensors that are immersed in the bottom of a river, canal, duct or pipe and measure water velocity and the fluid level.
From the speed, the level and shape of the channel, it can be determined the flow rate the volume of water flowing in a given period of time.
Water speed
Water speed can be measured through sondas de molinete immersed in the river or canal fluid.
This parameter will not display the flow directly, except if the section of water is known. The direct output information is the power and speed.
