ABSTRACT:
A method and device for measuring flow rate of a liquid through a gate in a channel. The device having a first pressure sensor for measuring the pressure of the liquid at a first position upstream of the gate. A second pressure sensor for measuring the pressure of the liquid at a second position downstream of the gate. An opening sensor for measuring the position of opening of the gate and a processor for calculating the flow rate using an algorithm based on the measurements.
