Open Channel Flow Meter

SIRIS MCERTS-certified ultrasonic open channel flow measurement devices offer an accurate and reliable solution for measuring flow rate through open channels and are the preferred method of measuring flow rate (gauged head) through an open channel hydraulic structure, such as a flume or v-notch weir.

Ultrasonic flow meters measure flow rate by continuously transmitting pulses of high frequency sounds and waiting for an ‘echo’ to determine the exact height of the water as it passes over a flume or weir.
