Ultrasonic flow meter iSonic 4000
for flow and level measurement in open channels, semi-filled pipes and tanks/reservoirs
The iSonic 4000 is an intelligent and versatile ultrasonic meter / controller designed to measure level, volume and open channel flow.
It is used for influent and effluent measurements, flow control and data logging.

Ultrasonic flow meters
Ultrasonic signals are alternately sent in and against the flow direction. Ultrasonic energy bursts are transmitted and received via well-defined paths across the flow stream. The velocity of the flow is accurately measured by the difference in the arrival times of signals from the upstream and downstream transducers. The transit time difference ( Δt = t 2/1 – t 1/2) determines the average flow velocity.
