The IS-6000 Dopplerstationary ultrasonic flow meter continuously measures the flow of water and wastewater in pressurized and partially filled pipes and in open channels with water depths from 1.5…80 in. (0.04…2 m).

As a standard, the flow meter consists of a transmitter and an ultrasonic area velocity sensor for combined velocity and water level measurement. Discharge is then calculated by multiplication of the average flow velocity and the wetted cross-sectional area.
