Overview
About the Open Channel Flow Meter WF9000.V5.
The WF9000.V5 open channel flow meter measures flow in open channels such as effluent and sewage discharge lines. An ultrasonic 3-wire sensor measures the head height above a primary device, and the programmable controller converts it into flow rate for V-notch plates, Parshall flumes, weirs, venturi channels and similar structures. Continuous measurement with ±1% of full scale accuracy and built-in logging give dependable flow data, helping operators run treatment plants efficiently, optimise processes before investing in extra capacity, and specify upgrades with confidence. The package includes the controller, ultrasonic sensor, panel and sensor bracket, and a solar powered version is available for remote installations.
