Open Channel Flow meters

OCF 6.1 – Non-Contacting Open Channel Flow Meter

Greyline’s OCF 6.1 continuously measures, displays, transmits and controls liquid level in storage tanks and pumping stations.

It also measures the open channel flow through any flume or weir. Calibration is simple with the built-in 5 button key pad and the isolated 4-20mA output transmits level or flow.

There are 2 built-in programmable control relays. The optional built-in data logger stores 26 million points data logger and flow reporting system and the data is easily downloaded to a memory stick via the built in USB port.

Flow meter Ultrasonic

The OCF 6.1 is an open channel flow meter that doubles as a tank level meter, making it a perfect solution for both non-contacting flow measurement and level measurement. The ultrasonic sensor supplied with the OCF 6.1 mounts just 203.2 mm above the flowing water giving +/- 0.25% accuracy. 

Use the OCF 6.1 in open channel flow mode for non-invasive flow, irrigation flow monitoring, industrial flow monitoring, and influent and effluent flow.
