Flow monitoring

Explore by meter type

Our flow meter types

We have designed a suite of instruments to measure flow in open channels, closed pipe and area velocity options.

OPEN CHANNEL

Our open channel ultrasonic flow meters integrate our digison ultrasonic sensors with our USI and USM meters

CLOSED PIPE

Using a Magflow sensor, our closed pipe flow meters can be used with an integral screen or USI meter

AREA VELOCITY

Integrating our USI and USM meters with our area velocity Doppler sensor for effective area velocity flow meters

Why measure flow in water and wastewater?

Usually, the main driver for flow monitoring in wastewater is for billing purposes. A trade effluent bill uses the flow and other water quality parameters to calculate what you owe. The water company is required by law to use your readings, as long as they are from an approved measurement type.

Other reasons to measure flow may be during the manufacturing process in industrial applications, for wastewater treatment plant automation or for flow volume based sampling in a wastewater sampler.

Measuring flow in closed pipes with the Sonic Driver Pocket-UFM

The Pocket-UFM from Sonic Driver is an innovative handheld clamp-on ultrasonic flowmeter that truly fits in the pocket. Because clamp-on meters require no cutting of the pipe to install them and have no effect on the flow in the pipe they are a preferred method for the measurement of liquid flow in closed pipes. The meter incorporates heat quantity measurement and wall thickness measurement functionality as standard.
