The DOF6000/AVFM 5.0 flowmeter consists of a submersible probe with integrated ultrasonic transducer to measure velocity and level at the same time, and a flow processor-calculator with digital display.

It works by calculating the velocity and height of the cross-sectional area of the partially filled pipe, or an open channel or river.

The processor displays speed, level, flow and flow totalizer. It has a 4-20mA output associated with the flow. As an option, it can include a Datalogger with data storage that allows recording the instantaneous and total flow, maximum, minimum, average, etc. saving them in internal memory with USB download.
