This is a compact, easy-to-use system for measuring the velocity and depth of water in rivers and streams, open drainage channels, and large pipes.

It is suitable for use in a wide range of water qualities ranging from sewage and wastewater to clean streams, potable water and even sea water. This model incorporates a backup lithium battery for the RAM which allows for
logged data to be stored for some months / years until power is restored.

The instrument measures forward and reverse flow conditions and may be programmed to computer flow rate and total flow in pipes and open channels.  The ultrasonic transducer assembly is profiled to reduce flow disturbance.

It is designed to be placed at (or near) the bottom of the water channel for upstream measurement. A single cable connects the instrument to a 12V DC power source.
