Ultrasonic open channel flowmeter can be equipped with Bacher groove

>The ZMH-D ultrasonic open channel flowmeter has the advantages of simple structure, easy installation, good measurement accuracy and reliability, and wide range ratio. It can be used for measuring sewage and wastewater discharge, as well as for water metering in agricultural irrigation and drainage renovation projects in urban areas. The ultrasonic open channel flowmeter consists of a flow integrator, an appropriate measuring weir, and an ultrasonic probe.


Range: 10 liters/second to 10 cubic meters/second (range depends on the equipped weir)

·Accumulated traffic range: (counting back to zero for full 8 digits)

·Flow error is related to the amount of water used in the weir tank

Equipped with triangular weir: 1-2% Equipped with rectangular weir: 1-4% Equipped with Bacher trough: 3%

Equipped with no throat groove: 4% Equipped with P-B groove: 4%
