JL-LDB Bacher trough flowmeter

JL-LDB Bacher trough flowmeter

The composition method of JL-LDB ultrasonic open channel flowmeter measurement system generally consists of one flow display instrument, one flow meter, and one liquid level meter; A multi-point flow velocity measurement open channel flow system can also be composed of one flow display instrument, four flow meters, and one liquid level meter. The HOH-L-01 intelligent open channel flowmeter system is suitable for measuring the flow of rectangular and trapezoidal open channels and culverts in reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, farmland irrigation, water management and water resources. There are many types of open channel flow meters, including weir type open channel flow meters and trough type open channel flow meters. Ultrasonic open channel flow meters come in various shapes, including U-shape, trapezoid, rectangle, etc., in addition to circular ones.

Bacher trough is an auxiliary equipment for measuring open channel flow, and is also known as a water tank in hydraulic experiments. The advantages of the Babbitt trough are: it is almost unaffected by changes in conditions such as pipe wall roughness, and the long-term variation of measured values is small; The head loss of the Bacher trough is relatively small in non full pipe flow instruments, and even if there are solid substances in the water, they hardly settle, with little impact on the flow velocity and the water level on the downstream side.
