Ultrasonic open channel flowmeter for measuring the outflow of river water diversion

Ultrasonic open channel flow meters are used in conjunction with corresponding Bacher troughs, triangular weirs, rectangular weirs, and other weirs to measure the liquid level height using the propagation law of ultrasonic waves in the air. The liquid level information is continuously transmitted to the host, which automatically measures the instantaneous flow rate and cumulative flow rate through the computing system and stores them.

This instrument can complete flow detection without contact with fluids, and has complete liquid level measurement, control, data transmission, and human-machine communication functions. This machine is a flow measurement instrument that integrates ultrasonic transmission and reception sensors, servo circuits, temperature compensation sensors and compensation circuit units, integration host, display, control signal output, and serial data or analog output units. The measurement of fluid flow in many non full water, high flow (or low flow), naturally flowing free surface states is called open channel flow detection. Due to the large or small flow rate in open channels, there is often some corrosiveness or impurities carried in the fluid, making it difficult to detect the flow rate using a general pipeline flowmeter. For example, in the fields of industrial enterprise drainage, hospital wastewater, agricultural irrigation water, urban groundwater drainage, etc., open channel flow detection, especially non-contact ultrasonic open channel flow meters, are flow monitoring instruments.
