WL-1A1 Ultrasonic Open Channel Flow Meter

WL-1A1 Ultrasonic Open Channel Flow MeterStandard weirs are used as auxiliary measurement methods, mainly including: full width weirs, rectangular weirs, triangular weirs, Paschal troughs, and P-B troughs. Currently, the Paschal trough is more commonly used. The entire open channel flowmeter consists of three parts: a converter, a weir tank, and an ultrasonic level gauge.

WL-1A1 Ultrasonic Open Channel Flow MeterIn a smoothly flowing open channel, a measuring weir channel converts the flow rate into the level of liquid. By measuring the water level, the flow rate can be calculated backwards. Install a measuring weir groove in the channel to generate throttling effect, so that the flow rate in the open channel has a fixed correspondence with the liquid level. This correspondence mainly depends on the structural dimensions of the measuring weir, minimizing the impact of the channel. Non contact measurement: The sensor is not in contact with the fluid and is not corroded or contaminated by sewage. Strong corrosion resistance, good waterproofing, and moisture resistance.
