open channel flowmeter in municipal STP flow monitor, ultrasonic flow meters,
Ultrasonic transducer, is a transceiver which emits high frequency sound, which hits the medium surface and returns back to the sensor receiver. The time of travel of the ultrasound is inversely proportional to the height of the flowing medium. This way the height of the flowing medium is calculated. And with the algorithms programmed the Height, Flowrate and Total Flow are calculated and displayed.
When use the transit time ultrasonic flowmeters, be sure that the fluid can adequately conduct ultrasonic waves, because the flowmeter will not measure when the ultrasonic waves cannot penetrate the flow stream between the transducers. Similarly, ultrasonic waves must be able to penetrate the fluid for Doppler flowmeters to operate accurately. When the fluid is relatively opaque and does not penetrate the fluid, Doppler flowmeters tend to measure the velocity of the fluid at or near the pipe wall, which can cause significant measurement error and/or cause the flowmeter to fail.
