Ultrasonic liquid level meter is a monitoring instrument to measure the height of liquid, tank height and material position. The meter itself can adopt 2-wire, 3-wire or 4-wire technology.
The remote type ultrasonic level/liquid meter measures the time required for an ultrasonic pulse to return throughout the process from the time it is sent out to the time it returns. The ultrasonic level meter is installed vertically on the surface of the liquid, it sends an ultrasonic pulse to the liquid surface, after a period of time, the sensor of the ultrasonic level meter receives the signal reflected back from the liquid surface, the signal is selected and processed by the transmitter circuit, and the distance from the liquid surface to the sensor is calculated according to the time difference between the ultrasonic level meter sending and receiving ultrasonic waves.
The remote type ultrasonic liquid meter is widely used for liquid level and volume measurement of tanks, pools and reservoirs, and also for flow measurement of open channels.
