Work Principle

The BUL-200 split-type ultrasonic level gauge series controls the circuit of ultrasonic drive to send pulse excitation signal,drives the ultrasonic sensor to send ultrasonic wave,and the ultrasonic wave is received by the ultrasonic transducer after being reflected by the liquid level to be measured.Based on the time the sensor transmits and receives the ultrasonic waves,the height of the liquid level can be calculated.

H-the distance from the ultrasonic sensor probe to the bottom of the liquid to be measured,S-the distance from the ultrasonic sensor to the liquid level,h -the height of the liquid level to be measured,v-the propagation speed ultrasonic waves in the air,andt-the time from transmission to reception of ultrasonic waves.Based on the above parameters. the following equation can be derived：
