Ultrasonic Level Transmitter Ultrasonic Level Transmitter is specifically designed for continuous non-contact liquid level measurement. The transducer (probe) sends out high frequency ultrasonic pulses. When a pulse hits the surface of measured liquid, it is partially reflected. The reflected wave is received by the transducer and converted into an electronic signal. The distance from the transducer to liquid surface is calculated according to the time difference between pulse transmission and reception and velocity of sound wave. Because Ultrasonic Level Transmitter sensor is contactless,...
