Ultrasonic level transmitter is a non contact type level measurement transmitter for continuous Monitoring of liquids. It has an integral electronic Module for measuring level along with transceiver. ultrasonic is compact and easy to install measuring Device. ultrasonic is suitable for all non foaming and Non fuming liquid.


Ultrasonic works on the principle of Ultrasonic Sound waves. Sensors generate high frequency Sound waves and evaluate the echo which is Received back by the sensor. The device calculates The time interval between sending the signal and Receiving the echo to determine the distance to an Object, by the following formula: Distance = (Velocity of Sound x Time)/2. Velocity of sound changes with temperature andNature of medium.
