Description
An ultrasonic level transmitter is a non-contact device that measures the level of liquids or solids using high-frequency sound waves. It works by emitting an ultrasonic pulse from a piezoelectric transducer and measuring the “time of flight” for the reflected echo to return. This time is then converted into a distance or level measurement, which can be sent as a standard signal to control systems. Ultrasonic level transmitters are useful in industrial settings, especially for corrosive or hot liquids, but they can be affected by factors like heavy vapors, turbulence, or dust
