The measurement is based on the speed of a sonar signal in fluid. The signal emitted by the transducer travels through the liquid and is reflected from the interface, solids or surface level. The travel time is measured and converted to digital and/or analog outputs. Multiple interfaces can be detected and measured reliably.

Sonar is mostly associated with SUBMARINES, nevertheless at present many devices in different fields utilize general sonar principles and have been accepted as accurate and reliable.

From the beginning Transducer USA has been focused on SONAR transducer technology and its use in liquid level measurements. Our mission is to produce the most accurate and reliable transducer possible. Since 2001 we have tackled some of the most difficult measurement applications. Today we provide the best and most reliable transducer technology to our clients.
