Ultrasonic Level Transmitter

The Time-of-Flight theory underlies the operation of the ultrasonic level meter. Ultrasonic pulses are sent by a sensor, which then detects them again after being reflected by the media’s surface. The distance traveled is directly inversely proportional to the Time-of-Flight of the reflected ultrasonic signal. It is possible to determine the level using the known tank shape.

For continuous level monitoring of liquids or bulk materials, use an ultrasonic level meter. The measuring of liquids in open basins or storage tanks is typical uses. The sensor can also be used to find bulk materials in open containers or tiny vessels. The non-contact measuring approach enables a setup without a medium and is unaffected by product attributes.
