Ultrasonic level instruments works on the basic time-of-flight principle which states that sending a sound wave from a peizo electric transducer to the contents of the vessel, which may contain liquid, solid or slurries level.This liquid level sensor comprises two elements such as an associated electronic transceiver and a transducer with relatively high efficiency. In case of a liquid level controller, the fluid level can be determined by measuring the trip time difference between a transmitted ultrasonic pulse and a reflected echo.The frequency range for ultrasonic methods varies from a rang...
