TULI Integrated Ultrasonic Level Transmitter

Operating Principle

Classic ultrasonic echo analysis method: The ultrasonic transducer emits ultrasonic pulses, which are reflected back upon hitting the surface of the measured medium. The same transducer receives the reflected echoes and converts them into electrical signals. By measuring and analyzing the time difference of the echoes returning from the liquid surface, the distance from the sensor to the liquid surface can be calculated.

Product Application

Used for liquid level or differential level measurement at various process points in wastewater treatment plants, water treatment plants, pump stations, collection wells, biochemical reaction tanks, sedimentation tanks, and sludge storage tanks.
