Detailed Product Description

It is a supersonic liquid level sensor combining the sensing technique with electric signal processing and is internally equipped with a supersonic sensor and temperature sensing elements. The sensor probe emits a series of supersonic pulses, and when encountering liquid level, the supersonic pulses return and are accepted by the sensor. The filtering device in the sensor can identify the true echo waves returned from the liquid level among various false echo waves from sound waves, electric wave noises and rotated agitator palm noises.  After temperature compensation, the time for the impulse waves to be emitted to the liquid level and then to return the sensor can be converted into displayable distance and into current for output.
