NYCSUL two-wire ultrasonic level meter is an intelligent non-contact liquid level measuring instrument. The product has automatic power adjustment, gain control, temperature compensation, the use of advanced detection and calculation technology, interference signal suppression function, thus fundamentally improve the measuring accuracy of the instrument, to ensure the authenticity of the measurement results. Products can be widely used fbr liquid level measurement of various liquids, but also for distance measurement.

Ultrasonic Level Transmitter Operating Principle

The ultrasonic level meter is installed at the top of the container. Under the control of the electronic unit, the probe transmits a beam of ultrasonic pulse to the object under the control of the electronic unit. The acoustic wave is reflected by the surface of the object. Some of the reflected echoes are received by the probe and converted into electrical signals. According to the time difference between retransmission and re-receiving of ultrasonic wave and the known speed of sound, the change of object level is determined. The microwave signal is processed by electronic device, and finally transformed into electrical signal related to object level.
