The ultrasonic transducer sensor is an ultrasonic pulse signal sent by an ultrasonic probe, which is propagating in the gas, and is reflected after meeting the interface of air and liquid. After receiving the echo signal, the ultrasonic round-trip propagation time is calculated, and the distance or liquid level can be converted by height. However, if there is stirring in the on-site container and the liquid fluctuation is relatively large, it will affect the measurement of the ultrasonic liquid level gauge, and there will be no signal or severe data fluctuation.
The reason for the measurement failure of the ultrasonic transducer circuit is that the measurement of a few meters of the ultrasonic liquid level gauge ,which refers to the calm water surface. In the case of stirring in the container, the water surface is not calm, and the reflected signal will weaken to the normal signal. so the measuring value of the ultrasound will be disturbed.
