The ultrasonic water level meter is arranged above the measured water level, the sensor in the ultrasonic water level meter transmits ultrasonic pulse to the water surface after being electrified, the ultrasonic pulse passes through air to reach the water surface and then is reflected back, and the partially reflected echo is received by the same sensor and is converted into an electric signal. The time taken from the transmission of the pulse to the reception, i.e. the transmission time of the pulse, is proportional to the distance of the sensor from the surface of the medium. The distance from the sensor to the water surface can be calculated according to the transmission time of the pulse and the speed (340 m/s) of the pulse, so that the height of the water level can be calculated.

In the prior art, the sensor is generally directly connected through a flange or threads to enable the ultrasonic water level gauge to be perpendicular to the water surface, but the ultrasonic water level gauge is easy to incline due to vibration or shaking in the use process, or is not easy to keep perpendicular to the water surface due to movement of a worker, so that an error is generated in a measuring result, and judgment of the worker is affected.
