A Dynamic Water Level Detector Based on Acoustic Attenuation Change

Abstract

The invention discloses a dynamic water level detector based on sound wave attenuation variation. The structure of the dynamic water level detector comprises a signal conversion body, a signal transmitter, a digital display screen, a sound wave attenuation detecting device and an embedded protection tube, wherein the signal conversion body is of a cylindrical structure, the signal transmitter is arranged above the signal conversion body and is electrically connected with the same, the digital display screen is embedded on the front surface of the signal conversion body, and the sound wave attenuation detecting device is arranged below the signal conversion body and is electrically connected with the same. By means of the arranged sound wave attenuation detecting device, the dynamic water level detector detects the water level in real time by utilizing the principle of sound wave attenuation variation based on the water level, especially can quickly and precisely detect the dynamic water level since the dynamic water level is based on material reflection waves, is less susceptible to external conditions in detection, and is suitable for water level detection under various conditions.

Description

technical field [0001] The invention relates to the technical field of water level detection, more precisely, it is a dynamic water level detector based on the change of sound wave attenuation. Background technique [0002] A water level detector refers to an instrument that can convert the water level parameter of the measured point into a corresponding electrical signal. It plays an important role in daily life and production. However, the water level detectors in the prior art have the following defects: [0003] The water level detectors in the prior art are greatly affected by external conditions when performing water level detection. For example, photoelectric water level detectors have higher requirements on water quality, and the detection results will be affected by the transparency of water. The detector will be disturbed by the water to cause inaccurate data, etc., so there is an urgent need for a water level detector that is less affected by external conditions. ...
