Description

Technical Field

[0002] A water level meter, also called a liquid level meter or liquid surface meter, is an instrument that automatically measures and records the water level of rivers, lakes, irrigation canals and other water bodies. There are many types of water level meter products, and commonly used ones include glass level gauges, pressure level gauges, buoy level gauges, capacitance level gauges and resistance level gauges. Currently, the most widely used in water level monitoring is the pressure type water level gauge. Its principle is to put the sensor into the water, and the component detects the pressure of the water acting on the sensor, and then calculates the water level value through air pressure, density, sensor placement depth, etc.

[0003] The utility model with Chinese patent application number CN201620105514.8 discloses an immersion-type microwave monitoring water level meter. The utility model calculates the water level depth to be detected by the propagation time of the pulse signal in the first waveguide cable and the second waveguide cable. This detection method is not affected by the changes in water density and air pressure, and has high detection accuracy, good stability and long service life. The bottom ends of the first waveguide cable and the second waveguide cable are connected to a heavy hammer, which can ensure that the cables are straightened in the water, facilitate the lowering of the first waveguide cable and the second waveguide cable, and make the detected water level depth more accurate;

[0004] However, when the structure is actually used, due to the presence of algae, floating objects, microorganisms and other impurities in the water, these floating objects are easily attached to and entangled in the device during use, and the long-term existence of these floating objects has a significant impact on the use effect of the device.
