Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water level observation, and in particular relates to a double-tube buried pressure water level gauge. Background Art
[0002] The pressure water level gauge is made of advanced isolated diffused silicon sensitive elements. It can be directly put into a container or water body to accurately measure the height from the end of the water level gauge to the water surface, and output the water level value through 4-20mA current or RS485 signal. Pressure water level gauges are widely used in water level monitoring fields such as urban water supply and drainage, sewage treatment, groundwater, reservoirs, rivers, and oceans.
[0003] The existing double-barrel buried pressure water level gauge still has some defects. During use, most double-barrel buried pressure water level gauges sink to the bottom of the water.

For this reason, we propose a double-barrel buried pressure water level gauge. Utility Model Content
