In recent years, we often see some of the groundwater level drop caused by the collapse of the road, so the groundwater level monitoring is now an important part of the environmental testing. Liquid level sensor is the right hand of water level monitoring, and input level sensor is the most important kind of liquid level sensor, most of the cities and regions of groundwater monitoring use input level sensor. Installation of pressure sensors The input level sensor adopts diffusion silicon piezoresistive core and stainless steel structure. Input level sensor is mainly applied to the water level overflow weir, pumping station, liquid tank level measurement, water treatment plant, water circulation and other level measurement and control. Input level sensor diffusion silicon pressure sensitive element diaphragm isolation technology, cable connection, directly into the field, easy installation, amplification circuit using integrated chip, wide voltage power supply, anti-clogging, anti-scaling, anti-lightning strike, cut-off frequency interference design, anti-jamming ability, wiring reversal and over-voltage protection, current-limit protection (limit current output), good stability, fast response speed. When the input level sensor is put into the measured liquid at a certain depth, the level sensor meets the liquid surface by the pressure formula: Ρ = ρ.g.H + Po where: P is the level meter meets the pressure on the liquid surface, ρ is the measured liquid density, g is the acceleration of gravity, Po is the atmospheric pressure on the liquid surface, and H is the depth of the level sensor into the liquid. At the same time, through the air-conducting stainless steel will be the pressure of the liquid into the positive pressure chamber of the sensor, and then the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the liquid level sensor, so that the sensor measured pressure: ρ.g.H. Obviously, through the measurement of the pressure P, you can get the depth of the liquid level. There are many kinds of input level sensors, why input level sensors are suitable for groundwater level monitoring, which is mainly and its characteristics have a lot to do with the input level sensors are easy to install, stability is guaranteed, so suitable for a wide range of applications, and now a lot of cities in the groundwater monitoring are used in the input level sensors.
