Description :

　　A pressure type water level gauge is a water level gauge that uses pressure-sensitive components as sensors based on the principle of hydrostatic pressure, which is proportional to pressure and water depth.

　　Working principle of pressure type water level gauge

　　Its working principle is to measure water pressure and calculate water level. Its characteristic is that it does not require the construction of static water logging, and the sensor can be fixed at the bottom of the river to eliminate atmospheric pressure with a pressure pipe, thus directly measuring the water level.

　　The pressure type liquid level gauge adopts the principle of static pressure measurement. When the liquid level transmitter is put into a certain depth of the measured liquid, the sensor is subjected to pressure on the liquid surface. At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the gas guiding stainless steel. 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 sensor, so that the pressure measured by the sensor is: ρ. g.H. By measuring the pressure P, the depth of the liquid level can be obtained.
