Sprinkler truck water volume sensor/water volume monitoring device:

The water level sensor monitor of the sprinkler truck 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.

Functional features:

Good stability, with a long-term stability of 0.1% FS/year at full and zero positions. Within the compensation temperature range of 0-70 ℃, the temperature drift is less than 0.1% FS, and within the entire allowable operating temperature range, it is less than 0.3% FS. Equipped with reverse protection and current limiting protection circuits, the transmitter will not be damaged if the positive and negative poles are reversed during installation. In case of abnormalities, the transmitter will automatically limit the current to within 35MA. Solid state structure, no movable parts, high reliability, long service life.

Easy to install, simple structure, economical and durable.
