Technical principle: Static pressure measurement, accurate calculation of liquid level height

Dingjin high-precision liquid level sensor adopts the principle of static pressure measurement, and achieves accurate calculation of liquid level through the mathematical relationship between the pressure on the liquid surface of the sensor and the height of the liquid. When the sensor is placed into the measured liquid, the pressure on the liquid surface is determined by the liquid density, gravitational acceleration, liquid level depth, and atmospheric pressure on the liquid surface. By introducing liquid pressure into the positive pressure chamber of the sensor through gas guiding stainless steel, and offsetting the back atmospheric pressure, the sensor directly measures the liquid static pressure, which is then converted into liquid level height. This principle ensures the accuracy and stability of measurement results, and can maintain high-precision output even under complex working conditions.
