Overview

Input type liquid level gauge: The static pressure at a certain point in the liquid is directly proportional to the distance from that point to the liquid level. Liquid level formula: H=P/pg; Among them, H is the liquid level height, P is the pressure at the measured point, p is the medium density, which is a constant, and g is the gravitational acceleration, which is a constant. Therefore, the position change from the measured point to the liquid level is only dependent on the measured pressure. This principle is adopted by the series of liquid level transmitters.
