Working principle

The static pressure of a point in the liquid is proportional to the distance from the point to the liquid surface, namely :P ~ the pressure of the measured point (pressure), ρ ~ medium density, g ~ gravitational acceleration, h ~ height from measured point to liquid surface

For the determined measured medium and location, ρ g is a constant, so the change from the measured point to the liquid surface is only related to the measured pressure (pressure).

WIDEPLUS-L series static pressure level transmitter is to determine the liquid level position by measuring the static pressure of the measured point.
