  Note 1: The density of the measured medium needs to be provided in meters, the principle is as follows The formula for the
pressure of the sensor facing the liquid surface is: Ρ=ρgh + Po formula: P: The pressure of the sensor facing the liquid surface (for ease of understanding, hereinafter collectively referred to as pressure) ρ: Measured liquid density (default 1g/cm³ during debugging) g:
Acceleration due to gravity (default 9.8m/s² during debugging)

 

Po: atmospheric pressure h on the liquid surface: the depth at which the sensor is inserted into the liquid When the sensor is inserted into a certain depth
in the measured liquid, the pressure of the measured medium is introduced into the positive pressure cavity of the sensor, and the
atmospheric pressure Po on the liquid level is connected to the negative pressure cavity of the sensor through the cable air pipe to offset the Po on the front of the sensor, so that the pressure measured by the sensor is: ρgh, obviously, by measuring the pressure
P,
The level depth can be obtained.
