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 | |
