THE 5-SECOND TRICK FOR ULTRASONIC LEVEL SENSOR

g.H+Po, in the method P may be the tension over the liquid surface in the sensor, ρ could be the density of the liquid for being calculated, g is definitely the regional acceleration of gravity, Po would be the atmospheric strain over the liquid surface, and H could be the depth at which the sensor drops to the liquid.S (Signal) pin: is undoubtedl
