Are there any precautions for using E4PA Ultra Sonic Displacement Sensor to detect the liquid level in a tank?
1.Make sure that the E4PA is far enough away from the walls.
2.If the upper part of the tank is narrow (cylindrical), expose the sensing surface or make it into a horn shape.
3.Make sure that there are no objects protruding into the operating range of the Sensor.
(Otherwise the protruding object will be detected.)
