Question

Are there any precautions for using E4PA Ultra Sonic Displacement Sensor to detect the liquid level in a tank?

Answer

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.)
