Question

E4PA Ultrasonic Sensors will be used to detect liquid levels, but it is difficult to move E4PA up or down when installing it. Is there an easy way to set the distance?

Answer

Using E4PA with the default settings is recommended. The rated minimum distance and rated maximum distance are already set. Setup can be completed simply by setting scaling for analog values (setting desired values for analog values such as 4 to 20 mA) using Digital Panel Indicators.

The resolution, however, will be (Maximum distance - Minimum distance)/4096.
