1. Installation height: Set the distance from sensor to tank bottom A；

2. Liquid maximum depth: Maximum height of liquid in tank;

3. Set Max: Set Max for high level alarm (Actual liquid level value B);

4. Set Min: Set Min for low level alarm;

5. Sensor ID: Gateway link sensor’s ID, default is linked; To re-link another sensor, write the ID of the new sensor;

6. Beep Alarm: Turn on/off the device alarm sound.

Hold the sensor perpendicular to the liquid

Install the sensor away from the water inlet to avoid pseudo-echo

The sensor installation cannot be close to the bulkhead, otherwise it will cause a strong pseudo-echo
