Off - The sensor will not transmit any measurements to your mobile app including alarm alerts.
Measure and enter distance from the sensor to the tank bottom and then select next. Then enter the maximum possible water level which is usually the distance between the overflow outlet and the bottom of the tank.
The offset of a sensor is the distance between the sensor and the baseline water level. The baseline is the water level that you choose to define as 0. The sensor can calculate the height of the water using the distance to the water surface .
