Valid Sensor Ranges
How far/close can my sensor measure
Waterwatch sensors have limitations in the measurement distance. If the sensor is too close or too far from the surface, the sensor is not able to record a valid measurement. Different types of sensors usually have their own minimum and maximum ranges.
Sensor model
Min distance from surface
Max distance from surface
0.3 metre
5 metres
0.5 metre
10 metres
0.1 metre
10 metres
0.1 metre
20 metres
0.2 metre
7 metres
0.2 metre
3.5 metres
Please note that the distance is calculated from the sensor module (not the device) to the surface. For example, for T35 sensors, the sensor module is at the bottom of the sensor; for LS1-P sensors, the sensor module is the cylindar metal piece, attaching to the end of the cable.
