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
LS1
0.3 metre
5 metres
LS1-10M
0.5 metre
10 metres
LS1-P
0.1 metre
10 metres
LS1-P-20M
0.1 metre
20 metres
LS1-R
0.2 metre
7 metres
T35
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.
