Please continue to Positioning your sensor before drilling any holes.
Positioning Your sensor:
Make sure that the sensor position is at least 200mm above the highest water level.
You will need to drill a 50mm hole in the tank.
The sensor should be as close to level as possible, at no more than a three degree angle. Mounting shims are available if your tank has a curved top.
Ensure that there are no obstructions directly under your chosen mounting position of the sensor such as ball cocks, inflow and outflow pipes.
The sensor should be as close to level as possible, at no more than a three degree angle. Make sure that the sensor position is at least 200mm above the highest water level. The maximum range of the sensor is 3.5m.
Once you've decided on the best position for the sensor you'll need to cut a 50mm hole.
This will give your sensor a clear view of the water in the tank and make it easier to measure the distance between the sensor position and the bottom of the tank.
Before you install your sensor you'll need to take some measurements so we can calibrate the sensor to your tank. To measure the height of the sensor position, feed the tape measure through the 50mm hole to the bottom of the tank.
Record the distance between the sensor position hole and the bottom of the tank.
2. Record the maximum depth of the tank (usually the distance from the bottom of the tank to the overflow outlet).
3. Enter the tank measurements into the app:
Select the home tab on the Waterwatch mobile app. Select your sensor and follow the on screen instructions to enter your tank measurements.
If you decide to add or change these measurements later (set later), you can select "Change Tank Measurements” in the sensor screen .
Otherwise, email the measurements to [email protected] as soon as possible and we will set them for you.
Attach your sensor to your tank using the supplied M4 screws. If you have a concrete tank, you'll need to supply your own concrete screws.
Mounting high (but off center) using the mounting shims is the standard method for installation on concrete tanks. Some customers prefer replacing the inspection lid with timber to attach the sensor.
The best installation spot is on the center of the tank roof. This is usually the highest point and allows a clear view to the water surface.
If the center of the tank is not flat, there are alternative options:
The sensor can be installed on the tanks access lid. This is not the best position as false alarms can be triggered if you happen to remove the tank lid for inspection.
As with concrete tanks, the sensor can be installed high (but off center) using the mounting shims for leveling.
