Rain Harvesting Tank Gauge
Use the Rain Harvesting Tank Gauge and accurately monitor your rainwater supply with this easy-to-read, tank-top water level indicator.
Measure stored water at a glance
The Tank Gauge helps you make better water usage decisions by revealing how quickly your water supply is replenished during rainfall events. Its easy-to-read dial face features “Empty” and “Full” indicators to offer a more meaningful measurement than numbered dials.
Monitor your water consumption
By tracking and understanding how much water you use for different activities, you can take the necessary steps to avoid unexpected shortfalls and make your rainwater supply last longer. You may even learn you can use more water than you thought!
Install and maintain with ease
The Tank Gauge can be easily sealed directly to your tank. With no batteries or wiring and a straightforward, mechanical design, it requires next to no maintenance and is suitable for all vented aboveground and belowground tanks up to 2.5 metres / 100 inches in height.
Installation
- Select an installation point on top of your tank for your Tank Gauge. Ideally, this should be a flat area that will allow you to view the gauge face easily. Mark your chosen installation point.
- Use a power drill fitted with a 32mm (1.25″) spade bit or holesaw to create a 32mm (1.25″) hole in your tank at the marked location.
- Carefully remove the front clear cover from your Tank Gauge with the edge of a flathead screwdriver or 5 cent piece (nickel) to enable access to the moveable empty and full indicators
- Note: Steps 5-10 are more easily accomplished with two people working together.
- Have one person hold the base of your Tank Gauge at the height of the previously drilled installation hole and have the other person lower the float until the top of the float is level with the bottom of your tank overflow outlet. If your overflow outlet is not near the installation site, measure down from a known common point on the tank and use this measurement to set the float as described.
- Move the green “full” dial/indicator to where the black water level dial/indicator is pointing.
- While one person continues to hold your gauge in place as described in step 5, have the other person lower the float until the top of the float is level with the bottom of your tank pump outlet.
- Move the red “empty” dial/indicator to where the black water level dial/indicator is pointing.
- Replace the front clear cover.
- Retract the string and float to 90% level. Pinch the string with your finger against your Tank Gauge body to prevent the string retracting any further.
- Bring your gauge and float up to the installation hole and lower the float through the installation hole until it rests in the water. Position the gauge body in and over the installation hole.
- Position your gauge so that the “full” and “empty” indicators are clearly visible from the ground.
- Using the supplied screws, secure your Tank Gauge to the top of your tank.
