If you are relying on rainwater for irrigation around your home or perhaps for use inside your home, then you should be able to see how much rainwater you have in your water tank at any given time.
You may want to adjust the amount of rainwater you are re-using to make it last longer if you can see that the water level is dropping and you know that there is no immediate forecast for rain.
Traditionally, the way to work out the water level in a rainwater tank has been to either look into the top of the tank (or get under the house in the case of a bladder water tank) or to "rap" your knuckles on the side of the tank until you can guestimate where the water level is.
The old ways of determining water levels may not be convenient (depending on where your water tank is located) or safe.
There are now two options that address the issues of the old way of determining water level.
- wireless water tank gauges
- mechanical water tank gauges
Why you would consider a wireless water level gauge
Wireless water level gauges are really easy! You can check out the water level in your water tank from the comfort of your own home. You would consider a wireless water level tank if:
- your tank is in a difficult access location or a long way from the house
- you want the convenience of easily checking your water level at any time from inside your home
- you are keen to keep a close eye on your water level and rainwater use
Why you would consider a mechanical water level gauge
To read a mechanical rainwater level indicator you need to be relatively close to it. You would consider a mechanical rainwater tank level indicator if:
- your water tank is not too far from your house
- you are easily able to see a water level gauge located in the top of it
- you are looking for the cheapest water level indicator solution
