Keep track of how much water you have left in the tank! The easy to install and use system from Topargee, allows users to quickly and reilably check how much water is left in their water tanks. The H2F-SM Water Tank Gauge counts down litre by litre from a preset amount to eliminate guessing what is left in your water supply.
