The perfect tank monitor for your waste tank whether it is in metal or plastic. LEDs of different colors show four levels; empty, 1 / 4-, 1 / 2- and 3/4-full. 3 sensors mounted (glued) with a 3M adhesive tape on the outside of your tank.
It is very easy to retrofit onto both old and new tanks. Fully automatic installation ensures that usually does not take more than 30 minutes to install. It could not be easier!
A simple system for overflow protection, which prevents you from inadvertently filling your waste tank, that is, it tells you when the tank is 3/4-full and the toilet can’t be used until the tank is empty again.
Only one sensor is attached to the outside of the tank.
