If you would like to know the EXACT amount of water remaining in your tank/s

consider a TOPARGEE digital display monitor.

Simple to install - battery/house/flushmount/recessed models available and they

are driven bu a small unit inserted into your supply line (after pump) and it will

count down from capacity to zero in 1- liter increments!

I have found it to be very accurate and trouble free now over about 6 years. (It

has had plenty of time to demonstrate reliabiliy since I use the van for about 4

months yearly).

Specially useful if you have an older van with basic ¾ - ½ - ¼ style displays.

Your current system is not interfered with and remains as a back-up.
