This gauge differs from conventional water gauges as it actually measures and displays how many usable litres remain in your tank. This is achieved by first filling the water tank, then using it as usual until empty, then the precise number of usable litres will be known. This figure is then programmed into the H2Flow which will measure every litre that flows out of the tank and calculate the amount remaining. The LCD screen will display the number of litres left in the tank every time a tap is used or the unit Display button is pressed, so you will never be left unsure!
Whenever you refill the water tank all you need to do is press the reset button and the gauge will revert to the original quantity set.
The H2Flow can help travellers plan ahead for their journeys by enabling them to check the average number of litres used each day. Travellers can then calculate how many days they will get out of one tank or if they are already on their journey, look at the remaining litres to determine how many days supply is available. This is a valuable safety feature, especially in remote areas, as you will know if you need to conserve water or will safely make it to your next destination. It is also a handy way of ensuring you won’t run out of water mid-shower!
Another advantage is that nothing is fitted to the tank. The sender unit is fitted in the hose line, just before or after the pump. This removes the problem of having to remove the tank, drill holes, remove filings, seal sender holes, ongoing cleaning/maintenance, etc. There is even no need to connect to a 12v electrical system as the unit lasts up to 2 years on the AA batteries supplied. The LCD screen even displays a symbol and emits a warning buzzer when the batteries are running low.
The H2Flow simply couldn’t be easier to use. Since releasing the product, feedback has been very positive with comments like, “it’s great knowing how many litres I have left” or “how many days supply are available” “Received it today, fitted it today, works great!”, “it was cheaper and easier to fit this than repair my old gauge”
