This H2F-FM RV Water Tank Gauge from Topargee monitors your tank level in litres so you know exactly how much water remains. Suits any number or size tanks, fitting in water line.
“Excellent and in my opinion an essential low cost addition to any RV with water storage.
Original install failed after a couple of years, but such a handy implement I did not hesitate to replace.”
“Meter work great, installation is very simple. However the instructions state to connect power at the pump since that's where the sensor will be mounted. Unfortunately, our pump causes the meter to reboot when it runs. I recommend selecting a different power source for the gauge. It draws very little power, though not exactly sure how much as the intructions are incorrect in that area (8ma display and backlight on, 3ma display on backlight off, but then it states 8ma sleeping. I guess its probably 0.8ma sleeping. Overall a great device but the backup appears to be from sales.”
