Geevon Garden Hose Water Flow Meter with Brass Inlet Metal Thread, High Accuracy & IPX6 Waterproof for Outdoor Garden Watering, RV Water Tank Filling, Lawn Sprinkler, and Nozzle Sprayer (2 Pack)

Using these to monitor water usage on my camper trailer. Four months of full-time RVing. Previous ones lasted three weeks due to rain water getting into the electronics.

Well made, seems accurate, simple interface, good value. I have not used it long enough to comment on battery life. Only thing that I can think of that would make it better is if they added the functionality to flip the display. I use it on the end of the hose but have no trouble reading numbers upside down if I need to so it isn't an issue for me.

I use this to fill the freshwater tank of my travel trailer. It is especially useful for filling an empty tank before a trip because you can estimate you trip needs (for short trips) and not overfill, saving weight. I have not benchmarked the accuracy of the flowmeter so don't know that, but at least it now provides a good guideline.

Pretty accurate, helps us to know when our fresh water tank is almost full. Battery lasts for an entire camping season and is easy to replace. Helps take the guesswork out of filling your tank.

This works fine for measuring how much water you've used. Very convenient.

Works well for measuring water when filling my (hidden) fresh water storage tank and when filling and flushing the wastewater tanks on my camper. Easy to use, comes with battery and battery cover tool.

I wanted to track my water usage for my diy sprinkler system. If you have done your own system, you know flow and pressure from the spigot is important. Well- bought one of these to test and my diy system worked perfectly with this attached at the hose spigot. It doesn’t restrict flow and I can get a snapshot of total usage and single usage. Bought another one.
