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)

Worked Perfectly, nice to have on hand!!

I have always wonder about water flow and usage at times. I was very surprised to learn I have a flow rate of 4.8 gal a min at the utility sink in the wash room. I'll be able keep an eye on water usage while watering my garden.

C+

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.

definitely helpful in monitoring water pressure at various RV parks and in tracking the amount of water adding to a tank.

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.

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.

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.
