RESTMO Water Flow Meter, Measure Gallon/Liter Consumption and Flow Rate

I picked up this RESTMO water flow gauge to use with my camper van, which has a 30 gallon freshwater tank, and it has been an excellent addition to my setup. My main goal was to avoid overfilling the tank while still knowing exactly how much water I was adding, and this gauge does that perfectly. Installation could not be easier. It screws right onto a standard garden hose and then onto the camper inlet with no leaks or fuss. It comes with a coin style battery already included, so it is ready to use right out of the box. Once water starts flowing, the screen turns on automatically, which is very convenient. When the water stops, it shuts itself off, so there is no need to worry about draining the battery. The accuracy is what really impressed me. I filled my tank multiple times and the gallon count has been consistently spot on. Knowing exactly how many gallons are going in lets me stop filling before the tank reaches capacity, which saves water and prevents messy overflows. This is especially helpful at campgrounds where water pressure can vary. Resetting the gauge is simple. You just hold down the green button for a couple of seconds and it clears the count, making it easy to start fresh for each fill. The display is clear and easy to read, even in outdoor lighting. Overall, this water flow gauge works very well and does exactly what it claims. It is accurate, easy to use, and extremely practical for camper van owners. I really like this product and would recommend it to anyone who wants better control over their water usage.

I bought the RESTMO Water Flow Meter with the brass inlet and outlet specifically for my camper, and it’s been a really useful addition. I use it when flushing my black tank so I can see exactly how much water I’m putting in, and it takes a lot of the guesswork out of the process. Great value for this item and compatible with any hose connection I believe. The brass fittings are solid and feel high-quality—no leaks and much more durable than the cheaper plastic ones. The display is easy to read, and it tracks water usage accurately enough for what I need. It’s especially helpful to avoid overfilling while still making sure I’m flushing thoroughly. Setup is simple—just connect it inline with the hose and you’re good to go. It’s one of those small upgrades that makes camper maintenance a lot easier and more controlled. Overall, I’m really happy with it. If you’re flushing tanks or just want to monitor water usage at your campsite, this is definitely worth it.

Works well. Accurate water usage. Easy to use but you can’t change how the numbers display. It is easy to read. I had it for a few month and battery is still full

Perfect for our trailer. Monitors water usage with ease. No leaks.

This meter seems to work well and gives a accurate measurement. Need to get a few month usage before fifth star given.

Still works on the same original battery after a year of heavy use

Setup and first use…. The battery (a button battery) was hard to seat in the battery compartment. The contacts are small and the battery is not supported well so it moves around while you are screwing the cover on. It took a couple of tries to get it in correctly so the metal leads made proper contact. The first time I set it up, it worked fine. Used it for about a week, continuously with a pool fill shutoff to keep my pool filled and it worked fine. Then I stored it indoors for about 2 weeks. Second use….. Took it out of storage and it does not work. I can see there is water inside the LCD screen. Surprisingly the unit is not waterproof and water must have made its way inside and shorted it out somehow. Tried drying out as much as I could and replacing the battery, but it still does work. I’m still within my 30 day return window and will see if they take it back. I would count not being waterproof a defect.

It works as advertised. No more guessing how much water we’re putting in our RV. Easy to use

Quality product and seems fairly accurate; did a calibration test and volume was reasonably close to measured. Highly recommended for setting watering volumes for new shrubs.

Nice unit. Easy to use. Solid design. Happy with the purchase.

Love these meters, I've gone through 3 or 4 of them but it's not because they are not well made, they are, we just use them in a very busy commercial setting so they get beat up a lot and honestly last longer that they should given the abuse they see, being dropped subjected to hot temperatures and sometimes run upto 1000L per day. Solid sturdy reader, highly recommend.

Works wrll

Has a few functions, reasonable price. Like the brass fittings.
