RESTMO Water Flow Meter with Brass Inlet & Outlet, Measure Gallon/Liter Consumption and Flow Rate for Outdoor Garden Hose Watering, RV Water Tank Filling, Lawn Sprinkler and Nozzle Sprayer

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 do a lot of RV camping and always need a reliable water meter to gauge how much water I'm putting into my fresh-water tank or how much water I've put into the other RV tanks. This thing is well built, sturdy, accurate (very important) and reliable. The LCD screen is easy to see for those who have close-up reading issues. The connectors are made of brass, so there is no chance of rusting. And if you need to adjust the screen so that's it's easier to read, no worries, the rotatable control panel makes so that you change the orientation of the screen. Cool! And since it's weather proof, you don't have to worry about leaving it hooked up to your hose. I highly recommend the RESTMO Water Flow Meter.

Works perfectly, now I know how much water I put in my black tank to flush it

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.

I bought this as I have a fifth wheel with a 98 gallon fresh water tank and I don't want to fill it completely on shorter trips. Have used this a half a dozen times now and been having varied results, all not good. From not counting gallons correctly (water was coming out the overflow on the camper while only showing 75 gallons) to just stop counting while I'm filling up. I bought this as it had good reviews but wanted to share my experiences for potential buyers. Update- a rep from Restmo reached out to me after my review, she credited my purchase and sent a new unit at no charge. I have now used this on 4 different RV trips and the new unit working well with no counting issues and doesn’t leak like the one(something I didn’t note on original). I must’ve gotten a defective counter, the company stepped up and I am now happy with this purchase.

This item works well when filling water into our fifth wheel camper fresh water tank. Water weighs about 8lb to the gallon. When we travel in our camper I like to carry some water in case of an emergency or to wash your hands or use the toilet. So I can monitor how many gallons of water I transport. Instead of hauling 81 gallons of fresh water I only fill my tank with about 15 or 20 gallons of fresh water and I know that it is potable all made possible with this water meter.

This water flow meter is easy to use and very well-made. I had a question/issue (it was actually my “user error”), and the company responded super quickly to my email (and were friendly). I’m so grateful!

This is a great tool to keep Track of outdoor water usage from the garden hose. One cans see usage separate from the indoor water use.

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.

The item came in good shape and works great.

the meter is very well built and comes with battery ,would recommend this.

Dead easy flow monitoring for RV tanks and garden sprinkler calibration. Put the battery in, connect and start metering. Flow rate, total, etc in imperial and metric. Instructions included, great construction, now permanently attached to my RV's fresh water hose. Essential equipment, highly recommend this easy to use version.

Excellent product
