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

I’ve never used one of these before so I don’t have anything to compare it with, that being said for the price this seems like a really nice unit. I’m using it to measure the amount of water flow through my portable 8000-grain water softener, and it works great and feels decently well built. It has a handful of useful features, including the two most important features for me, which are: it keeps memory of total gallons between battery changes, and it automatically turns on when it detects water flowing (I know that I’d forget to press the on button half the time, thankfully not required!). I haven’t done any detailed accuracy tests, but it seems quite accurate, and is certainly good enough for my needs. It states that it’s accurate within +- 5%

I've always wanted to track the amount of water I'm putting into my rv. Not just the fresh tank, but the 5 or so gallons I like to put into my black tank before using it. Prevents piling. This little device finally enabled that and made it easier than filling a bucket and pouring it into the toilet, or sitting there counting the minutes and seconds trying to determine how much was going in thru the pressure regulator. Our pressure where we live varies. So far, it has been reliable, accurate, was easy to connect, and appears to be well made. They even gave me a plastic 'coin' to open it and install the battery that they supplied. It doesn't leak and is easy to operate AND read. It even shuts itself off after a period of time when it isn't being used. You know, like after you shut off the water but still leave the hose connected? 5 stars for me!

Great way to know exactly how many gallons you're putting into your RV fresh water tank. It's all about weight. Works well , easy to read.

Great way to know how much water you have used when filling a tank or at an RV campsite.

Works well and after some testing is pretty darn accurate. Comes in handy, knowing how much water has been used when flushing out the tanks in our travel trailer is great info.

I have been using the RESTMO Water Flow meter for over a year on my RV. Excellent for measuring water flow and total gallons when dumping and flushing tanks. Changed the battery once, easy to do. Has worked awesome. Great product will purchase again.

This water flow meter is one of those tools I did not know I needed until I had it. I use it when washing my truck so I can see exactly how much water I am using. Sounds simple but it is actually really useful for tracking consumption and being more efficient with my wash routine. No more guessing or wondering if I left the hose running too long. The digital display is clear and easy to read even in direct sunlight. It shows gallons used in real time so you can monitor as you go. I like knowing the numbers because it helps me be more conscious about water usage. Plus it is just satisfying to have data on something you do regularly. Information is power even when it comes to washing your truck. The brass inlet is a nice touch. Plastic fittings on hose accessories always feel cheap and tend to crack or strip over time. Brass holds up better and gives me confidence this thing will last through seasons of use. It threads onto the hose smoothly and seals well without leaking. Build quality overall feels solid and durable. Setup takes about thirty seconds. Screw it onto the spigot, connect your hose to the other end, and you are ready to go. The meter sits inline and does not restrict flow noticeably. Your hose pressure stays strong and the meter just quietly does its job tracking usage in the background. Battery life seems fine so far. It uses a standard battery that is easy to replace when the time comes. The display has been consistent and accurate based on my rough estimates of water usage. I have no reason to doubt the readings and they match up with what I would expect. For anyone who wants to track water usage on outdoor tasks, this is a great little tool. Washing vehicles, filling pools, watering gardens. Whatever you are doing with a hose, this tells you exactly how much water you are putting down. Useful information that helps you be smarter about consumption.

The product does not work. I was unable to use it initially as we had illness. When I was able to use it, it was 6 days past the return date. I called Restmo three times and left a message but did not receive a call back. It is impossible that it would not work at all. I am really disappointed with their customer support. Restmo has contacted me and is replacing the water flow meter. I am looking forward to receiving it as if it functions as advertised it will be exactly what I am looking for. Thank you Restmo!!

Worked perfectly.Just a tip if your using quick connectors the male end has a grey plug in the unit.Do not remove or it won’t work properly.You will need to trim the outer lip of the quick connector where it mates up to the male end.You'll soon find out when you try to screw it on.The grey plug of the unit is in the way.Just again trim the inner lip where it mates up when screwing it on & everything will work fine.

Out of the box the unit looks quality built; unfortunately, it only reads in gallons; kind of inexplicable why the input connector is brass and the output male connector is plastic which did not squarely fit any of my either plastic or brass female ends; stripped the plastic thread a bit and the female end did not squarely fit though I torqued it down and used teflon tape to seal

Great product! Use it daily for now my second summer. Tanks in RV’s are never accurate this allows me to take exactly what i need vs always “filling” the heavy tank. Allows me to take just what i need for the days i need to be dry camping.

This gauge works great! Easy to reset, easy to read, very durable. Works well to control your trailer weight on long trips!

.......if you are going to attach a hosepipe to it, which you will probably want to do, you will need one of these.. Hot Tub Drain Valve Adaptor.... https://www.amazon.co.uk/dp/B0CYQJK4VT?ref=ppx_pop_mob_ap_share This is because the thread on the meter is not UK spec. It WILL leak without this part. There was no mention of this in the product listing otherwise it would have got 5 stars
