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!

this works perfect. When you are flushing your toilet. No guess work. So easy to use

The device works well, but in hindsight, I would’ve put 3-4 feet of hose at the end of mine because when my device got wet, it stopped working— not a good feature for something intended to be used around water.

Works great when bagging concrete

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.

Didn’t think I would really use it, it’s nice to know yep there is ten gallons in the tank. I have a 50 gallon bladder in the bed of the truck. It reassures me I got 30 or 40 gallons of water in the bladder. Takes the guess work out of it.

I use this RESTMO water flow meter when flushing our RV’s black and gray holding tanks, and it has been incredibly helpful. It’s very easy to use—just connect it inline and start monitoring water flow. Being able to see exactly how many gallons are going into the tanks gives real peace of mind and helps prevent overfilling, which could otherwise lead to a messy and costly problem inside the RV. The brass inlet feels solid and well made, and the display is clear and easy to read. It’s one of those simple tools that quietly does its job but adds a lot of confidence to the process. I wouldn’t flush our tanks without it now and would highly recommend it to any RV owner looking for better control and safety during tank maintenance.

this works well, cannot attest to it's accuracy, but as a guide for what i'm doing(setting proper flow rates for my drip irrigation), it does the job.

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

Compacte et solide. Je suis satisfait.

Good toy, added to so many other toys. I bought it to get an idea of how much water I use for my tomatoes (try to figure the cost geting them from my garden - hahaha!). Also, the see how much water I fill in my RV water tank. As I said, use a good tool as a toy!

We use it to fill the black tank on the trailer when flushing, so we don't overfill. Seems to be accurate.
