moistenlandWater Flow Meter, Standard 3/4" Hose Thread, High Accuracy and IPX6 Waterproof, Water Meter for Garden Hose/RVs

Very accurate. A must for back flushing your RV tanks. Batteries last a long time and are easy to get (Walmart).⭐️⭐️⭐️⭐️⭐️

Excellent product. Love it that it’s in gallons and that it’s connectors or plastic so they do not weld to the hose.

We use this when filling our water tanks at marinas. I like to see how much water we are purchasing and it also prevents us from overfilling our tanks (as our gauges no longer work). It’s a great item - small and a great price!

This is the second flow meter I've purchased. My first one was pretty simple. Two readings, one for current usage and one for total usage. Easy to understand. I purchased this one for my RV. My first use and I thought it was broken. Then I started fooling with it more and found the current use setting. It appeared to be accurate, but there's all the other settings that I found difficult to separate out. I'd say, if you are looking for all the possible measures of water flow, this is the meter for you. If you're just looking for how many gallons you just used or total you used, you might consider a simpler meter.

I use this to flush out and fill the black tank on the RV trailer. I like to roll with 7 gals in the tank and this thing gives me an exact amount instead of me guessing. very solid unit.

Use this to monitor the amount of water put into my RV tank.

This unit does measure water going through it, but it reduces the pressure, and volume big time. I have a shallow well that pumps up 60 pounds of pressure and pumps up 12 gallons a minute. I use a spray wand that sprays a solid stream about 12 feet. When I installed this unit, the spray only went 6 feet at most. I wanted to see how many gallons I use to water my lawn, but this changes the output of my well so much that the readings are not going to be even close to what my well produces.

I bought this primarily to track water usage in my travel trailer when we're hooked up to city water. I've been using it for a couple of weeks, and all looks good. It appears to be accurate - I checked it against a 3-gallon water bottle, and it was spot-on. Having the flow rate is also useful, because when we need to use the tank (no city hookup), if I fill it too fast it overflows (air getting trapped, I think). Now, I have been able to see what flow rate works and I can just set it to that. When I need to fill the tank I can just set it and forget it for a while, because I know it won't back up and I can time it to get the right amount of water in there. Overall, very happy.
