P3 Water Flow Meter with Reversed Display for Reading Gallon Usage from an Outdoor Garden Hose | Great for Campers and Boats | Helps Conserve Water

Works great for what I needed and the price was actually not bad for what it is if you’re looking for something like this.

A good way to know how many gallons of water you have in the tank. Or how much you used

The media could not be loaded. Update: Of the 3 flaws i mentioned previously I was able to "resolve" 2 of them. The shut off feature worked eventually but it was not 30 seconds. The accuracy issue was resolved by having the meter in-line. The inaccuracy I was experiencing was a result of the meter being right before a quick-disconnect fitting. Once the meter was placed in a location where flow was undisturbed before and after (in between two hoses) it was more accurate. This is not the same as the pictures showing its use connected right before a sprayer. It still leaked though so I still sent it back. Previous review: I just purchased this hose water meter and used it right away to fill my travel trailer fresh water tank. In less than 1 hour of use, I discovered three flaws: 1) Inaccurate. My trailer tank is a nominal 45 gallons, I suspected it was a little bigger. I was surprised to see the meter indicated a 68-gallon fill (before I saw flow out of my overflow tap). This made me suspicious. I conducted a test with a gallon pitcher, I confirmed the pitcher capacity with a quart measuring cup. the meter indicated 1.3 gallons twice, 1.4 gallons, and 1.2 gallons on 4 separate consecutive tests. 2) Leaks. When connected to the trailer, it leaked on the outlet-side of the meter, confirmed the leak by capping the outlet and just having it connected to the hose. it was a fast drip leak and I need a product that will not leak as I intend to leave this connected to my water supply on the trailer when I am using city water. 3) Erroneous description. There is no auto shut-off as indicated in the instructions and product description. The meter is to shut off after 30 seconds of no flow. The meter was on when I opened the package, and never turned off, even after an hour of no flow. I do not need to keep a stock of batteries on hand just for this meter. I was tempted to return and replace it, but I think I will just send it back and look for a better product.

I have several of the original flow meters and have never had a failure. I use them on the hose end attached to equipment not at the spigot, so the screen has always been backwards. Love the new reversed screen. I have this one mounted at the inlet to the camper.

Love this product. It really helps when flushing rv tanks to monitor how much water you are putting in to your black tank

This helps me see how much water I am putting in my holding tank for my motorhome

This is great for the slip tank on my husbands truck. Now we know how much fuel is on board.

This does not even time out after 2-minutes of no water flow. The battery will be used much quicker than the other more popular model. I had the original model and it did timeout after 30-seconds.

Ordered, but something happened during transit, did not find out reason it was 9 days past the original date that I waited. So I ordered another one from different seller. I submitted my case for refund, and later the same day…it arrived in my mail? I communicated that back to supplier thru Amazon, but was told not available. It works just fine though, drips a wee bit, but I also have the second one also now.
