2 Pack - P3 P0550 Water Meter | Measure Watering Use in Gallons or Liters |Fits Standard Garden Hose

I picked these up with plans to revamp my watering system, and although it took me a while to get around to it, once I did, I enjoyed seeing my water usage with both of these.However, after the first year, I started to notice problems with one not measuring flow rate anymore, even though the battery was fine and the screen still lit up. The numbers just didn't increase.Then the other one started acting flaky, and neither one of them was recording flow, yet both still had power. (Update: that second one seems to be working again, for now, so I will put it back in the "flaky" category, not the "broken" category. The other one doesn't seem to want to play along, though.)Update #2: I am bumping this back up to five stars, because when I removed the one that wasn't working, I noticed that there was something caught in the tiny impeller blade that measures the flow, and once I cleared that out, it started working again just fine.It's not a very complex mechanism, it just has this tiny fan blade inside of it, and once it was clear, I could blow air through it and see the numbers increase. So, I once again recommend these, both are working, and if you run into any troubles, take it off and make sure you can spin the little fan inside. 👍

It works well

I checked the accuracy by filling a one-gallon milk jug several times. The meter indicated between 0.7 and 0.9 in multiple attempts when the jug was full, so I figure that whatever the reading is, figure that it will display only about 80% of the actual amount. That said, the documentation does advise that the meter is not to be used for any kind of instrumentation or process control. Your results may vary.

Great item for knowing how much water is going into your tanks.

2/17/18 - Just received this water meter for my RV outings. Tested it on a 1gal jug 3 or 4 times. It seems to be accurate each time. I gave 3 stars because, after testing, I opened up the battery compartment (even though there is an o-ring thereto seal the compartment ), water had leaked inside the compartment somehow. My suggestion, after each use, open the battery compartment and drain/dry out any water that may have breached inside. Also, you might want to put tape on the battery contact points to stop battery drainage while not in use (if you do not use it frequently). Only time will tell if it holds up. 6/14/18 *Update* DO NOT BUY....JUNK. Literally used 2 times...Once for testing to make sure it was accurate and it was. However, there was some water leaking into the battery compartment that I dried out and then stored in original packaging. The second time I used the water meter water was leaking from below the digital screen where it attaches to the meter body. When I say leaking water, I mean shooting at least 6 -9 pinhole size streams in ALL directions & major water in the battery compartment. I am outside of Amazon's return policy time limit. I will call the company because there is a 6-month warranty from date of purchase. AGAIN...SAVE YOUR MONEY6/15/18 *Update* Again, DO NOT BUY this water meter!! Called P3 International and spoke to customer No-Service. The gentleman was very rude and acted like he was annoyed. I was told to send an email to tech support along with my receipt asking for a replacement. After receiving an RMA #, I would then have to send THEIR DEFECTIVE product back to them...with no reimbursement for the shipping. When I asked to clarify the returning process, the Customer No-Service only became ruder a then hung up without saying a word. Annoyed, I then called Amazon to complain about the product, the company and customer service that they were working with. Amazon apologized and graciously gave me a one-time replacement of the product and offered to pay for the return shipping back to Amazon. Sadly, I have low hopes that this new replacement low-quality product will hold up either. PLEASE SAVE YOUR HARD EARNED MONEY AND SPEND IT ON QUALITY PRODUCTS FROM A GOOD COMPANY (NOT P3 International, IMO) WHO RESPECTS IT'S CUSTOMERS.

Helps to know when the fresh water tank is full and not rely on the over flow to let you know

Used it for RV. Seems to work fine. Accurate at 5gal fill and 60gal fresh water fill. Probably off by like 0.5 gal, but that's over 60 gal, so I'm okay with that.I saw other reviews about its sturdiness. While plastic may not be the strongest material, I don't see how this would break from using it like you're supposed to. Make sure you install it where you're not applying moment on the connection. An example is installing it where the gauge is sticking out at an angle or perpendicular to the faucet. Of course that's going to break eventually. Mine didn't leak. If it did, I guess you could fix that by lowering your water pressure or put a whole bunch of dielectric grease in the battery compartment to reduce corrosion. Also, if it leaks, check the rubber o-ring. Usually it's improper o-ring size/position. Tightening too much will also cause the o-ring (not just this gauge) to distort and no long act as a sealer. Just because it tightens, doesn't mean you should keep tightening it.I ran it at 60 running psi and 85 static psi. It held up just fine.

I bought this to monitor how much water I was putting in my RV water tank. I knew when I bought it that it was just plastic. The meter is spot on. I was extremely careful not to allow the weight of the hose dangle off the end. Really only used it a few times. Now it leaks where the female end attaches to the meter. Gonna try and one that’s a little more robust.

Easy to use and serves a purpose only it can-how much is going through the line!Came on time and of great value

The media could not be loaded.  Primero encendió pero la medición era incorrecta, luego encendió pero ya no había medición y por último ya ni encendió, dos dias de uso

The media could not be loaded.  Like the product but it does have a design flaw that impacts its readability - see video

El producto llego en tiempo y la factura también fue fácil de conseguir.

Didn't arrived at all, don't know why they ask me to write a review on this.India with love
