Diivoo Water Flow Meter with 180° Removable Panel, 4 Measure Modes, ±5% High Accuracy and IP54, Measure Gallon/Liter Consumption and Flow Rate for Outdoor Garden Hose Watering, RV Water Tank Filling

Excellent to keep trace of how much water that you are filling up with & how water that you are prefilling the black tan with ( important to prevent poo pyramids ) very accurate and leak resistant. And for the cost, built well and functional will be adding a second one as a backt

I'm using this to meter how many gallons I use in my rain catchment system.I use 26 of the blue 55 gallon plastic barrels to catch all my water coming from the rain gutters.I use the captured water to do all garden hoses for lawn watering and pressure washing and emergency drinking water 🚰 potential, if it comes to that. I was curious how many gallons was actually using of the free rain water, instead of having to pay the city the exorbitant water bill rates. Thanks to this meter I have discovered, I use a little over 100 gallons a month that otherwise I would have to purchase from the city.

Great little Water Flow Meter. Easy to Set-up, easy to Install, and provides accurate reading levels (I used a 5 gallon bucket and tested it that way). I give it 5 out of 5 stars in all but one category 'easy to read' which I gave a 4 out of 5 but, overall, it's a 5 for my needs/use....in a stationary place off a water Pump line.I really like that doesn't have 'a lot of frills' - it's very straight-forward to use - essentially just scroll through the information screens by pushing the orange button on the face of the unit. I owned it for about two weeks and it has been raining 'cats and dogs' for a # of those days and it seems perfectly fine. I hope this review is helpful to you (refer to a few photos).

Used this all last summer on my RV to track how much water I’m putting into the fresh tanks and during back fills on the black and grey tanks. Just pulled it out after the winter and still works good. Can’t say that it is super accurate, but good to the half gallon.

I tested the flow meter with a 5-gallon water bucket and found that the ±5% accuracy is spot on. I made a minor adjustment to the flow metering (easy to do) and got the flow very close to the five gallons it measured. The meter comes with everything you need for proper operation and connection. I did not have any water leakage between the meter and water hose, even without using the included PTFE tape. I like that you can rotate (flip) the view of the meter's screen, which makes it easy to read while using. I plan to use the Diivo meter to confirm the amount of water in my travel trailer's freshwater tank.

Easy to use, and accurate enough for my use. I verified filling a bucket to the 1 gallon mark, and this read 0.99 gal.

Though advertised as measuring down to .3 gpm, when it was brand new, it would not operate below1.0 gpm. A few days later, it would not register flow at all. There is a plastic turbine inside that turns to register flow and a magnetic sensor in the display unit outside the water flow area counts its turning rate. That turbine apparently doesn't turn easily enough.Furthermore, after a few days in the sun, it would not turn on. I took the battery out and put it back in, and then it turned on.

Works just fine. Don't know how accurate it is since I have not attempted to calibrate it. Needed it to determine where my water flow was being restricted in home plumbing.
