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

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.

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.

I got this to measure how much water I am using to flush the tanks in my RV. It seems to work fine, but if I stop the water flow then start again, it doesn't seem to read correctly or stops reading. Maybe I am doing something wrong. More time will tell

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.

It calculated the water usage precisely and it's very simple to use. Nice quality.

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.

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.

Really neat tool for evaluation sprinkler settings. Attach into hose and see exactly how much water you're putting down.
