2 Inch Digital Turbine Flow Meter, 15.8-132 GPM Inline NPT Thread Fuel Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³

Used it with water to gauge tanks. Accuracy is good enough out of the box, it was within 3 gallons on a 1000 gallon tank so I didn't even bother to calibrate it for accuracy. Ran it consistently at 10-12 gpm.

I used this on the discharge of my cottage pump to flow/pressure test it after I rebuilt it. Worked great. My pump curve matched the curve from the pump manufacturer (Franklin FVJ05CI ½hp pump). I also measured the current, voltage, power, and power factor with a meter I got from Amazon. I will be permanently installing the flow meter on the discharge when the pump goes back in next spring. I didn't use the 3/4" adapters and would probably just use a real pipe bushings if I needed 3/4". The o-ringed adapters suppliex are a bit questionable.

Great product. Comes with adapters to hookup to 3/4 or unscrew the adapter and it's 1 inch threads. Works great love it.

Good product works awesome did not check how accurate it is but it's good enough to load the sprayer
