1 Inch Digital Turbine Fuel Flow Meter, 2.6-26 GPM Inline NPT Thread Flowmeter with 3/4 in Adapters for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³

This is a very impressive meter. A similar meter at our local Fleet Farm was selling for $159.

Fantastic product. Made with good precision and finese. Best value for money.

Product is of cheap quality. After one week of use I had to replace batteries, upon doing this I determined housing was full of water from unit not being factory sealed properly. Also any little of fuel hose triggers it to read volume, probably why batteries only lasted one week. Product may be good for out of the weather use but wouldn’t recommend for outdoor use on diesel transfer tank.

Threaded 1" ports seem a bit oversized. Did not use or check the included 3/4" adapters. Used LOTS of Teflon tape, about 25 turns, to finally make watertight. Tried various 1" NPT male fittings and all were a little looser than normal. Otherwise product worked as intended and appears to be accurate.

This seemed like a well made device, but I didn't end up using it in my application.

Very hard to get PVC fittings to seal, even if Teflon tape and paste is applied

Bought this last year (2024) and it has been working fine so far....

Don't leave out in the damp. Make sure it comes in when not in use. Keep calibration and is on spot.
