Bonvoisin Turbine Flow Meter 1" FNPT Inlet/Outlet Fuel Flowmeter ±1% Accuracy LCD Display Flow Meter for Diesel Kerosene Gasoline 2-26.4 GPM /9-100 LPM(Batteries are not Included)

Using this to monitor raw water flow on a marine diesel engine. Works great.

Like the price, this is similar to an inexpensive consumable I currently use, however it does not contain a gasket between the body and the pickup head electronics, this is absolutely not weather resistant.

It take’s batteries big NEGATIVE if you’re pumping 4000 gallons or more a week your batteries die quickly the lens constantly fogs up and you can’t see the numbers then you have to take it apart clean the lens wipe it off and maybe the last another day or two my advice do not waste your money

didn't last more then 30 days second set boughtunfortunate lost money integrals just fell apart

Leaks out of the box absolutely garbage not worth a dollar its crap

Save yourself the money and hassle, doesn't work and hasn't worked since day one. I ended up replacing with a name brand product that works.

Nunca dio la medida y es demasiado variable

No sirve lo puse y al otro día ya no trabajaba
