Flow Meter 1 Inches, Turbine Fuel Flow Meter 2.5-31 GPM, Digital Flowmeter Aluminum Alloy Engineered Fuel Meter ±1% Accuracy for Measure Diesel Kerosene Gasoline, Supports Gallon, QTS, PTS, L, m³

I absolutely love this flowmeter. I use it for applying pesticides and herbicides. I put hydraulic qyick connects on both ends. I callibrated my equipment and this thing is perfectly accurate. the best part is the price. Super affordable. I had a different brand and it was much more expensive and it blew apart on the 1st use. I had and continue to have no issues with this one.

Excellent product great price point. Full metal housing is very duarable. The diameter if the threaded inlet and outlet were spot on and installation was a breeze. Would reccomend to anyine needing a accurate long tern solution for a flow meter. Unit did need calibration but this was a simple process as well

I've had it for 2 months now but just got around to installing it a week ago. At first it worked but leaked fuel. Last night it raines and now there is moisture under the screen and it won't work at all. I can't return it because it's been past the 30 day return period.

The body of these meters is solid and easily usable to support something heavy, if needed. It also seems like all of this type of Amazon water meters are essentially the same design, so it’s unclear if there is a higher quality variant. This one came with 3/4” fittings without any adapters.I cannot speak for the accuracy out of the box, but the adjustment (calibration feature) should be able to account for over or under reporting and is pretty self explanatory if you understand basic math.What’s not at all obvious and is just wonderfully, horribly translated into English — the instructions! While most of it is just pushing or holding down a button, the mode worth mentioning is the ability to reset the total count.To reset total count, once you remove the batteries, you have to hold down display button as you insert the batteries again. This took a bit to figure out even after contacting and receiving a more complete guide from their support. (At least they tried!)As far as waterproofing, I can see how the tiny gasket between the enclosure and the electronics could eventually leak. So, it would be advisable to keep it away from excessive water flow and rain.If you pay attention to the above, you should have no problems: -1 star for bad instructions.

I live on a ranch out on acreage. I'm constantly dealing with fuel, oil, and water and moving it around the property. Not everything is perfect as a container and a lot of times I don't even know what the capacity is of certain things. This is such a simple device and easy to use with the instructions. I'm able to tell how much water I'm consuming on my irrigation systems and I can see how much fuel I'm putting in my old tractors as they don't really have gauges. The thing feels solid and well built. It's a nice cast aluminum with very well machined threads on the input and output. It arrived calibrated already. I'm probably going to buy several more and put them on different connections around the property.

Works great

This item was a piece of junk. Always cause problems. Finally just quit working right after the return dateI must say their customer service has been outstanding. They sent me another meter on their dime with English instructions. I can understand. I will have it installed tomorrow and will let you know. Very happy with the service now

I didn't get a free one, I paid for mine so this is a real review. Just like in another review, I could not get this one to stop leaking. The readout was stuck on liters. Nearly impossible to change to gallons. When I finally got it to say gallons I filled a 55 gallon drum, it was over 246 on the meter. I thought it was a fluke so I got a replacement. Same problems with the second one. We have several fuel meters at this location and we have been using similar meters for probably 8 years with no problems. I have had NO luck with these. Going to another supplier. Good Luck if you get one of theses.
