Fill-Rite 820 1" 2-20 GPM(8-76 LPM) Digital Nutating Disc Fuel Transfer Meter for Use with Water, Diesel, and Mild Chemicals

I’ve had this a month or so it seems to be working fine. Very easy to calibrate with the preset calibrations.

Put these on all my farm's transfer pumps. Small, easy to read, easy to use. Only had them 4 mon so I don't know how well they hold up, but they seem pretty tough and well made

Had this for a bit more than two years. Pumped less than 400 gallons of diesel through it. It was outside on a tank but out of the weather - not getting beat up in the back of a pick-up or anything. Never directly exposed to water or vibration. Diesel that went through it was filtered. Failed shortly after warranty expired (2 years). To their credit, Fill-Rite at least had customer/tech support and they were helpful but I was out of warranty. Since I had to buy a new one again I got a cheap Chinese unit. So far that works just as well. I like to buy American but not when it costs five times as much and still craps out.

I installed this on my farm diesel tank that sits outside in the sun/weather. It was easy to install/setup and worked great for about 4 months. Then the rubber cover came off and soon thereafter the unit would no longer count gallons (but fuel would flow through it). When I got done harvesting, I called the customer service department. I told them my meter broke and I wanted a more reliable mechanical unit (which evidently costs more). They sent me the mechanical replacement which mounts directly to my specific pump -- at no cost.The technical support rep (Jeff) was very knowledgeable, very responsive and easy to talk to. It was a welcome change to other customer service interactions I've had elsewhere. Alhough the product did not last long for me (I would have given it 1 star), the customer service more than made up for it.Even though the meter appears to be well sealed, you may want to be careful using it where it will be outside all the time. Also, I used a pipe sealant for installation. Although I'm relatively confident I didn't put too much on, I would recommend using Teflon tape to prevent sealant from migrating into the meter.

For those of you leaving one-star reviews on this product, do a bit of research and maybe call Fill-Rite customer service. Their tech support is the BEST! Very knowledgeable, friendly, and eager to help. I had mine for about a year then for some reason the display was coming on but the meter display was staying at all zeros. Not good. So, I called tech support and they asked me to read the serial number on the bottom to them, which determines the date of manufacture and sale. If it's under TWO YEARS they replace it! How 'bout THEM apples!

This was the perfect solution for a 400 gallon fuel trailer with 40' hose reel. No more walking back and forth to the trailer to check a pump mounted meter. And I really like that it has selectable calibration options for different liquids.

I hated to spend the money considering the less expensive ones on amazon but it is well worth the piece of mind it works and hopefully lasts.

I love this meter. It works exactly as described in the description. I have not experience any hiccups with this unit. So far, it has worked exactly like its suppose to. Currently, satisfied!
