Afriso Mechanical Float Operated Tank Contents Gauge - for 2" NPT tank openings

Very simple gauge to install. Have to be a little careful, since it is made of plastic, so you don't crack it while tightening it. Would be nice if it had the ability to thread it into both a 1 1/2" and the 2" opening. This gauge is nice because it is a simple drop weight float, so there is no issue with the float getting interferred with by the older exsisting gauge system.

Upon receiving it, I installed it on my vertical 275 Gallon tank. I removed the 2" NPT cap and before I put on the new tank gauge, I measured the depth of the heating oil left in the tank, it was 26 1/4". According to the tank oil level chart: a depth of 26" indicates appoximately176 Gallons of oil (5/8 tank). After I installed it, it read 5/8 as seen in my attached photo - pretty damn good! The shipping was fast as well! The only thing that I feel less comfortable is, shipping is not free. When all put together plus tax, it's almost $50! And it's all made of plastic, so how durable it will be?

It is accurate

Does not tell the correct amount of oil in the tank. It was reading 1/4 left so I called for a fill and it only took 100 gallons. We have a 275 gallon tank. Easy to install

I really really like this gauge used for my 275 gallons heating oil tank. It's so easy to read like a vehicle fuel gauge. It's spot on for my oil tank height no string adjustment needed. This gauge can only be hand tight and it fits 2 inch opening hole on the tank. I just put a little silicone grease on the thread and the rubber o-ring and installed it.

I bought this in June of 2024 for my 275 gal oil tank. Installation easy and worked properly for my September fill but did not keep an accurate use as the small chain knotted and didn't allow the float to rise. Just saying I won't buy this one again

Love my new tank gauge. Easy to read, easy to install, accurate far as I can tell. Simple design, no crazy "float arm " .

I set the float as instructed but the way the float works is it is a fluid filled container so it requires a fair amount of product in the tank before it will begin to float so in my case it reads empty when I got 15 to 20 gallons of fuel left in the tank. So if you looking for accuracy this is not that great. As for my purpose I am happy with it so far.
