Diesel Flow Meter

[chrisinkanata]

I'm looking for a diesel fuel flow meter that I can install between my 60 gal. aux. tank and the main tank. In searching, it seems that this is not as easy as you'd think. There are some digital devices available that are relatively expensive and do not appear to be very weather proof. They are also fairly large. Ideally, I'd like to get an in line sensor with a read out in the truck but that's a dream it would appear. So, a simple mechanical device that simply counts the gallons flowing through it.

Anyone seen anything like this....?

Thanks,

Chris
