Can this digital flow meter be used on a gravity feed diesel line?

It should, as long as the pressure created on the discharge side is above 15 PSI. Please note this meter only goes down to 2 gallons. https://www.fillrite.com/index.cfm/products/productdetail/?p=615&ps=93

Can I use this meter to measure how much fuel and engine is using? Will it measure flow rates lower than 2 gpm?

Unfortunately, this will not measure flow rates lower than 2 GPM.

can it be used to see constant flow for glychol in a closed loop system to verify rate of flow

Yes, the meter can be put into RATE mode that displays flow rate. You may want to consider using the TT10PN, polymer version for Glycols as an option too.

Can this be used for detergent solutions?

You will want to use the TT10PN for detergent solutions.

Exact match, great price

This was ordered as a replacement for one used on a field service oil dispensing system for genset engines. Our local supplier of this equipment had on of these on hand... but his markup was 200+% of what I paid for this one from Amazon!
