Fe guage

[Dolly Sprint 16v]

Is there a way to see how much co2 is left in my fe using a duel gauge reg!?
Cheers

yes - if you have a dual gauge the dial on the left hand side of the reg usually bottle pressure and the guage on the right is line pressure after passing through the reg the pressure drops dramically from 50 bar (new bottle) to between 1.0 - 2.5 bar which depends on how many bps you are running with.

So when the FE is new it will be 50 Bar - then decrease over time to 1 bar?

The gauge should read 50 bar on a full FE and as time goes by the FE will empty and the needle on the gauge will drop. If your gauge has increments you will be able to see what pressure is left in the bottle but if its the old style JBL gauge there is a red portion that the needle enters when the pressure is low - see attached picyies.

JBL gauges / reg.

Bottle pressure reducing - needle has moved off 50 bar and is showing about 39 bar.

Thermo gauges / JBL reg body.
