3rd pressure gauge?

in the pneumatics manual it shows in the diagram 3 pressure gauges but the inventory list only shows 2 of them and we recieved 2. were going to use the setup on the diagram, but like i stated we only recieved 2 gauges. how can we do it with out it, or if we need them, can we use any gauges? i no i usually quote and stuff, but were extremely busy here :ahh:

You don’t need a third one. The Monnier regulator and gauge on the schematic is only if you want different pressures of working air for different parts of your pneumatic circuit. Chances are you won’t need it. Just forget it’s there if you are using the diagram for design.

Just make sure you have one gauge on the air storage side (which should go up to 115-125psi), and one on the working air side (up to 60psi).
