GMC Metering regulator

[p1p]

I have the nuvair pro trimix analyzer, and am hooking it into my compressor output for trimix blending.

The Nuvair states it works with .5-2L gas flow.

I was looking at this regulator Automatic Metering Regulator to use to meter the gas flow into the analyzer but was concerned if its too much gas flow(states 2-4L, is it adjustable?).

thx!

or alternatively, nuvair has a flow restrictor that is adjustable from .5-8l, with gauges for the same price.

I find the best way to tap into your compressor output is with a Street Tee, isolation valve, and yoke block. Then you can hang an old scuba regulator at the output of your compressor, and use an adapter that plugs into the BC hose. Check out these links.

^That is what I do, but I have a reg tester/regulator mounted into the plumping system for the banks. My friend gave me an old reg with a second stage that I put an LP inflator hose on and it allows me to check O2 output and monitor for CO, with my Nuvair meter (Plugs into compressor to kill it in a CO event), with both using the same the low pressure connecter at the same time with a plastic Y fitting (I am not blending trimix, just nitrox). My equipment is portable and lives in a sealed box so it can travel when needed.

This is the equivelant of what I use for a n inflator hose connector. Great for in the field gas testing. Should be available from your favorite dive store.

I bought this Dwyer flow meter for $10 from Ebay to run my CO off of, but haven't set it up yet. It requires a regulator before it first also. Cat. Number VFA 2 BV
