A Google search for RCM-7000 only found a "coverslipping machine" whatever that is? So what sort of flow gauge is it that you've got there? 
 
I found the same thing, but looked at the "completed listings" on ebay this morning.  I found this:  http://tinyurl.com/6memj   Looks pretty nice to me.
 
Same Question? Whacha got? Can either of these be used in flight or is it just for ground tests? Are these an orifice type? (square root extraction of DP). If so then they will add a little restriction, but this is where that pressure recovery and permanent pressure loss comes into play. 
 
Overnight, I kept thinking of limitations to the meters that I ordered last night, so this morning I bit the bullet, and ordered a better one instead.   The one I just ordered is 4-50 gpm,  and will be ground only. 
 
Cheers,
Rusty (need to work some OT to help pay for this)
 
Vane-Indicating Flowmeters
Click to change image size    Maximum Pressure: 200 psi @ 400° F
 Maximum Temperature: 400° F
 Accuracy: ±2%
     A 17-7 PH series stainless steel vane indicator moves in proportion to flow rate and is unaffected by mounting position, so it can be used in both horizontal and vertical applications. There are no mechanical linkages, no floats that could stick, and no tubes to clean—ideal for use with liquids containing solid particles that clog conventional meters. All have a direct-reading scale. The housing is brass with a tempered-glass window; flowmeters also have EPDM O-rings. Connections are NPT female, unless noted.
     To Order:  Please specify direction of flow: left to right, right to left, up, or down.
