how do i calculate actual mass flow through a compressor without flowmeters?

[NH3LVR]

My curiosity has the best of me.
I learned on 2 Cylinder VSA Ammonia Compressors.
The biggest I have personally worked on was a 14 X 10 inch X 4 Cyl Kohlenberger.
I have never heard of Clark.
The part about 4 cylinders, every other revolution I am not too clear on.
Perhaps you could give us a little history on the machines and their Manufacture, as well as explain the every other revolution part.

Was hoping someone would reply to this. I really am interested.

Had no idea reciprocating machines were built this big.
Very interesting stuff applied to an NH3 system.
Appreciate it Ranger.
