Hi,
I need a method to measure flow rate of a suction/blast peening setup. The high tech valves on the market that control and measure flow rate would require too much machine modification and cost. I have seen a few mentions of a catch bucket method, primarily from The Shot Peener (Volume 3 Issue 3 Fall 1989). Almost everything I found online mentions general testing procedures, but does not go into detail on the catch bucket itself.
--Does anyone have experience with the catch bucket method?
--Are there any good design guidelines or suggestions to an effective catch bucket (material, geometries, relieving built up air pressure, etc.)?
A second question:
--Will there be any effect on my flow rate measurement if I isolate only one nozzle to run at a time for the test, versus running all nozzles (8) and catching only one nozzle at a time worth of shot?
I ask because when the machine runs with only 1 nozzle, the pressure gauge reads a few psi higher.
Thanks
