Simple Mechanical Blowcase Cycle Counting
Simple Mechanical Blowcase Cycle Counting
(OP)
Hi,
Do you have any suggestions for a simple method of counting blowcase cycles on a small booster compressor package.
I was thinking of using a pneumatic cycle counter on the instrument gas line that acutates the valves. The problem is that I can't find anything that can be used with natural gas.
We don't have any power on site so no fancy transducer devices.
Thanks,

The simple turnstile counters are a bit too simple and tend to be very fragile.
I've had better luck with an Ashcroft pressure switch (I got it from PreMac http://www.premacinc.com/index.php but any Ashcroft dealer should be able to help).
Counting pulses on a Barton chart could work, but you would have to calculate your volume manually.
