Hi Karthik:

In order to find out how much your compressed air is costing you, first you need to audit each compressed air using piece of equipment, then convert that compressed air consumption into dollars.

This is time consuming, for sure.

If your machinery is using air cylinders, then you can get air consumption info here.

If your equipment is using other than air cylinders, you'll need to contact the suppliers of that equipment to find out the air consumption.

As to converting compressed air into dollar cost, here is information on that.

Doing a complete air audit is complex and time consuming. If you do one though, you will be amazed at just how much compressed air costs, and this will motivate you to take steps to conserve this expensive energy source.

Cheers,

Bill

Another way
by: CR

Likewise, You can install something like this

http://www.powermeterstore.com/p6539/em6433_power_meter.php

on the electrical power line to your compressor, turn off the air to all but one user, run the compressor till it shuts off, then monitor the usage in kWh. Then monitor the system under normal use to calculate the total cost per unit of time. Use these two numbers to calculate a percentage use for the device in question and multiply this percentage to the total maintenance cost of the system and add the result to the kWh cost per unit of time for the user.

(Note, I have no affiliation with this meter vendor.)

Or...you can use a compressed air flow meter
by: Pascal van Putten

Now, I dont want to make this too much a commercial statement, but this is typically a task for a compressed air flow meters.

With the VPFlowMate-lite, and the VPFlowScope, you can pre-program your costs per CF/ m3 and get a real time view on the projected annual costs. Just like with your electricity meter at home.

Of course, there is a difference between the cost you see at the consumption point and the cost of generation, but it gives quite a good indication.

Pascal, interesting product. Please email me a press release on them so that I can feature them on my blog.

Thanks,

Bill
