Hi all,
Not 100% about Ignition, but my company are trying to manage our compressed air info such as usage , pressure, etc… ofc via Ignition.
In the past, we have tried couple of compressed air meter but problem is their min pressure threshold is quite high, therefore, it won’t detect any low pressure activity.
Is there any meters outthere that can cover something like 50KPA up to 1000KPA.
Thanks all
We’re starting to use some of these. But I think you’re run into the same issue at lower pressure. However, I believe they do have flow meters for low volume applications.
Keyence probably has what you need. We used their stuff all over machine air at my last job. Just go look at a sensor on their page and download a file if you don’t have a rep currently. They’ll ring your phone within 5 minutes.
One thing to watch: decide whether you want to monitor the normal, standard or "actual" air flow. (This is basically the uncompressed air flow or the compressed air flow.) The normal or standard might be more useful with reference to your compressors' capacity to figure out how close to maximum you are running. You can always convert if you have both the flow. The normal / standard meters work by mass-flow measurement. See https://www.youtube.com/watch?v=YfQSf2NBGqc&ab_channel=Endress%2BHauser for the principle of operation.
If you know the compressor power requirement for maximum output you might also be able to get a pretty good cost per unit volume which would be useful.
There's a good article here:
Another possible alternative is IFM’s SD series. We’ve used their pressure sensors extensively.
They also make I/O-Link masters that support a lot of protocols (MQTT, Modbus TCP, Profinet, E/IP, etc), so those can be connected to directly by Ignition.
