Natural Gas & Steam meters

Hi all,

My customer is planning to start monitoring natural gas and steam usage by machine in the upcoming months and I was wondering are there any units that are proved to work well with Ignition?

All the controls systems are Allen Bradley. Ideally it will be great to get meters that can plug straight to the PLCs but MODBUS or TCP/IP units will the job too.

Will be grateful if anyone share their experience with gas and steam meters that worked well for them. Thanks!
