Revision history [back]

I've used Meter:Custom for energy in the past, but never used it for a typical Output:Variable. I'm trying to aggregate all of the outdoor airflows of a bunch of PTACs.

When I do so, this warning below results - and none of the airflows are added to the meter. Can one of you add some light here? Thanks in advance.

The object looks like:

Meter:Custom, OAflow, !- Name Generic, !- Fuel Type Floor1:NWTHCorner PTAC Outdoor Air Node Name, !- Key Name 1 System Node Standard Density Volume Flow Rate, !- Output Variable or Meter Name 1 .... etc for several nodes....

Here's the warning (repeated for all 20+ nodes)

* Warning * DetermineMeterIPUnits: Meter units not recognized for IP Units conversion=[m3/s]. * ~~~ * ..on Meter:Custom="OAFLOW". * ~~~ * ..requests for IP units from this meter will be ignored. * Warning * Meter:Custom="OAFLOW", variable not summed variable Output Variable or Meter Name="SYSTEM NODE STANDARD DENSITY VOLUME FLOW RATE". * ~~~ * ...will not be shown with the Meter results; units for meter=m3/s, units for this variable=m3/s.
