3.2 Meters and media
3.2.1 Meters
EMC operates with four different types of meter:
• Main meters
The main meters register energy consumption in a central location (e.g. the dis-
trict heating transfer meter belonging to the utilities company)
• Sub-meters
These measure a part of the energy flow recorded by the main meter (e.g. the
heat meter for one floor of a building)
• Invoice meters
It is possible to enter the consumption as reported in the utilities company bill.
• Other meters
Other meters register other consumption and media data (e.g. outdoor tempera-
ture)
The application allows you to set up the contractually agreed number of meters.
All meters can be configured freely in EMC in relation to the medium, units, period
of validity etc.
Multi-rate meters are electricity meters with separate registers for power and con-
sumption, or for different tariffs.
