What is a Virtual Meter?
A virtual meter is a software meter that we create within E-Mon Energy™ to store calculated data from one or more
hardware meter(s). A virtual meter can have whole and/or partial readings from multiple hardware meters. In order
to create a virtual meter(s), we must first create a virtual recorder. Similar to a virtual meter, a virtual recorder is a
software recorder that we create within E-Mon Energy to have the same configurations as a hardware recorder. A
virtual recorder can have up to 8 virtual meters. Virtual recorders and meters only exist in E-Mon Energy database.
Within a group location, there can be up to 1664 virtual meters, i.e. 8 x 26 x 8 – 1A1, 1A2, …, 1Z1,…, 1Z8 up to
8A1, 8A2, …, 8Z1,…, 8Z8.
Virtual meters must be created in Location 0 of any Group number. This location can have multiple virtual recorders
and virtual meters. All of the virtual meter definition is done within the Virtual Meter tab on the Database window. A
virtual meter doesn’t have voltage, amperage, etc, settings comparing to the hardware meter; instead, it has a virtual
meter definition list box where you can add/define hardware meter(s).
Once the virtual hardware is added, a profile is generated for this virtual meter. These profiles are generated using the
current data from the database. The virtual meter profiles are done from the “Generate Virtual Meter Profile”
window.
Can I Change a Virtual Meter Definition?
Yes, once the virtual meter is created, you can add or delete a meter definition or modify an existing meter definition.
The following illustrates and describes the Virtual Meter tab on the Database Access window.
