Meter Function

​The meter function adds meter properties to any trend log type to seamlessly handle consumption calculations independent of meter rollover or meter exchange.

You create and configure the meter function in trend logs using WorkStation.

For example, in the figure below, the meter function in the trend log records a meter the 1st of every month. In the middle of February, the meter rolls over to 00000. A chart with meter consumption calculation prints the consumption every month.

The calculation function supports negative meter consumption values, which can be used to handle cases where you need to subtract consumption, for example, when energy is produced on site.

When physically replacing an old meter with a new one, you have to configure the meter function of the trend log by adding the configuration and values of both the old and the new meter. These configurations and values are the foundation when handling a meter rollover or calculating consumption though meter replacement. For more information, see Managing Meter Replacement .

Note:
  • In order for a meter rollover to be managed correctly in the meter trend log and to ensure logging starts at the correct energy reading value, you enter previous meter and new meter information in the Manage replacement of meter dialog box. For more information, see Managing Meter Replacement .
