Managing Meter Replacement

You have to manage the meter configuration and values each time a meter is replaced.

​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 .

To manage meter replacement

  1. In WorkStation, in the System Tree pane, select the trend log whose meter configuration you want to manage.

  2. On the File menu, click Properties .

  3. In the End time box, enter the end time of the old meter.

  4. In the End value box, type the value of the old meter when it was replaced.

  5. In the Start time box, enter the start time of the new meter.

  6. In the Start value box, type the current value of the new meter.

  7. In the Meter constant box, type the constant value of the new meter.

    Important:

    • Type the constant of the new meter if unit conversion is not used in the trend log, for example, the old trend log counted in grams and the new one counts in kilos (10 3 ) type 1000.

    • If unit conversion is used in the trend log - do not change the meter constant.

  8. In the Min value box, type the first value of the new meter when it rolls over.

  9. In the Max value box, type the last value of the new meter before it rolls over.

  10. Click OK .
