External Measuring Components

External measuring components are used to model measuring components for data that is not stored or used in the system. For example, some meters may have channels (measuring components) that capture data not used my Meter Data Management or Customer to Meter, but that should be passed on to other external systems such as Oracle Energy and Water Data Intelligence.

For example, if your implementation has interval meters that record 2 channels of data (kWh and Amps), but only the kWh channel is used for usage calculations, you would set up the kWh channel as a Physical interval channel and the Amps channel as an External channel. Data for the kWh channel would be processed as usual, but the data for the Amps could either be filtered entirely, or passed through to an external system.

Incoming data for external measuring components of this type can be filtered or passed through to other systems, preventing errors generated by incoming data for measuring components that don't exist. See Filtering Data for External Measuring Components below for more information.

External measuring components are defined by the following;

  • Device Configuration
  • Channel ID
  • External ID
  • MDM External ID
  • Number of Digits Left (Used for consumption calculations when passing data through to an external system)
  • Number of Digits Right (Used for consumption calculations when passing data through to an external system)
  • Channel Multiplier (Used for consumption calculations when passing data through to an external system)

The base product supports the following external measuring components:

  • Interval Channel - External (D1-IntervalChannelExternal)
  • Scalar Channel - External (D1-ScalarChannelExternal)

Like "regular" measuring components, external measuring components are related to a device through a device configuration, and can be considered "active" for purposes of install events, but are not used in usage calculations for usage subscriptions.

Like "regular" measuring components, external measuring components and viewed and maintained using the Measuring Component portal.

Filtering Data for External Measuring Components

Incoming data for external measuring components can be filtered (deleted) or passed through to an external system via object storage. Note that payload statistics track the number of initial measurements filtered and passed through.

Filtering data for external measuring components is supported with Direct Measurement Processing ONLY. See Direct Measurement Processing and Measuring Component Ordering for more information.
