Meter Relationships

Introduction

Meter Relationships gives you:

  • The ability to manage and visualise the complex hierarchical structures of metering - providing the ability to add Parent/Child Meter relationships to Meters, Sub Meters and Virtual Meters
    • Use this to perform gap analysis and identify potential metering problems on your sites.

This sections shows you how to create the Parent/Child hierarchy, with the introduction of the Meter Relationships popup. This popup shows the relationship between the Parent and Children in relation to Meters, Virtual Meters and Sub Meters.  It also shows any errors or warnings regarding analysis of the data in the Channels.

The Tree expands to show all of the Meters / Sub Meters / Virtual Meters for the Site and you can see the Parent / Child relationship.  There is also the capability to allow you change the relationships from this popup.

The Asset Type is also displayed in the popup.  Click for more information on Asset Types

Use the Gap analysis at the bottom of the popup enables you to see if the data in the Child Meters add up to the data in the Main Meter.  For example, you may have a Main Meter that has 4 Sub Meters, and one of those Sub Meters, also has two Virtual Meters related to it.  See below:

         


The popup is accessible from the Data Selector by selecting the Site or Meter or from the Data Management Activity.

Understanding the results

The remaining columns will populate data in the Value, Unit, Notification Count and Errors/Warnings fields

  • Value - the Units in the Channel for the period chosen
  • Unit - the Unit type, ie kWh
  • Notification Count - The amount of outstanding Notifications in the Data Monitoring Activity (only applicable to Meters with Periodic Channels)

          Note:  Click on  to open the Data Monitoring Activity, filtered to the Site

  • Error/Warnings - Shows any Errors or Warnings for the Meter, ie 'The Value for this meter is not equal to the sum of its child meters'

         


In the above example there are two calculations as there are two Parent Meters - Meter 12345 and Communal Area


Calculation Examples

Meter 12345

If the criteria had a tolerance of 0%:

  • Meter 12345 = 1000 kWh
  • 450 kWh  (Flat 1) + 300 kWh (Flat 2) + 100 kWh  (Heating ) + 100 kWh  (Communal Area ) = 950 kWh
  •  There is a different of 50 kWh, the message shows that the Value for Meter 12345  is not equal to the sum of its Child Meters

         


Communal Area Sub Meter

If the criteria had a tolerance of 20%:

  • Communal area Meter = 100 kWh
  • 25kWh (External Lighting) + 50 kWh (Internal Lighting)  = 75 kWh
  • There is a difference of 25 kWh, the message shows that the Value for this Meter is not equal to the sum of its child meters.  75 kWh (total of  Internal and External Lighting)  is less than 20% of 100 kWh (Communal area)
