Metering systems are a valuable tool for the automatic monitoring and measurement of your energy usage and can help identify areas of incorrect over or under billing by your supplier. During an installations lifetime, the users of your existing sub-metering system may move on and the site usage and infrastructure can change.  As a result a sub-metering system can become confusing and the original installed system can become lost in a maze of changes.

A typical sub-metering system can have a variety of metering points for electrical, gas and water usage which are relied on to produce data for billing and for monitoring energy consumption. The reliance on these old sub-meters and systems can sometimes lead to the information it provides not being trusted and deemed unreliable. If this happens systems are in danger of falling into disuse and being forgotten.

Before considering an upgrade and additional investment in a new Energy Management System, your existing sub-metering system can be re-evaluated with a simple on site audit. The sub-meters are identified with their function, their output and for electricity meters a measurement of their accuracy is recorded.  This can mean that your metering doesn’t need to be replaced and the data they collect can be reliably used. For metering identified as giving an incorrect reading we will recommend solutions and where needed, replacement electrical sub-metering can be proposed which can be simply integrated into your existing system.

The sub-metering audit report will record and provide you with information specific to your energy management system.

During the site audit we assess each metering point for –

  • Meter Manufacturer.
  • Meter Model.
  • Measurement type
    • Electrical Metering
      • Current Transformer Settings.
    • Gas Metering
      • Δ Min/Max Gas flow.
    • Water Metering
      • Q3 Flow.
  • Available outputs
    • Output Y/N
      • Type of output, Pulse or RS485.
    • Meter location.
    • Network point ID where applicable.
    • What the meter is connected to.
  • Site Location.
  • Comments on any connected equipment.

Please contact us for more information and we will be happy to arrange a quotation or initial site visit to assess your requirements further.
