Our most popular smart metering solution is our Guru Hub with pay-as-you-go and controlled credit services

How it works Documentation

Credit billing systems
Site M&E considerations and requirements

Any credit billing system relies on regular and accurate heat meter readings from all the properties connected to the heat network. Readings must be remotely collected from the properties, and transmitted or collected from the site by Insite using web based technology. A system like this is generally referred to as a remote Automated Meter Reading (AMR) system.

A remote AMR would typically comprise of the following components:

  1. Heat Meter (mains or battery powered) within the property with a wired MBUS output.
  2. A site-wide cabled network, called an MBUS network, which connects all the heat meters back to a single location such as the plant room. NB: There are various cable types used for MBUS networks, Insite recommends the Belden 8444 multi-core cable.
  3. A site datalogger at the point the MBUS network converges to record the readings from the heat meters on a daily or more regular basis. There are many makes and models of datalogger available on the market. Insite recommends the open protocol IZAR Centre M range for this purpose.
  4. A high grade router and connectivity to a fixed IP (static) broadband connection. This provides the remote connectivity to site in order to collect or transmit heat meter reading data used in the billing process.

NB: Where wired MBUS data networks do not exist (retro-fit) or cannot be accommodated within the design of a site, radio based alternatives provide another option for MBUS data collection from within the properties. Typically these are alternative solutions and are only used in the event a wired solution is not feasible.

PAYG systems
Site M&E considerations and requirements

Example based on Guru Flexi-Pay solution

The following list of site M&E considerations is based on a typical installation of a Guru system with an optional hard-wired MBUS network running in parallel. It covers the main considerations that any installing M&E contractor would need to have allowed for within their scope of works in order to successfully install a Guru system.

This list is a guide only, and whether a new build or retro-fit project, there are typically options and solutions that may deviate somewhat from this prescribed list. Adaptability and flexibility where possible are key to success.

  1. Provision of a 5A un-switched fused spur in each property for dedicated supply to the Guru Hub
  2. Installation of Guru Base unit in HIU cupboard of each property.
  3. Inclusion of Mains Powered Heat Meter with Dual Wired MBUS outputs – Meter make / model to be on Guru Systems Ltd ‘approved’ list.
  4. Inclusion & installation of Prepayment control valve for use by Guru system. Recommended is Cimbario 602RE available from SAV Systems and available factory fitted within HIU. NB: Other HIUs such as Altecnic & Elco solutions also have factory fit compatible value options.
  5. Installation and testing of site wide wired MBUS network utilising Belden 8444 cable throughout site, converging on single data collection point (subject to site survey and distance limitations of MBUS).
  6. Connection within properties of Heat Meter MBUS output, Mains Power & Valve fly lead to Guru Base Unit in accordance with Guru installation guide.
  7. Provision of AC240v switched sockets within electrical risers for dedicated use by Guru Radio Repeaters (locations to be specified in RF survey).
  8. Ordering and installation of ADSL Fixed IP broadband for use by Guru system in location(s) identified by Insite RF Survey. Provision of 4x switched sockets to same location(s).
  9. Installation of secure cabinets in risers and plant room to house Guru infrastructure equipment in locations identified in RF survey.
