A measure of consumption

A field trial by the Carbon Trust showed that, on average, organisations that switch to using advanced metering reduced their carbon emissions by 12% and achieved financial savings of five% through reduced utility consumption. Sub-metering is also covered under Part L of the Building Regulations, which requires at least 90% of each incoming energy source to be accounted for through sub-metering and additionally in larger buildings (over 1000m2) to include automatic meter reading and data collection facilities.

Trend has introduced a range of four easy to install and simple to use electricity sub-meters that can be integrated into the Trend BEMS. These multi-phase devices can be supplied with the option of either open-collector pulse outputs or Modbus communications. They are also available for either direct connection to the measured supply or connection using 5A current transformers.
