Trend Control Systems has developed a range of four ‘easy-to-install, and simple-to-use’ sub-meters designed to work with its building energy management systems (BEMS).
“A Carbon Trust field trial showed that, on average, organisations that switched to using advanced metering reduced their carbon emissions by 12 per cent, and achieved financial savings of five per cent via reduced utility consumption,” Trend explained. “Sub-metering is also covered under Part L of the Building Regulations, which requires at least 90 per cent of each incoming energy source to be accounted for through submetering, and, additionally in larger buildings (over 1,000 m2), automatic meter reading and data collection facilities.”
The multi-phase sub-meters can be integrated into the Trend BEMS, and supplied with the option of either opencollector pulse outputs, or Modbus communications. They are also available for direct connection to the measured supply, or connection using 5A current transformers.
