The Factor 4 team has installed an ultrasonic clamp-on heat meter to monitor in real time the energy delivered to building NE1 in the form of hot water produced at BCIT’s central plant.
The team decided to purchase and install a Siemens Sitrans F meter consisting of a clamp-on ultrasonic flow meter, 2 temperature sensors (RTD: Resistance Temperature Detector; one on the supply line and one on the return line) and a central transmitter.

The pulse signal is sent from the Siemens meter through a standard 18 Gauge Shielded cable to the next room (NE1 electrical vault) where our Schneider Ion 7350 electrical meter was available to receive one more input. The Schneider meter receives kWh data from the Siemens meter (with Delta T and flow, GJ or kWh can be calculated). The data is then sent to BCIT’s Schneider Enterprise database where it can be retrieved by the GAIT EMS system and read by the Factor 4 team.
The Factor 4 team partnered with BCIT GAIT team and BCIT Facilities and Campus Development to select, install and integrate the meters.
