HVAC & Building Automation

Integrated configuration for cooling/heating energy metering, hydronic differential pressure and AHU temperature monitoring.

Building automation is cost-sensitive while demanding ease of installation and communication compatibility.

Cooling and heating energy metering

Ultrasonic or electromagnetic meters combined with supply/return temperature sensors form heat meters for district energy metering and cost allocation. Ultrasonic offers lower pressure loss, suiting retrofit projects.

Hydronic monitoring

Pressure transmitters monitor supply/return differential for variable-speed pump optimisation; electromagnetic meters on critical branches support flow balancing.

AHUs and terminals

Sheathed RTDs or integrated transmitters on supply, return and coil temperatures; differential pressure transmitters across filters to indicate blockage and enable condition-based replacement.

System integration

All instruments should support RS485 Modbus RTU or BACnet gateways for integration into the building management platform. Mounting must avoid vibration sources and strong electromagnetic interference.
