What type of energy meter is used for building automation?
DIN-rail single-phase or three-phase energy meters are commonly used in building automation systems. RS485/Modbus models are suitable for integration with BMS, BEMS, gateways and energy management platforms.
Can YTL meters connect to a BMS system?
Selected YTL energy meters support RS485 communication and Modbus RTU, which can be used for connection with compatible BMS controllers, gateways or data acquisition devices. The protocol and register map should be confirmed by model.
Which meter should I choose for HVAC or lighting monitoring?
For small single-phase circuits, a single-phase direct-connected DIN-rail meter may be suitable. For three-phase HVAC, pumps or distribution panels, a three-phase direct-connected or CT-operated meter may be required depending on current range.
Is MID certification required for building automation meters?
MID certification is generally considered when metering data is used for billing, tenant cost allocation or regulated energy measurement. For internal monitoring only, certification requirements depend on the project and local rules.
Can one building automation project use different meter models?
Yes. A project may use single-phase meters, three-phase direct-connected meters and CT-operated meters at different measurement points, depending on load type, current range and installation space.
What information is needed for meter selection?
Phase type, voltage, current range, direct or CT connection, communication protocol, accuracy class, certification requirement, installation width and BMS integration method should be confirmed before selection.
