System Integration & Application Flexibility
Designed for versatility, the SFM472 series meter caters to dual operational modes to meet diverse on-site requirements:
1. Local Display Function: The meter features an on-board display that provides real-time visualization of measured parameters, enabling field personnel to conduct quick spot checks and verify system performance without additional equipment.
2. Centralized Measurement & Control System Integration: Beyond local monitoring, the meter’s detection data can be seamlessly transmitted to industrial control equipment (such as PLCs, RTUs, and SCADA systems) and host computers via standard communication protocols. This integration enables the construction of a unified, centralized measurement and control network, supporting remote data acquisition, real-time load analysis, energy consumption auditing, and automated power system management.
With its robust measurement precision, compact DIN-rail form factor, and flexible integration capabilities, the SFM472 series meter is ideally suited for real-time power monitoring in 3P4W systems across manufacturing facilities, commercial buildings, data centers, and utility substations.
