Industrial Energy Management and Electrical Power Measurement Systems

Finder has developed MID-certified measurement devices to ensure the management and optimization of electrical consumption in modern infrastructures. These hardware solutions integrate bidirectional communication protocols to transmit operational data to centralized control systems.

Technological Evolution and Legal Certification
The transition from electromechanical devices to smart digital meters allows the continuous processing and recording of voltage and current data via transducers. To guarantee the legal validity of measurements intended for billing or the accounting of photovoltaic energy, the equipment must comply with the European directive MID 2014/32/EU. This technical compliance is validated by specific tests and identified directly on the device by the CE marking, the letter M, and the year of certification.

Network Architecture and Communication Protocols
The hardware configuration of the electrical network determines the selection of single-phase, two-phase, or three-phase models depending on the applied loads. With the deployment of self-production installations, measurement distinguishes the energy drawn from the grid via unidirectional meters and the import and export flows via bidirectional meters. Telemetry data is transmitted to the OPTA Energy Monitor centralized management system by Finder using Modbus RS485 or M-Bus industrial communication protocols, or S0 pulse output interfaces.

Technical Specifications of the 7E and 7M Series
To meet hardware integration requirements, Finder offers the 7E Series designed for electrical panels requiring direct, certified reading without complex field programming. This range includes the Type 7E.85 model, a multifunction bidirectional meter for three-phase systems (3 or 4 wires) simultaneously integrating M-Bus, Modbus RS485 interfaces, and a dual S0 output. Concurrently, the 7M Series brings remote configuration capabilities through integrated NFC technology, allowing operators to set functions and consult Type 7M.24 (up to 40A) and Type 7M.38 (up to 80A) meters via the Finder Toolbox mobile application. These devices provide precise measurements of consumed and produced energy, operating stably even at high temperatures to support electric vehicle charging stations and photovoltaic flow management.
