Intelligent Energy Monitoring with M-Bus and NFC Technology
The Finder 7M.24.8.230.0310 provides comprehensive electrical energy monitoring for single-phase installations. In addition to recording imported and exported active energy, the meter can display reactive energy and instantaneous electrical parameters including voltage, current, power factor, active power, apparent power, reactive power, frequency and total harmonic distortion. These measurements help electrical engineers and energy managers understand consumption patterns, identify abnormal operating conditions and evaluate electrical system performance.
The integrated M-Bus interface enables energy measurement data to be collected through compatible wired metering networks. This makes the meter particularly useful for building management systems, centralised energy monitoring, commercial sub-metering and installations with multiple electricity meters. Its NFC functionality allows compatible smartphones running the Finder Toolbox App to configure the meter and access stored energy readings, including when mains voltage is unavailable.
The combination of MID-certified measurement, bidirectional monitoring, a backlit LCD display and compact DIN rail construction makes the Finder 7M.24.8.230.0310 a versatile solution for modern electrical installations.
