Model U181, U187, U189 - Energy Meters for 4 Quadrants, 2 Tariffs, Calibrated
From Power System Monitoring - Energy Management - Energy Meters
The calibrated, compact energy meters included in our Compact Line product range can be used to acquire and bill active energy in industrial, household, commercial and building management applications. Relevant values are transmitted to data logging, billing and optimizing systems, as well as to building automation and control technology applications, by means of 2 pulse outputs or the integrated infrared interface and an external interface module. Modbus, M-Bus and Ethernet are currently supported.
