energy sub-metering
The CEM series meters are intended for DIN-rail installation and are designed to read
electrical energy, reporting consumption in order to manage industrial or commercial
installations, production lines and service rentals.
In order to monetize the energy consumed by each user, invoicing meters have to be
installed that can report the exact amount of energy consumed, either by checking the
consumption information shown on the display or via RS-485 communications that can
send the information to management and billing software using the Modbus protocol.
Invoicing meters have to comply with IEC 62053-21 (Class 1 for active energy)
internationally or, in Europe, with the MID certification by means of the EN 50470
(Class B for active energy) standard. The MID certification includes the IEC 62052-11,
IEC 62053-21 and IEC 62053-23 standards, making it the most suitable option for any
type of installation.
The MID certification is essential for those meters used
to invoice energy use, as they ensure the reliability of the
consumption logs used to bill the end user.
