Administrators of shopping centres, airports, hotels, offi ce complexes and other commercial properties all face the same challenge. How can energy effi ciency be increased whilst at the same time assigning the costs to all of the tenants in a fair and precise manner? Both objectives can be achieved with the MID energy meters.
The assignment of the energy consumption to the individual tenants or consumption points can be made signifi cantly easier through comprehensive acquisition. Sources of energy wastage are quickly identifi ed, undesired energy consumption can be reduced and the energy effi ciency increased.
Electronic energy meters are primarily used for the recording of effective energy and reactive energy. Their area of application is in the fi eld of energy management for cost centre analysis. Various communication options are available for this in order to avoid the time consuming process of manually reading out on-site. As a measured value transducer the effective pulses on a control system, e.g. GLT, SPS, SCADA or the ProData® data logger incl. GridVis® network visualisation software, can be switched via pulse outputs.
The M-Bus and Modbus RTU protocols are available via the integrated communications interface for the fi eld of building control technology. With the corresponding selections these interfaces enable the additional values of voltage, current, power, power factor and frequency on the bus, alongside effective power and reactive power. The energy meters can be used for consumption data acquisition, in conjunction with the measurement devices UMG 96RM-E, UMG 604, UMG 605, UMG 508, UMG 509, UMG 511 and UMG 512 via Modbus RTU for sub-measurements.
