MID energy meter and measurement system
GridVis® is a comprehensive and scalable piece of software for setting up an energy monitoring system and monitoring the power quality. It is used to both program and configure many UMG measuring devices, as well as to read, process and analyse the measured data. Typical applications are energy supply, industrial systems, facility management, etc.
In order to record work values securely and precisely for individual consumers, the UMG measuring devices have an extensive selection of tariffs of up to 14 items depending on the device type. Of course, they differentiate between effective energy (consumption, supply and without backstop) and reactive energy (inductive, capacitive and without backstop). This can be used to record high and low tariffs separately for example.
MID stands for the English term "Measuring Instruments Directive" and is the equivalent of the German term "Messgeräte-Richtlinie". This refers to the measuring instruments directive 2004/22/EC of the European parliament and the council dated 31st March 2004. The aim of the MID is a harmonised European market for measuring devices with a uniform approval process.
Areas of application
Save money with fair and precise cost assignment
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.
The electronic energy meters are suitable for the measurement of effective and reactive energy consumption. The measurement is designed for 1-phase and 3-phase systems with a voltage of L-N 230 VAC ±20 %. The current inputs are designed for either direct connection or measurement via a current transformer.
The installation is implemented via DIN rails, where special value is placed on the extraordinarily compact construction. All meters can be lead-sealed. Effective energy and reactive energy are available in one tariff or two tariffs and in four quadrants. The accuracy of the meter is class 1 for effective energy and class 2 for reactive energy.
All meters save the meter readings to non-volatile memory. The meter reading cannot be reset in the MID version.
