Deregulation in the energy market
and the constant increase in electrical
energy costs have led to a fast growing
demand for fiscal metering. A flat rate
of energy consumption for each shop
in a shopping mall, or for each tenant
in a residential building, has become
unacceptable: either the provider or
the user could lose money, so both
of them require a “certified” value of
energy used. In 2006 the European
Union released a Measuring Instrument
Directive (called MID), involving a
number of metering issues, ranging
from energy to water, from taximeters
to exhaust gas meters.
The scope of this directive was to
guarantee to the users a high level of
safety and reliability in the measuring
instruments, protected against data
corruption, whilst at the same time
ensuring the free circulation of certified
measuring instruments within the EU.
For years Carlo Gavazzi has been
providing a whole range of MID-
certified energy meters, for all
requirements in any 1-phase or
3-phase application, either by direct
current measurement or by current
transformers. These range from the
simple, compact single phase EM110
and EM111 up to the advanced EM24
and EM26 for 3-phase systems.
Carlo Gavazzi is one of the first energy
meter manufacturers to have an internal
MID-approved Test Laboratory, from
which the instruments are supplied,
certified and sealed, ready for the
installation.
All the data can be aggregated and
therefore analysed and shared among the
tenants using the new web-server solutions
