MID - Declaration of Conformity
Multidata WR3 is produced and
tested in compliance with the
European Measuring Instruments
Directive (MID). According to this
directive, devices are no longer
carrying an initial verication
stamp, but rather the year of the
device’s declaration of conformity
(recognizable on the front of the
device, for example: M19=2019).
Only valid for Germany:
The metrological part for cooling
energy is calibrated acc. to guide-
line PTB K7.2.
The MID controls the use of mea-
suring devices up to the moment
they are placed on the market
resp. their rst putting into use.
Aer this, the national regulations
for devices subject to compulsory
verication apply within the EU.
The duration of initial verication
validity in Germany remains 5
years for heat meters. Aer this
period has expired, the measuring
device may no longer be used for
billing in commercial use. The reg-
ulations resp. validity period may
vary in other countries of the EU.

ment. The latest information about
