6.2.3 Meters subject to metrology
After verification to MID Annex MI-001 or the OIML R49, hardware and software components that
are critical for measurement characteristics and metrologically important parameters need to
be protected against intervention such as accidental or intentional corruption during operation.
If the meter has been verified to MID Annex MI-001, access to the programming menu of the
software containing the metrologically relevant parameters is blocked at the factory after the
Module D verification procedure:
• Menu number 1 (access control) is set to 1
• Metrological seals are placed
Access to the service menu, without breaking the metrological seals is possible by placing the
jumper. Parameters subject to fiscal metering are not available via the service menu.
The software version, diameter and meter constant are fiscal parameters. These values can be
read on the display and checked with the values on the name plate without breaking the sealing.
For more information please refer to
Show software version, diameter, meter constant and
display test on the display on page 36.
6.2.4 Metrological seals
After a meter is verified to MID Annex MI-001 or the OIML R49, the following metrological seals
are applied on:
• The access hole to the reset switch that allows access to the parameter settings.
• The electronic units against removal from the outer housing of the water meter.
• The name plate and the housing of the meter to secure the nameplate against removal.
INFORMATION!
Breaking the metrological seals could mean that the meter needs to be re-verified. For detailed
information, please check your local regulations.
