the solutions implemented on the equipment to assure safety comply with the requirements set forth by the reference
standard in force (UNi/tS 11291). in detail, access:
• changing the text of the electronics as follows is not possible without removing the mechanical metrological seals and
without causing permanent damage to the metrological cover, in accordance with that described in the legalisation
plan indicated in the type examination certificate (MID) of the meter;
• to the memory device is not possible without permanently and patently damaging the equipment;
• to the flow shut-off valve (optional) and the temperature sensor is not possible without permanently and patently
damaging the equipment;
• to the metrological battery pack (not replaceable) is not possible without removing the mechanical and metrological
seal and without permanently damaging the metrological cover;
• to the communication battery pack (replaceable) is not possible without compromising the screw cover seals and
without leaving a trace of the event in the relevant memory register (metrological Events Log) of the equipment.
the attempts:
• to tamper with proper operation of the meter are detected and recorded in the metrological Events Log;
• by unauthorised personnel to access the meter through the communication channels which it is equipped with are
detected and recorded in the metrological Events Log;
• to access the meter through the communication channels made with wrong passwords or encryption keys are de-
tected, listed and made available to the control centre.
NOTICE!
• The interface equipment usually available to the user can only be used to read the data and it is not
possible to perform any configuration;
• The configurations that can be performed through the communication channels which the device is
equipped with – which can only be carried out by authorised personnel – leave a track since they are
stored in the appropriate memory log (Metrological Events Log).
Furthermore:
• the commands sent by external devices through the communication channels which the device is equipped with are
verified in terms of source authenticity;
• the messages transmitted through the communication channels conveying sensitive information are all efficiently
encrypted;
• the duration of the conditions is monitored and recorded by the firmware.
