Common CGT-02 Series - Verification and Installation Seals

20
The original verification stamp seal is required for the gas meter to be considered
a legal measurement device.
Installation seals placed at the connectors of the pressure transducers (P7), HF emitters (P8),
temperature transducers (P9) and possibly at the mechanical output (P10), may feature stamps
placed by the manufacturer, gas supplier or authorized installer. In addition, installation seals
should be placed on the blinders (plugs) of unused electrical outputs and possibly
on the three-way valve connected to the volume converter (see section VIII.)
The original verification period depends on metrological regulations in the country
of installation. Before the expiration of the verification period, the gas meter should be
submitted for secondary verification in an authorized laboratory (viable turnaround time
for the verification procedure in a laboratory should be taken into account).
