Blocker-04 G2,5 - G4 Regulatory Order 155 et seq


...It is the first SMART METER with the unique electronic counter made in Italy in compliance with the Regulatory Order ARG/gas 155/08 and covered by international PATENTS.

Just by means of a mobile phone, these devices get AUTOINSTALLED and all activities related to activation, implementation and registration to the SAC are similar to those associated to changing a conventional meter. Its excellent operation autonomy and remote parametrisation, combined with the safe reliability of validated and tested mechanics throughout decades of operation, turn this into an extremely flexible product that can be easily adapted to mass-market gas-metering applications.

BLOCKER-04, although being totally new, ensures total measurement reliability thanks to the seamless integration of the most advanced electronics and the most consolidated mechanic tradition.

BLOCKER-04 uses Point-to-point GSM/SMS technologies.

It can be installed anywhere, without distance constraints or network ‘tuning’ problems

because it uses the GSM universal standard and the CTR standard transmission

protocol as its communication ‘INFRASTRUCTURE’.

Kit to protect a BLOCKER meter

It consists of a PVC protection to be applied onto a Blocker device or any other meter (Pat. Pending). 

It protects against water infiltrations and can be used together with the protective case that is compulsory by law.




The kit for pulsers has a reed emitter of pulses (cable 50 cm) and a support to fasten it to the meter.

Available in versions for the most typical types of meters:

Samtech/Samgas, NuovoPignone/Dresser, Sacofgas, Elster/Elkrogas, Fiorentini.

The device can be installed in a ZONE I because it is certified as:

II 2G EEx mb II B T6
