Mechanical wide-range gas meter

The feature that makes this meter unique is its ability to operate correctly in a wide range of flow rates and enables precise measurement from  Qmin 0,016 m3/h. This allows to replace the conventionale G1,6 - G2,5- G4 using only one meter: WG2,5S. The advantage is to measure the gas even at the flow rates where the other domestic can not do it.

These characteristics , combined with stable and constant performance over time, have been achieved thanks to the use of first choise materials and innovative patented solutions. The integrated calibration system coordinates the movement of the valve in relation to the optimum gas flow. The excellent linearity of the error curve is guaranteed even at low flow rates.

thanks to the use of high-grade materials the diaphragm gas meter is particularly resistant to corrosion therefore suitable for various gas media.

The Atmos diaphragm gas meter meets the requirements of the MID, EN1359 and OIML R137 1&2:2012.

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’.

G10 - G16 - G25 "SMART" GAS METER Regulatory Order 155 et seq


These Smart 155-compliant meters use Point-to-Point GSM/SMS/GPRS technologies. They can be installed anywhere without distance constraints or network ‘tuning’ problems because they use the GSM/SMS/GPRS universal standard and the CTR standard transmission protocol as their 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
