About Us


ZENNER Gas S.r.l. was established in 2006 when a division boasting a ten-year experience in the market was purchased in order to best meet the new requirements of the energy market. 

The ZENNER Gas S.r.l.  quickly became a reference name for remote meter reading and remote management products and services. So much so that they played a leading role in the Smart Meter Roll Out national plan set by AEEG (the Italian Regulatory Authority for Electricity and Gas) in compliance with the 2020 deadline imposed by the European Union.

From the first level detectors for LPG tanks and the first transmitters to remotely read traditional gas meters to the first series of ‘smart’ gas meters that can remotely ‘open’ and ‘close’ meters, ZENNER Gas technological progress has marked the history of household Gas Smart Meters in Italy.

Corporate History


ZENNER Gas is present throughout Italy with tens of thousands of meters installed

  • It also offers the SAC service with the WEB TekGas platform.
  • It gives technical support to customers via its Service Centre that promotes, from a customer-oriented viewpoint, new ways of managing data, contacts and relationships.

The old ‘lock’ is adapted to the ‘digital’ era. 

The iLock system was created to control the filling valve in LPG tanks


ZENNER Gas introduces a new range of electronic gas meters addressed to industrial users.


ZENNER Gas introduces the first Italian household smart gas meter

MID-certified and in accordance with Italian Regulatory Order ARG/gas 155/08: The Blocker-04.


The Blocker: The ‘father’ of all modern smart gas meters.

In 2007, when gas meters were quite different from the ones known today, ZENNER Gas was already present in the gas metering world with the Blocker.


TekGas WEB platform

In 2006, the TekGas WEB platform was the tool used to provide remote meter reading and remote management services. TekGas was the first to use the system that today is called SAC or Central Access System.
