Zenner Gas S.r.l. offers innovative solutions in remote meter reading (AMR) and remote management (AMM) systems.

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’.

       Comply with European standards EN1359 and OIML R137

       Comply with Italian standard UNI-TS 11291 

       Pressure and Temperature sensors that can be replaced in situ by authorised              personnel

       Remote Firmware update 

       Metrology battery:>8 years (opt. > 16) 

       Communication battery:>4 years (opt. > 8) 

       Can be installed in ATEX area, Zone 1 

       Optical interface for configuration 

       Integrated GPRS/GSM/SMS communicator 



Zenner Gas made MINI LEVEL, a revolutionary product that CHANGES remote meter reading for LPG tanks.

Devices are AUTOINSTALLED, which makes activation and implementation simpler. Its excellent operation autonomy, remote parametrisation and the chance to change software remotely turn this into an extremely flexible and unique product that can be easily adapted to all the remote meter reading applications for LPG tanks.

Only two screws are needed to fasten a MINI LEVEL directly onto the mechanical level indicator included in any buried or above-ground tank. INSIDE a MINI LEVEL you will find the technology of our well-known SPA sensor to measure the level of a tank.

MINI LEVEL uses GSM/SMS/GPRS technologies. It can be installed without any distance constraints.

MINI LEVEL is managed by the innovative TEKGAS service that offers everyone an

advanced remote meter reading tool.

At the same time, it is easy to use, available anywhere and easily integrated with all

kinds of management systems.

The system is based on the use of WEB technology, thus guaranteeing a high level of

reliability, availability and information confidentiality.

The management software can be accessed via INTERNET by means of the TEKGAS app.



It monitors the alarm for the system pressure, temperature and consumption if there is a meter equipped with a pulse emitter.

It intercepts the alarm of the double-level (minimum and maximum) pressure gauge and sends pressure and temperature data at the moment of the alarm.

Powered by a lithium battery. It controls one BF pulser, 1 pressure gauge, 1 temperature sensor, 2 Min-Max alarm NC inputs.

It can be supplied complete with pressure transducer, temperature sensor (with specific holder), pressure gauge with double alarm level (minimum and maximum) and pulser.

The device can be installed in a ZONE II because it is certified as: II 3G Ex nA nL IIB T2



Applications LPG tanks: electronic shut-off valve system.

The entire system is intended to allow access to the GPL storage reservoir valve only to authorized personnel.

The electronic lock is screwed on the load valve. The lock is activated by a hardware and software system that allows local operations (tank) to be monitored and managed remotely via GPRS connection to a WEB platform.

Lock locking/unlocking operations are carried out using an electronic key and a mobile phone. The key can be activated and deactivated by remote system.

The system only works if the lock is correctly screwed on the valve of the tank, this is possible because the system receives the consent of the operation following the unique code identification of the tank placed on the loading valve and contained in the Tag NFC.

All operations are logged on the local database and on the remote system database according to the following information content:





PULSAR-40 is the new volume converter by Zenner Gas S.r.l. PULSAR-40 is designed for remote meter reading in residential and industrial environment. It uses GPRS/GSM/SMS technologies. ATEX-certified, it can be directly installed in a ZONE 1 hazardous area.

PULSAR-40 complies with UNI TS11291 and Italian Regulatory Order ARG/gas/155/08. It is compatible with any Central Access System (SAC) that uses the CTR protocol. PULSAR-40 can be also managed by the innovative TekGas service, Zenner Gas SAC, that offers everyone an advanced remote meter reading and remote management tool that, at the same time, is easy to use.

TekGas can be accessed via INTERNET.
