Gas Meter 2.0

3,500 tonnes of greenhouse gas emissions avoided/year

A meter that, in addition to measuring consumption in real time, identifies any anomalies and catches micro gas leaks that are hard to locate.

The innovation proposed by Hera includes a gas meter for residential users, based on innovative logic. The current equipment, envisaged by Arera Resolution 554/2015, can cut off the supply of gas to users, but cannot check whether there are dangerous gas supply conditions.

In addition to normal consumption measurement, Hera's new Gas Meter 2.0 can check the supply system's operating conditions of and act independently or under user control if it detects an anomaly. The anomaly can be caused by a seismic movement or by abnormal network conditions of a user's internal system or the city distribution system.

By monitoring the delivery pressure and flow rate data, the device can shut off the gas flow through its solenoid valve. After correcting the situation, the device can test the user's system for proper operation to support prompt service resumption.

Gas Meter 2.0 can cut off the flow of gas and secure the user's system:

  • if major seismic events occur;
  • in the event of sudden major leaks;
  • if it detects small latent leaks.

The benefits fall within these areas:

  • safety and reduction of accidents (including those caused by faults in the network downstream of the meter and the users' equipment that may be affected by gas meter 2.0);
  • civil protection for earthquake risk (mitigation of fire and explosion risk thanks to the immediate, targeted and timely shut-off of damaged gas user equipment);
  • quality of service (measurement of network and supply pressure, possibly correcting measured volumes also based on pressure values);
  • protection of the environment and reduction of greenhouse gas emissions (by eliminating micro-leaks, which overall in the service area generate significant atmospheric emissions and can be estimated at 3,500 tonnes of greenhouse gas avoided per year).

Once the development phase is over, in 2019 we will begin to manufacture these devices and perform the first installations for residential users. 300 thousand installations planned by 2022.
