Device for reading and controlling gas supply and its operating method

A device for reading and controlling a gas supply, comprising:

• an input connector and an output connector of a pipe in which gas flows from a distribution network towards at least one residential user;
• a control logic unit for the operation of the device;
• a plurality of sensors operationally connected to the control logic unit for measuring values of physical quantities;
• and
• a gas supply blocking member operationally connected to the control logic unit,
• wherein the control logic unit includes:
• a threshold value access module configured to receive, from an archive, first predetermined threshold values and/or second predetermined threshold values;
• a first comparison module configured to compare the values measured by the plurality of sensors with the first predetermined threshold values;
• a recording module, operatively connected to the plurality of sensors configured to record one or more time series of the values measured by each sensor of the plurality of sensors;
• a processing module configured to process the one or more time series recorded by the recording module;
• a second comparison module configured to compare the one or more time series with the second predetermined threshold values;
• an interruption module configured to send an alarm signal and activate the gas supply blocking member to block the gas supply, when the measured values are higher than the first predetermined threshold values;
• and
• a reopening module configured to send an inhibition command of the gas supply blocking member to inhibit the gas supply blocking member and allow the gas supply, when the measured values are higher than the first predetermined threshold values and when the values obtained from processing of the one or more time series by the processing module are lower than the second predetermined threshold values.
