Safety monitoring systems and methods include a mesh communications network and an EVC (Electronic Volume Corrector) installed in one or more gas distribution components and/or industrial metering components in a gas distribution station and/or an industrial metering station. A group of sensors can be configured, which includes, for example, a gas leak sensor, a pressure transducer, a temperature transducer, an intrusion sensor and/or other types of sensors. Such sensors can be located within the gas distribution station and/or industrial metering station. The sensors communicate wirelessly with the EVC and the gas distribution and/or industrial metering components through the mesh communications network.
