  • Publication number: 20230160867
    Abstract: A system includes a gas detector to detect a gas leak and notify a gas meter of a gas level of the gas leak. The gas meter receives the notification about the gas leak from the gas detector, and compares the gas level detected by the gas detector with a threshold level. The gas meter determines if the detected gas level is greater than the threshold level to determine whether to turn off a gas valve due to the detected gas level. The system also includes a head end system configured to receive notification of the detected gas level and status of the gas valve from the gas meter.

  • Patent number: 11356753
    Abstract: A utility meter includes a metrology core, a short-range radio configured to communicate wirelessly over a local area mesh network, a long-range radio configured to communicate wirelessly over a wide area network and a controller that checks a performance of the local area mesh network against one or more predetermined performance criteria. When the performance of the local area mesh network meets a set of one or more predetermined performance criteria, the utility meter communicates a first set of the information to the head-end system using the short-range radio. When the performance of the local area mesh network does not meet the set of one or more predetermined performance criteria, the utility meter communicates a second set of information to the head-end system using the long-range radio.

  • Patent number: 10271381
    Abstract: Methods and systems for integrating communication devices into an industrial wireless system. A communications interface can be enabled on a field device access point from a user interface associated with a wireless device manager. The field device access point is configured to enable registers to read from different slave devices at different speeds and different data types. A proxy object can be implemented, which communicates with RTU (Remote Terminal Unit) devices and a cache can be implemented to store read data from different RTU slave. The read data is then periodically published to the wireless device manager through a wireless interface, thereby permitting the RTU devices or TCP devices to connect to the industrial wireless network using the field device access point.
