Techniques for detecting and remediating a low gas pressure situation within a gas delivery system are described. In one example, a smart gas metering device measures gas pressure. The first device determines that the gas pressure value is less than a first threshold value, indicating a low gas pressure condition. The first smart metering device reports this condition to a second smart metering device, which may be nearby. In response, the first smart metering device receives gas pressure information from the second smart gas metering device. The first smart gas metering device then reports one of two conditions to a headend device, such as a main office server. In a first possibility, the report indicates a low gas pressure event confined to the first device. Alternatively, the report indicates a low gas pressure event within a distribution area comprising the first device and the second device.

Network edge detection and notification of gas pressure situation

Techniques for detecting a high gas pressure situation within a gas delivery system (e.g., for natural gas delivery to homes and businesses) are described. In one example, a device measures gas pressure. If a pressure over a threshold value is detected, a nearby device is messaged. The nearby device either confirms the over-pressure condition or indicates it may be more localized. If the condition is present within an area of the gas delivery system and/or within a group of devices within the gas delivery system, protective measures may be taken, such as closing valves providing gas to a number of service sites.

The leak detection system encompasses the use of a fluid monitoring device equipped with transmission capabilities and a data acquisition device. The fluid monitoring device monitors consumption of a fluid over a predetermined time period to obtain a consumption value. The fluid monitoring device then compares the consumption value against a pre-established threshold value. If the consumption value is less than the threshold value, the fluid monitoring device produces a leak indication. The fluid monitoring device transmits the leak indication, which is received by the data acquisition device.
