Housing apparatus for sensitive gas sensor

A sensor housing apparatus includes a housing having an enclosure and outer assembly, at least one flow path extending through the housing, a gas sensor disposed in the enclosure and a thermal mass. The thermal mass is mounted within the enclosure in thermal communication with the gas sensor, and is configured to transfer thermal energy from the gas sensor to an ambient environment surrounding the housing and minimize temperature gradients adjacent the gas sensor.

Method of assembling a fugitive gas sensor enclosure

A gas sensor enclosure is provided. The gas sensor enclosure includes at least two coaxial shells, a gas sensor, a gas permeable membrane that exposes a portion of the gas sensor to gas exchange through one of the at least two coaxial shells and a screen. The screen encloses the at least two coaxial shells, the gas sensor and the gas permeable membrane.

Heuristic based analytics for gas leak source identification

Heuristic-based techniques for gas leak source identification are provided. In one aspect, a method for identifying a location of a gas leak source includes: obtaining gas sensor data and wind data synchronously from a gas leak detection system having a network of interconnected motes comprising gas sensors and wind sensors, with the gas sensors arranged around possible gas leak sources in a given area of interest; identifying the location of the gas leak source using the gas sensor data and wind data; and determining a magnitude of gas leak from the gas leak source using the location of the gas leak source and a distance d between the location of the gas leak source and a select one of the gas sensors from which the gas sensor data was obtained. A gas leak detection system is also provided.
