摘要： An apparatus for automatic leak detection includes a fixture having a primary seal and a secondary seal. The fixture connects to a workpiece to enclose a test volume defined in the workpiece. The seals are to interface with the workpiece to at least partially enclose a buffer volume. An enclosure is to connect to the fixture to enclose a test portion of the workpiece to form a test chamber. The secondary seal separates the buffer volume from the test chamber. The test volume and the test chamber have a tracer gas pressure differential between them. A port in fluid communication with the buffer volume removes fixture leakage from the buffer volume. A detector detects the tracer gas in the test volume or the test chamber where the tracer gas pressure differential between the test volume and the test chamber urges workpiece leakage of the tracer gas to accumulate.

摘要： Presented herein are systems and methods directed to a multispectral absorption-based imaging approach offering improved detection, localization, and quantification of gas emission. The imaging technology described herein utilizes an optical sensor and broadband illumination in combination with specialized reflector installments mounted about the site. The optical sensor detects light (e.g., reflected) from locations along the reflector installment. Lines-of-sight from the optical sensor to locations along the reflector installment sweep out an "optical curtain" partially enclosing and/or forming a boundary near various assets to be monitored. Optical absorption signatures from leaking gas crossing the optical curtain can be used to detect, localize, and obtain quantitative measures characterizing the leak. Measurements from reflector installments can be combined with measurements obtained via reflection of ambient light from background materials in a hybrid approach that expands monitoring capabilities and offers improvements in detection.
