Title: SENSING PRESSURE VARIATIONS IN PIPELINES
Abstract:
A pressure sensing device is operable to monitor pressure variations within a fluid pipeline. The pressure sensing device comprises a pair of complementary sensor elements. At least one of the sensor elements is mounted to a supporting bracket that is mounted to a point on the external surface of the pipeline. At least one sensor element is mounted such that the pair of complementary sensor elements experience relative displacement as the external surface of the pipeline undergoes changes in size or shape. The pair of complementary sensor elements are operable to detect said relative displacement and thereby provide an indication of pressure variation within the pipeline.
