Patent
·
OSTI ID:7180100
This patent describes a pressure monitoring device isolator for a pressure sensor capable of measuring the pressures of fluid in a pipeline. It comprises: an annular member axially interposable in the pipeline for measuring the pressure of fluid in the pipeline. The annular member having a central passage through which fluid in the pipeline passes; an annular sensing fluid chamber and an annular seal member separating the sensing fluid chamber from the central passage. The annular sensing fluid chamber being surrounded by the annular member and having sensing fluid therein; an opening in the outer periphery of the annular member, the opening being adapted to receive a pressure monitoring device; a sensing fluid passage extending radially inward in the annular member from the radially inner end of the opening; means for preventing significant loss of sensing fluid through the opening when the pressure monitoring device is removed from the opening; a valve member; and a seal ring.
