ABSTRACT:
A device and method are shown for detecting leaks in the differential pressure measuring passageways of an orifice meter tube. A body having a threaded end region is inserted within the differential pressure measuring passageway to be tested. A stem is slidingly received within an internal bore provided in the body when the body is engaged within the passageway. The stem has an exposed end which extends externally from the body and an inner end which is insertable through the internal bore of the body and into the passageway to be tested. A packing cap seals the region of the internal bore adjacent the exposed end of the stem and a deformable seal located on the inner end of the stem is actuated by manipulating the stem exposed end to seal off the opening of the passageway into the orifice meter tube. A test port located on the body communicates with the internal bore of the body for connection of vacuum testing equipment to test the integrity of the passageway.
