摘要： An apparatus for installing and removing a flow restrictor from a differential pressure measurement device with a seal housing attached to the differential measurement device. The seal housing being sealed to the fitting opening and having a channel connecting the fitting opening and a housing opening. The seal housing has first, second and third seals spaced along the channel. The distance between the first and third seals is greater than the height of the flow restrictor. The first, second and third seals are retractable between an extended, sealing position and a retracted, open position. At least one bleeder valve is positioned between the first and third seals for equalizing pressure between the channel and an external pressure. A series of rotating drivers are spaced along the channel and move the flow restrictor along the channel between the receptacle in the fitting and the housing opening of the seal housing.
