PLATE CARRIER GUIDE FOR AN ORIFICE FITTING

摘要

A device and method for positioning an orifice plate carrier in an orifice fitting. The positioning device is secured in an upper chamber of the fitting and includes an insert having a first end and a second end, and a back side, a first side, and a second side each extending from and connecting the first and second ends to form a through-passage with a front side. The through-passage is configured to allow the orifice plate carrier to pass therethrough. The first and second sides include a first cutout and a second cutout, respectively, which are configured to allow a gear to pass therethrough. The gear engages grooves on the orifice plate carrier to pass the orifice plate carrier through the upper chamber. The positioning device provides consistent and repeatable alignment in guiding the orifice plate carrier in and out of the fitting.
