Abstract
A measurement tool and method for measuring the eccentricity of an orifice plate bore in a longitudinal bore of an orifice fitting is disclosed. The measurement tool includes a housing having a first and second plurality of radial bores. At least one ball is inserted in each of the pluralities of radial bores. A first and a second member are rotated to radially force the pluralities of balls outwardly of the housing against the longitudinal bore of the orifice fitting. A head assembly is attached to the housing. An insertion member having a tapered end portion is inserted in the orifice plate bore. A slide member is connected to the insertion member and is slidably mounted in the head assembly. A rod is slidably inserted through the housing and into the head assembly. An arm is pivotally mounted in the head assembly having a first surface in contact with the slide member and a second surface in contact with an end of the rod. An indicator gauge assembly contacts a second end of the rod.
