ABSTRACT:
A measurement gauging device for an orifice meter having a restricting orifice plate, and pressure tap holes through the meter tube flanges, or through the orifice plate holding device (commonly called an orifice fitting), each side of the orifice plate to measure differential pressure through the meter tube. The measurement gauge includes a shank receivable through and rotatable in each of the pressure tap holes. An arm is moveable about an axis passing through and perpendicular to the shank. A mechanism is provided to move the arm between an extended position perpendicular to the shank and a retracted position substantially parallel to the shank wherein rotation of the shank while the arm is perpendicular will rotate the arm radially within the meter tube.
