  • Inspection ports for fluid flow measuring sections
    Patent number: 4967607
    Abstract: Inspection port plugs for fluid flow measuring sections are separated from the access and sealing flanges that have been employed in the past. This permits more accurate and faster positioning of the plug that is no longer vulnerable to faulty flange positions caused by flange gasket stiffness or bolt tightness.
