Abstract
A removable orifice plate device includes a body having an un-threaded portion which includes a groove. An orifice plate receiving slot bisects the groove and extends partially through a body diameter. An orifice plate having an orifice slides into the orifice plate receiving slot with an orifice central axis co-axially aligned with a longitudinal axis of the body at an orifice plate installed position in the orifice plate receiving slot. A tab integrally extends from the orifice plate and is oriented perpendicular to a body of the orifice plate. The tab includes an indicator symbol, the indicator symbol visually identifying a predetermined size of the orifice. A transparent indicator sleeve is slidably disposed on a body outer surface and is axially slidable between a first position covering the groove to a second position exposing the groove. The indicator symbol is visible through the indicator sleeve in the first position.
