Abstract
An orifice meter with a pair of parallel, flat steel body plates. Flow tubes of predetermined sizes are welded in mounting rings to be bolted to the opposing body plates with the inner ends of the tube extending into the body space in alignment with the orifice disc. Wide grooves around the tubes ensure communication of pressure tap ports through the tube with lateral pressure tap ducts through the body plates. Ducts through the upstream body plate from the groove to the body space and through the downstream plate from the body space to the exterior, enable one, by removal of a plug, to flush the bottom of the body space with upstream pressure.
