ABSTRACT:
A modular orifice meter construction comprising a main housing wherein an orifice disc carrier is positioned to seal around axially aligned flow tubes. A service housing with an access opening for replacement of orifice discs may be bolted into the main housing. A closure for said access opening is pivoted to the service housing and is normally held closed by a wedging clamp lock. A pinion rotatably mounted on the service housing raises and lowers the orifice disc carrier by engagement with a rack on the carrier. An isolating gate valve may be mounted between the main and service housings.
