ABSTRACT:
An orifice meter comprising a gate valve type of body with an oval body band clamped between a pair of parallel plates. A gate-like carrier slides between the plates and carries an orifice disc with seal ring surrounding it. The seal rings seal around the flow passage and the orifice disc is large enough to be held place by engagement with the adjacent wall plate. In a more remote position, the seal rings may seal around an access opening, which is larger than the orifice disc so that by removing a closure plate, the orifice disc can be rapidly replaced.
