ABSTRACT:
An orifice meter with an isolation valve plate pivotally suspended from the bottom of the orifice disc carrier. The valve plate is eccentrically mounted so that it drops to horizontal position when the carrier is raised free of the flow passage sealing surfaces, to seal off an upper chamber into which the disc carrier is raised. When again lowered, the valve plate engages a cam member which cams its back into vertical position nested in a recess along the bottom of the disc carrier.
