Abstract
An arrangement for controlling and measuring flow. The arrangement includes a fluid control barrier and a flow-measuring apparatus upstream of the fluid control barrier. The fluid control barrier includes a pair of plates for opening and closing a pipe, and the plates are movable towards a center line of the pipe to open the pipe and produce a symmetrical flow profile for the flow-measuring apparatus.
