ABSTRACT:
Apparatus for sampling fluid flow in a plurality of passages comprises a conduit connected to the passages. A device is movable along the conduit to connect a selected passage to the conduit and allow flow from the passage through the device and conduit to test equipment which may be external to a vessel containing the passages. In one arrangement normally-closed valves are associated respectively with the passages and the movable device opens the valve of the selected passage. In an alternative arrangement which obviates the need for valves, a flexible pipe in the conduit may be used to pull the device, the flow being along the pipe.
