Abstract

A purge manifold for mounting between a source of pressurized process fluid and an instrumentation manifold is described. The purge manifold includes a manifold body and various passageways therein including a purge fluid inlet, process fluid inlet(s) and test and bypass valves. In the most preferred use of the invention the purge manifold is mounted directly to an instrumentation manifold, winch instrumentation manifold is fluidly coupled directly to a differential pressure transmitter. The purge manifold permits introduction of a purging fluid to evacuate the passageways of the purge manifold and force the process fluid at least towards the taps of the source of process fluid.
