Rosemount 305 Integral Manifold

The Rosemount 305 Integral Manifold attaches directly to the patented Rosemount Coplanar™ transmitter, eliminating the need for a flange. This lightweight, premier manifold comes in a 2-, 3- and 5-valve configuration and allows instrument isolation, controlled venting and added protection from leaking to ensure measurement integrity. This product can be factory-assembled to a transmitter and leak-tested and can be used with multivariable, static and differential pressure transmitters.
