Rosemount 305, 306, and 304 Manifolds

The Rosemount 305 Integral Manifold mounts directly to the transmitter and is available in two styles:
Traditional and Coplanar. The traditional Rosemount 305 can be mounted to most primary elements
with mounting adapters in the market today. The Rosemount 306 In-Line Manifold is used with in-line
transmitters to provide block-and-bleed valve capabilities of up to 10000 psi (690 bar). The Rosemount
304 comes in two basic styles: Traditional (flange x flange and flange x pipe) and Wafer. The Rosemount
304 Traditional Manifold comes in 2-, 3-, and 5-valve configurations. The 304 Wafer Manifold comes in
3- and 5-valve configurations.
