Ordering Information - Emerson Rosemount 304 Product Data Sheet

Rosemount Manifolds
Five-valve
The 5-valve configuration is available on Rosemount 305 and 304
Manifolds for use with differential pressure and multivariable
transmitters. Two isolate valves provide instrument isolation and
one equalize valve is positioned between the high and low process
connections. In addition, two drain/vent valves allow for controlled
venting, 100 percent capture of vented or drained process, and
simplified in-process calibration capability.

Five-valve natural gas
The 5-valve natural gas configuration is available on the
Rosemount 305 and 304 Manifolds for use with differential

instrument isolation and a single drain/vent valve allows for
controlled venting, 100 percent capture of vented or drained
process, and simplified in-process calibration capability. In
addition, two equalize valves provide extra protection from
leaking to ensure DP signal integrity.

Ordering information

Rosemount Manifolds can be ordered as a stand-alone product or
as an integrated assembly attached to a transmitter.
Stand-alone manifold
1. Reference the "Selection guide" on page 2
choosing the type of manifold.
2. Specify a completed model number by referencing the
applicable ordering table for the selected manifold type:
Rosemount 305 Integral Manifold, see

Rosemount 306 In-line Manifold, see

Rosemount 304 Conventional Manifold, see

Transmitter/manifold assembly
1. Specify a completed Rosemount transmitter model number
by referencing the applicable product data sheet.
2. Specify a completed manifold model number by referencing
the applicable ordering table for the selected manifold type:
Rosemount 305 Integral Manifold, see

Rosemount 306 In-line Manifold, see

Rosemount 304 Conventional Manifold, see

3. Verify the transmitter model number contains the correct
"Process Connection" code or "Manifold Option" code for
the desired transmitter manifold assembly (see
