Process Connections 3051S transmitter flange process connection size is

/4–18 NPT. Flange

adapters with

/2–14 NPT connections are available as the D2 option. Use

your plant-approved lubricant or sealant when making the process

connections. The process connections on the transmitter flange are on

/8-inch (54 mm) centers to allow direct mounting to a three-valve or

five-valve manifold. Rotate one or both of the flange adapters to attain

connection centers of 2-in. (51 mm), 2

/8-in. (54 mm), or 2

/4-in. (57 mm).

Install and tighten all four flange bolts before applying pressure to avoid

leakage. When properly installed, the flange bolts will protrude through the top

of the SuperModule housing. Do not attempt to loosen or remove the flange

bolts while the transmitter is in service.

To install adapters to a Coplanar flange, perform the following procedure:

1. Remove the flange bolts.

2. Leaving the flange in place, move the adapters into position with the

O-ring installed.

3. Clamp the adapters and the Coplanar flange to the transmitter module

using the longer of the bolts supplied.

4. Tighten the bolts. Refer to Table 2-1 on page 2-7 for torque

specifications.
