IMPORTANT NOTICE

This installation guide provides basic guidelines for Rosemount

485 Annubar. It does not provide instructions for configuration, diagnostics,

maintenance, service, troubleshooting, Explosion-proof, Flame-Proof, or

instrinsically safe (I.S.) installations. Refer to the 485 Annubar reference

manual (document number 00809-0100-4810) for more instruction.

This manual is also available electronically on www.rosemount.com.

If the 485 Annubar was ordered assembled to a Rosemount 3051S

transmitter, the new assembly is the Rosemount 3051SFA Probar Flowmeter.

See the following Quick Installation Guide for information on configuration

and hazardous locations certifications: Rosemount 3051S Series Pressure

Transmitter (document number 00825-0100-4801).

If the 485 Annubar was ordered assembled to a Rosemount 3095MV

transmitter, the new assembly is the Rosemount 3095MFA Mass Probar

Flowmeter. See the following Quick Installation Guide for information on

configuration and hazardous locations certifications: Rosemount 3095MV

(document number 00825-0100-4716).

WARNING

Process leaks may cause harm or result in death. To avoid process leaks,

only use gaskets designed to seal with the corresponding flange and o-rings

to seal process connections. Flowing medium may cause the 485 Annubar

assembly to become hot and could result in burns.

STEP 1: LOCATION AND ORIENTATION

Correct orientation and straight run requirements must be met for

accurate and repeatable flow measurements. Refer to Table 1 for

minimum pipe diameter distances from upstream disturbances.

NOTE

• For gas service, multiply values from Table 1 by 1.5.

• Consult the factory for instructions regarding use in square or

rectangular ducts.

• “In Plane A” means the bar is in the same plane as the elbow.

“Out of Plane A” means the bar is perpendicular to the plane of

the elbow.

• If proper lengths of straight run are not available, position the

mounting such that 80% of the run is upstream and 20% is

downstream.

• Use straightening vanes to reduce the required straight run

length.

• Row 6 in Table 1 applies to gate, globe, plug, and other

throttling valves that are partially opened, as well as control

valves.

Misalignment

485 Annubar installation allows for a maximum misalignment of 3°.

Horizontal Orientation

For proper venting and draining, the sensor should be located in the

upper half of the pipe for air and gas applications. For liquid and steam

applications, the sensor should be located in the bottom half of the

pipe.

Vertical Orientation

The sensor can be installed in any position around the circumference

of the pipe provided the vents are positioned properly for bleeding or

venting. Optimal results for liquid or steam are obtained when flow is

up. The preferred orientation for air or gas is flow down, but upwards

flow is acceptable. For steam applications, a 90° spacer will be added

to provide water legs to ensure the transmitter stays within

temperature limits.

STEP 2: WELD MOUNTING HARDWARE

NOTE

Rosemount-supplied mounting includes critical alignment hardware

that assists in the correct drilling of the mounting hole. It also assists in

the alignment of the sensor to the mounting hole for insertion.

1. At the pre-determined position, place the thread-o-let on the pipe,

gap 1/16 in (1.5 mm), and place four 1/4-in. (6-mm) tack welds at 90°

increments.

2. Check alignment of the mounting both parallel and perpendicular to

the axis of flow (see Figure 7). If alignment of the mounting is within

tolerances, finish weld per local codes. If outside of specified

tolerance, make adjustments prior to making the finish weld.

3. To avoid serious burns, allow the mounting hardware to cool

before continuing.

STEP 3: INSTALL ISOLATION VALVE

1. Thread the guide nipple into the mounting.

2. Thread the isolation valve onto the guide nipple. Ensure that the

valve stem is positioned so that when the Flo-Tap is installed, the

insertion rods will straddle the pipe and the valve handle will be

centered between the rods (see Figure 8). (Note: Interference will

occur if valve is located in line with the rods.)

Figure 8. Isolation Valve Orientation

STEP 4: MOUNT DRILLING MACHINE

Drilling Machine is not provided with assembly.

1. Determine the sensor size based on the probe width (see Table 2).

2. Mount the drilling machine to the isolation valve.

3. Open the valve fully.

4. Drill the hole into the pipe wall in accordance with the instructions

provided by the drilling machine manufacturer (use Table 2 to

select the proper drill bit for the sensor being used).

5. Retract the drill fully beyond the valve.
