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, Flameproof, or Intrinsically 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, 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 3095 transmitter, see the

following Quick Installation Guide for information on configuration and hazardous

locations certifications: Rosemount 3095 (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.

CAUTION

If pipe/duct wall is less than 0.125-in. (3,2 mm) use extreme caution when installing

sensor. Thin walls can deform during welding, installation or from the weight of a

cantilevered flowmeter. These installations may require a fabricated outlet, saddle or

external flowmeter support. Please consult factory for assistance.

STEP 1 CONTINUED...

NOTE

• Consult the factory for instructions regarding use in square or rectangular ducts.

• “In Plane A” means the sensor is in the same plane as the elbow. “Out of Plane A”

means the sensor 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°.

STEP 1 CONTINUED...

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. The maximum temperature for a direct mounted transmitter is

500 °F (260 °C).

NOTE:

For steam applications with DP readings between 0.75 and 2 inH2O in horizontal pipes, it is

recommended to install the primary element / flowmeter mounting above 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. For steam applications, a 90° spacer will be added to provide

water legs to ensure the transmitter stays within temperature limits. The maximum

temperature for a direct mounted transmitter is 500 °F (260 °C).

STEP 2: DRILL HOLES INTO PIPE

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

2. Depressurize and drain the pipe.

3. Select the location to drill the hole.

4. Determine the diameter of the hole to be drilled according to the specifications in Table 2.

Drill the mounting hole into the pipe with a hole saw or drill. DO NOT TORCH CUT THE

HOLE.

Table 2. Sensor Size / Hole Diameter Chart

5. If opposite-side support model is supplied, a second identically sized hole must be drilled

opposite the first hole so that the sensor can pass completely through the pipe. (To

determine if you have an opposite-side support model, measure the distance from the tip

to the first slot or hole. If the distance is greater than 1-in. (25,4 mm), it is the

opposite-side support model.) To drill the second hole, follow these steps:

a. Measure the pipe circumference with a pipe tape, soft wire, or string. (For the most

accurate measurement the pipe tape needs to be perpendicular to the axis of flow.)

b. Divide the measured circumference by two to determine the location of the second

hole.

c. Re-wrap the pipe tape, soft wire, or string from the center of the first hole. Then, using

the number calculated in the preceding step, mark the center of what will become the

second hole.

d. Using the diameter determined in step 3, drill the hole into the pipe with a hole saw or

drill. DO NOT TORCH CUT THE HOLE.

6. Deburr the drilled holes on the inside of the pipe.

STEP 3: ASSEMBLE AND CHECK FIT-UP

For accurate measurement, use the following steps to ensure that Ports A and B are equal

distances from the inside walls of the pipe.

1. Assemble the 485 to the mounting hardware with the gaskets and bolts.

2. Hand tighten the bolts just enough to hold the position of the sensor centered in the

mounting hardware.

3. Measure the distance from the high point of the weldolet to the first sensing hole, port B,

then subtract 1/16-in (1,6 mm).

4. Measure the distance from the end of the transferred length in step 4 to the last sensing

hole, port A.

5. Compare the numbers obtained in steps 3 and 4.

Small discrepancies can be compensated for with the fit-up of the mounting hardware. Large

discrepancies may cause installation problems or error.

STEP 4: WELD MOUNTING HARDWARE

1. Center the flanged assembly over the mounting hole, gap 1/16-in. (1,6 mm), and measure

the distance from the outer diameter of the pipe to the face of the flange. Compare this to

Table 3 and adjust the gap as necessary.

Table 3. Flange Sizes and ODF Per Sensor Size

2. Place four 1/4-in. (6 mm) tack welds at 90° increments. Check alignment of the mounting

both parallel and perpendicular to the axis of flow (see Figure 9). If alignment of the

mounting is within tolerances, finish weld per local codes. If alignment is outside of

specified tolerance, make adjustments prior to making the finish weld.

Figure 9. Alignment

3. If opposite-side support is being used, center the fitting for the opposite side support over

the opposite side hole, gap 1/16-in. (1,6 mm), and place four 1/4-in. (6 mm) tack welds at

90° increments. Insert the sensor into the mounting hardware. Verify that the tip of the

sensor is centered in the opposite side fitting and the plug will fit around sensor. Finish

weld per local codes. If alignment of the sensor does not allow enough clearance to

insert the opposite side plug, make the necessary adjustments prior to making the finish

weld.

4. To avoid serious burns, allow the mounting hardware to cool before continuing.
