2.1 Safety messages

Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Refer to the following safety messages before performing any operation in this section.

Section 2: Installation

September 2015

If pipe/duct wall is less than 0.125-in. (3.2mm) 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. Consult factory for assistance.

Explosions could result in death or serious injury.

 Do not remove the transmitter cover in explosive atmospheres when the circuit is live.  Before connecting a Field Communicator in an explosive atmosphere, make sure the

instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

 Verify the operating atmosphere of the transmitter is consistent with the appropriate

hazardous locations certifications.

 Both transmitter covers must be fully engaged to meet explosion-proof requirements.

Failure to follow these installation guidelines could result in death or serious injury.

 Make sure only qualified personnel perform the installation.

2.2 Receiving and inspection

Flowmeters are available in different models and with different options, so it is important to inspect and verify that the appropriate model was delivered before installation.

Upon receipt of the shipment, check the packing list against the material received and the purchase order. All items are tagged with a sales order number, serial number, and customer tag number. Report any damage to the carrier.

2.3 Considerations

2.3.1 Limitations

Structural

Structural limitations are printed on the sensor tag. Exceeding structural limitations may cause sensor failure.

Functional

The most accurate and repeatable flow measurement occurs in the following conditions:

 The structural limit differential pressure, as printed on the sensor tag, is not exceeded.

 The instrument is not used for two-phase flow or for steam service below saturation

temperature.

 Install the flowmeter in the correct location within the piping branch to prevent

measurement inaccuracies caused by flow disturbances.

 The flowmeter can be installed with a maximum misalignment of 3 degrees (see Figure

2-1). Misalignment beyond 3 degrees will cause flow measurement errors.

Reference Manual

00809-0100-4809, Rev DA

Figure 2-1. Permissible Misalignment

3° max. 3° max.

2.3.2 Environmental

Mount the flowmeter in a location with minimal ambient temperature changes. Appendix A:

Specifications and Reference Data lists the temperature operating limits. Mount to avoid

vibration, mechanical shock, and external contact with corrosive materials.

3° max.

Access requirements

Consider the need to access the flowmeter when choosing an installation location and orientation.

Installation

Reference Manual

00809-0100-4809, Rev DA

Process flange orientation

Orient the process flanges on a remote mounted flowmeter so that process connections can be made. For safety reasons, orient the drain/vent valves so that process fluid is directed away from technicians when the valves are used. In addition, consider the possible need for a testing or calibration input.

Housing rotation

The electronics housing may be rotated up to 180 degrees (left or right) to improve field access to the two compartments or to better view the optional LCD meter. To rotate the housing, release the housing rotation set screw and turn the housing up to 180 degrees.

Electronics housing

Terminal side

The circuit compartment should not routinely need to be opened when the unit is in service. Wiring connections are made through the conduit openings on the top or side of the housing. The field terminal side is marked on the electronics housing. Mount the flowmeter so that the terminal side is accessible. A 0.75-in. (19 mm) clearance is required for cover removal. Use a conduit plug on the unused side of the conduit opening. A 3-in. (76 mm) clearance is required for cover removal if a meter is installed.

2.5.4 Instrument manifolds

Figure 2-5 on page 10 identifies the valves on a 5-valve and a 3-valve manifold. Table 2-1 on page 10 explains the purpose of these valves.

An instrument manifold is recommended for all installations. A manifold allows an operator to equalize the pressures prior to the zero calibration of the transmitter as well as to isolate the electronics from the rest of the system without disconnecting the impulse piping. Although a 3-valve manifold can be used, a 5-valve manifold is recommended.

5-valve manifolds provide a positive method of indicating a partially closed or faulty equalizer valve. A closed faulty equalizer valve will block the DP signal and create errors that may not be detectable otherwise. The labels for each valve will be used to identify the proper valve in the procedures to follow.

2.5.6 Flowmeter orientation

Liquid

Due to the possibility of air getting trapped in the Annubar sensor, it should be located according to Figure 2-7 for liquid applications. It should be mounted between 15° to 45° from vertical down to ensure that air is vented from the Annubar sensor, and that sediment or solid particles are not collected within the Annubar sensor.

For liquid applications, mount the side drain/vent valve upward to allow the gases to vent. In vertical lines, the Annubar sensor can be installed in any position around the circumference of the pipe, provided the vents are positioned properly for bleeding or venting. Vertical pipe installations require more frequent bleeding or venting, depending on the location.

For a remote mounted transmitter, mount the transmitter below the process piping, adjust 10° to 15° above direct vertical down. Route the impulse piping down to the transmitter and fill the system with cool water through the two cross fittings.

Gas

Figure 2-8 illustrates the recommended location of the flowmeter in gas applications. The

sensor should be located on the upper half of the pipe, at least 45° above the horizontal line.

For gas applications, mount the drain/vent valve downward to allow liquid to drain. In vertical lines, the Annubar sensor can be installed in any position around the circumference of the pipe, provided the vents are positioned properly for bleeding or venting. Vertical pipe installations require more frequent bleeding or venting, depending on the location.

For a remote mounted transmitter, secure the transmitter above the Annubar sensor to prevent condensible liquids from collecting in the impulse piping and the DP cell.

Steam

In steam applications, fill the lines with water to prevent the steam from contacting the transmitter. Condensate chambers are not required because the volumetric displacement of the transmitter is negligible.

For a remote mounted transmitter, mount the transmitter below the process piping, adjust to 10° to 15° above direct vertical down. Route the impulse piping down to the transmitter and fill the system with cool water through the two cross fittings.

Top mounting for steam applications is an appropriate mounting option in many cases. Consult Rosemount Customer Central for instructions regarding steam on top mounting.

Note

For wet steam, do not mount the flowmeter at the direct vertical position. Mounting at an angle will avoid measurement inaccuracy due to water running along the bottom of the pipe.

2.5.7 Remote mounted transmitter

Instrument head connections differ between horizontal and vertical pipes. For horizontal lines, the instrument connections are parallel to the pipe and for vertical lines, the instrument connection are perpendicular.

Valves and fittings

Throughout the remote mounting process:

 Use only valves, fittings, and pipe thread sealant compounds that are rated for the

service pipeline design pressure and temperature as specified in Appendix A:

Specifications and Reference Data.

 Verify that all connections are tight and that all instrument valves are fully closed.

 Verify that the Annubar sensor is properly oriented for the intended type of service:

liquid, gas, or steam (see “Flowmeter orientation” on page 14).

Impulse piping

Impulse piping connects a remote mounted transmitter to the Annubar sensor. Temperatures in excess of 250 °F (121 °C) at the transmitter will damage electronic components; impulse piping allows service flow temperatures to decrease to a point where the transmitter is no longer vulnerable.

1. Consult with RCC to determine if this installation is right for your application.

The following restrictions and recommendations apply to impulse piping location.

 Piping used to connect the Annubar sensor and transmitter must be rated for

 Impulse piping that runs horizontally must slope at least 1-in. per foot (83 mm/m).

 With the Annubar mounted below the pipe, impulse piping must slope downwards

and heat tracing to prevent freezing.

 For installations where the transmitter is more than 6-ft. (1.8m) from the Annubar

sensor, the high and low impulse piping must be run together to maintain equal temperature. They must be supported to prevent sagging and vibration.

 Threaded pipe fittings are not recommended because they create voids where air can

become entrapped and have more possibilities for leakage.

 Run impulse piping in protected areas or against walls or ceilings. If the impulse piping

is run across the floor, ensure that it is protected with coverings or kick plates. Do not locate the impulse piping near high temperature piping or equipment.

 Use an appropriate pipe sealing compound rated for the service temperature on all

threaded connections. When making threaded connections between stainless steel fittings, Loctite

PST® Sealant is recommended.

5. If opposite-side support coupling 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 an opposite-side support model, measure the distance from the tip of the first slot or hole. If the distance is greater than 1-in. (25.4 mm), it is the opposite-side 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 from Tab l e 2 - 3, drill the hole into the pipe with a hole

saw or drill. Do not torch cut the hole.

Verify that the tip of the bar is centered in the opposite side fitting and verify that the plug will fit around bar. If the bar is centered in the fitting and plug fits around the bar, finish weld per local codes. If the alignment of the bar 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.

Step 4: Insert Annubar sensor

After the mounting hardware has cooled, use the following steps for installation.

1. Thread studs into the Pak-Lok body.

2. To ensure the flowmeter contacts the opposite side wall, mark the tip of the sensor with a marker. (Do not mark if the sensor was ordered with special-cleaned option code P2 or PA. )

3. Insert the flowmeter into the Pak-lok body until the sensor tip contacts the pipe wall (or support plug). Rotate the flowmeter back and forth.

4. Remove the flowmeter.

5. If opposite-side support coupling 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 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 from Ta b l e 2 -4 , drill the hole into the pipe with a

hole saw or drill. Do not torch cut the hole.

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 Annubar sensor 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

B, then subtract

/16-in. (1.6 mm).

4. Measure the distance from the end of the transferred length in Step 3 to the last sensing

hole, port A.

5. Compare the numbers obtained in Step 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.

can pass completely through the pipe. 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.

An alignment bar is needed during the welding of the heavy wall weldolets to the steam pipeline. The alignment bar can be ordered from Emerson

™

Process Management.

1. Weld the heavy wall weldolet to the packing gland assembly with a full penetration-groove weld.

a. Place the alignment bar through the packing gland and the weldolet. The weldolet

will also have a bearing sleeve in it and it should be near the radius end of the weldolet which will be the end welded to the pipe. Ensure the support plate is

attached to the packing gland before making the weld. b. Tack weld the weldolet to the packing gland. Remove the alignment bar. c. Weld the first pass. Recheck alignment with the alignment bar. Adjust alignment as

necessary. Do not allow the alignment bar to get too hot, as it will be difficult to

remove. Use it only briefly to check alignment between weld passes. d. Complete remaining weld passes, using alignment bar to verify alignment several

times during the process. Emerson Process Management recommends the weld

thickness is equal to the base metal thickness.

2. Weld the weldolet and packing gland assembly to the pipe.

a. Place alignment bar back into the pipe, slide the weldolet and packing gland

assembly down the alignment bar, and let it rest on the pipe. b. Ensure the 1

/8-in. (29 mm) holes in the support plate are perpendicular to the pipe centerline within ± 3° for horizontal lines and parallel to the pipe centerline within ± 3° for vertical lines. This will ensure the impact and static holes will be in line with the flow stream. See Figure 2-5 on page 10.

c. Tack weld the weldolet to the pipe. Check alignment. Remove the alignment bar

and weld the first pass. Emerson Process Management recommends using TIG welding for the first two passes as a minimum. Experience has shown that welding

about

/2 to 2/3 of the weld using GTAW (TIG) and then using other weld processes (GMAW, SMAW, FCAW) leads to lower chances of movement of the weldment during welding.

Installation

Reference Manual

00809-0100-4809, Rev DA

Note

It is very helpful to have two welders welding the assemblies to pipe, with one welder starting 180° from the other. This helps prevent movement of the fittings during the temperature changes associated with welding.

3. Weld the opposite side weldolet to the pipe.

Section 2: Installation

September 2015

d. Check the alignment after the first pass. Remove the alignment bar and weld the

next pass. Recheck alignment.

e. Continue applying weld passes and rechecking alignment until welding is complete.

The fillet welds will be approximately 1

/8-in. (29 mm).

a. Slide the alignment bar through mounting and hole in top side of pipe and place the

opposite-side support weldolet over the end of the alignment bar.

b. Visually center the opposite-side weldolet over the hole. Tack weld the weldolet,

using tack bars or an equivalent method.

c. Weld the first pass and check alignment using the alignment bar and continue

welding. Check alignment frequently during welding. Adjust weldolet as you are making tacks to keep aligned. Do not leave alignment bar in too long as it will heat up and make it very difficult to remove.

d. When welding is complete, the alignment bar should slide freely through the

packing into the opposite-side weldolet.

e. Weld opposite end cap to weldolet using a full penetration groove weld.

4. Perform required heat treatment.

5. Reinstall 585 Main Steam Annubar sensor after heat treating and ensure the flow arrow is pointing in the direction of flow.

Step 4: Insert the Annubar sensor

1. Place the packing into the packing gland with the two split rings (Garlock style 1303FEP) on the outside and the three Garlock Carbon/Graphite solid die-formed rings on the inside. Make sure the splits in the outer packing are 180° apart.

Note

The packing gland and support plate will be shipped fully assembled.

2. Slide the 585 Annubar sensor through the packing and install the locking rods, nuts, and lock washers. The dimension between the plates should be 11.0-in. (279 mm). See

Figure 2-38 on page 58. If there is visual access to the inside of the pipe, ensure that the

sensing holes are equally spaced from the inner diameter of the pipe.

3. Make the small adjustment (if necessary), then lock the 585 in place with the locking rods, nuts, and lock washers. When installed, the 585 will have a dimension of 29.6-in. (752 mm) from pipe OD to top of head.

4. The last thing to be done is to tighten the packing gland nuts to 25 to 30 ft-lbs. (34 to 41 N-m). See Figure 2-36.

a. Impulse piping must be non-insulated to reduce fluid temperature. b. Any threaded connections should be checked after the system reaches the intended

temperature because connections may come loose with contraction and expansion caused by temperature change.

 Outdoor installations may require insulation and heat tracing to prevent freezing.

 When impulse piping is longer than 6-f t. (1.8 m) the high and low impulse lines must be

positioned together to maintain equal temperature. They must be supported to prevent sagging and vibration.

 Impulse lines should be positioned in protected areas or against walls or ceilings. Use

appropriate pipe sealing compound rated for the service temperature on all threaded connections. Do not place the impulse piping near high temperature piping or equipment.

a. An instrument manifold is recommended for all installations. Manifolds allow an

operator to equalize the pressures prior to zeroing and isolates the process fluid from the transmitter.

b. Use only valves and fittings rated for the design pressure and temperature (in some

cases the primary instrument valve may be supplied by Emerson Process Management with the Annubar sensor).

c. Use a pipe thread sealant compound that is rated for use at the service temperature

and pressure for all valves and fittings. d. Verify that all connections are tight and that all instrument valves are fully closed. e. Verify that the sensor probe is properly oriented as per the submitted outline

drawings. f. The piping used to connect the sensor probe and transmitter must be rated for

continuous operation at the pipeline-designed pressure and temperature. A

minimum of one-half inch (

Do not connect the powered signal wiring to the test terminals. Power may damage the test diode in the test connection.

Plug and seal unused conduit connections on the electronics housing to avoid moisture accumulation in the terminal side of the housing. Excess moisture accumulation may damage the electronics. If the connections are not sealed, the electronics should be remote mounted with the electrical housing positioned downward for drainage. Wiring should be installed with a drip loop and the bottom of the drip loop should be lower then the conduit connections and the housing.

Inductive-based transient protectors, including the Rosemount 470 transient protector, can adversely affect the output of the Annubar sensor. If transient protection is desired, install the Transient Protection Terminal Block. Consult the factory for instructions.

3.3 Commissioning the Annubar sensor

1. Open first the equalizer valve(s) MEL and MEH or ME.

2. Close valves MH and ML.

3. Read the transmitter output. It should read within the range 3.98 mA to 4.02 mA. If the output is outside of this range, perform a zero trim procedure as described in transmitter manual (see Table 3-1 for transmitter manual document numbers).

“Calibrate out” line pressure effects

For applications with static pressures of 100 psi (6.9 bar) and higher, the DP sensor should be zeroed for line pressure effects. The “zero” calibration procedure is affected by static pressure and ambient temperature, but these effects can be minimized by zeroing the DP sensor at normal operating conditions.

The effect of static pressure is calibrated out by exposing the transmitter to the line pressure and performing a “zero” or wet calibration, as described below.

Although the line pressure effects are relatively small, they significantly affect the accuracy of the Annubar sensor when used with low flows.

Check for system leaks

Check the system for leaks after installation is complete. A leak in a differential pressure instrument system can produce a difference in pressure that is larger than the signal itself.

Before the system is filled and/or commissioned, it is a simple matter to use compressed air or another inert, compressed gas to check for leaks. The gas pressure must be below the maximum allowed, but at least equal to the normal operating pressure in order to reveal potential leaks. A typical pressure used is 100 psig (690 kPa).

Before pressurizing the system, check for leaks by doing the following:

1. Open equalizer valve(s) MEH, MEL, or ME to prevent over-pressuring the DP sensor on

2. Close valves PH, PL, MV, DVH, and DVL.

one side. Refer to Figure 3-4, Figure 3-5, and Figure 3-6 for valve designations.

5. Apply pressure at a convenient point on either the high or low side of the system. The DVH, DVL, or MV ports could be used.

6. Use a suitable leak detection solution and apply to all of the impulse piping, valves, manifold, and connections. A leak is indicated by a continuous stream of bubbles.

7. Repair any leaks in the system by first removing pressure from the system. Repeat Steps

1 - 6 as necessary until no leaks are detected.

8. Remove test pressure and re-install all appropriate plugs.

“Calibrate out” line pressure effects

Note

Do not begin this procedure until the system leak check has been completed on the impulse piping and all leaks have been fixed.

For applications 100 psi and higher, the DP sensor should be zeroed for line pressure effects. The “zero” calibration procedure is affected by static pressure and ambient temperature, but these effects can be minimized by zeroing the DP sensor at normal operating conditions.

The effect of static pressure is calibrated out by exposing the transmitter to the line pressure and performing a “zero” or wet calibration, as described below.

Although the line pressure effects are relatively small, they significantly affect the accuracy of the Annubar sensor when used with low flows.

3. If the resistance measured does not represent the proper temperature or no resistance is measured (i.e. Open circuit), the RTD is damaged and must be replaced.

Grounding check

1. Using an Ohm meter or a Multimeter, test for each wire of the RTD to the sheath for a resistance value. If the RTD is installed in the Annubar sensor, test to the instrument connections of Annubar sensor instead of the sheath of the RTD. All tests should measure an infinite resistance (i.e. Open circuit) between the RTD wires and the sheath.

Reference Manual

00809-0100-4809, Rev DA

2. If all tests verify an open circuit, the RTD is functioning properly.

3. If any tests confirm a shorted wire to the RTD sheath, the RTD is damaged and must be replaced.

4.3 Pak-Lok, Flange-Lok, and Flo-Tap maintenance

The Pak-Lok, Flange-Lok, and Flo-Tap models utilize a packing gland mechanism to sustain a seal on the process fluid. Periodically the packing rings need to be checked to ensure that they are continuing to seal properly.

 Check the packing gland for leaks. If a leak is present, check that the nuts are tightened

down on the packing studs. If the leak persists, then the packing rings should be replaced.

 If the process fluid goes through large degrees of temperature cycling, verify that the

packing is tightened down sufficiently and that the tip of the Annubar sensor is still secured against the opposite side pipe wall. A leak would indicate the packing has loosened. Also, excessive vibration of the Pak-Lok, Flange-lok, or Flo-tap model could indicate the tip of the sensor is no longer secured to the pipe wall. For the Pak-lok or Flange-lok models, re-tighten the nuts to ensure that the packing is sufficiently tightened and that the tip of the Annubar sensor is still secured against the opposite side pipe wall. For the Flo-tap models, tighten the drive nuts or rotate the crank clockwise until the sensor is secured against the opposite side pipe wall. Re-tighten the packing gland nuts to ensure that the packing is sufficiently tightened.

 If there is excessive vibration present in the Annubar sensor, immediate attention is

required as the sensor may no longer be secured against the opposite side pipe wall. This could result in the sensor bending, cracking, or breaking. For the Pak-lok or Flange-lok models, re-tighten the nuts to ensure that the packing is sufficiently tightened and that the tip of the Annubar sensor is still secured against the opposite side pipe wall. For the Flo-tap models, tighten the drive nuts or rotate the crank clockwise until the sensor is secured against the opposite side pipe wall. Re-tighten the packing gland nuts to ensure that the packing is sufficiently tightened. If excessive vibration is still present, contact an Emerson

 If the packing rings appear brittle, old, or compressed beyond further use, a new set of

rings should be ordered for replacement. Installation instructions can be found in

4.4 Gas entrapment

In certain liquid applications (i.e. – buried water lines) it may be necessary to mount the transmitter and Annubar sensor above the pipe. This can lead to gas entrapment in the impulse piping which causes erratic flow readings.

One way to combat this problem is to install Automatic Vent Packages (AVP) on the impulse lines. The vents will purge the gas periodically and keep the impulse lines clear. The key to the installation is installing the vents and impulse piping so that any gas travels up to the vents and away from the transmitter. Vents can usually be installed at any time. Contact your Emerson Process Management representative for more details.

4.5 Dirt accumulation

One inherent advantage of an Annubar primary element over devices such as orifice plates is the ability to function in flows carrying dirt and grease. However, under extreme cases, some of the sensing ports are completely obstructed or the outside shape is drastically changed by buildup.

Reference Manual

00809-0100-4809, Rev DA

There are two methods of cleaning the Annubar primary element to restore performance. Mechanical cleaning is the more certain method, but does require removal of the Annubar primary element. Purging is effective if the accumulation covers the sensing ports or blocks internal passages.

In applications where a large amount of foreign material exists, it may be necessary to perform a routine preventative maintenance by removing the Annubar primary element for cleaning. The outer surfaces should be cleaned with a soft wire brush. The internal passages should be cleaned with compressed air. If necessary, a solvent for dissolving foreign material may be appropriate.

Purging with an external fluid source under a higher pressure is an effective means of retaining clear pressure pathways in the Annubar primary element.

The following precautions should be taken:

1. The purging fluid must be compatible with the process fluid and shouldn't cause other problems such as contamination.

2. The purging fluid should be preheated or pre-cooled if the temperature difference of the fluid and the process exceeds 150 °F (66 °C).

3. The differential pressure transmitter or meter should be isolated from the purge fluid to prevent over-ranging.

4. Continuous purging is not recommended.

The length of time between purges, or the cycle time, as well as the length and volume of the purge cycle must be determined experimentally. Some guidelines established as a starting point for experimentation are as follows:

1. Supply pressure of at least 60 PSIG (415 kPa-g) and not exceeding 115 PSIG (795 kPa).

2. Purge air flow rate of at least 40 SCFM (68 Nm

3. Purge duration of at least 60 seconds.

/h) when flowing at 60 PSIG (415 kPa).

Operation and Maintenance

Reference Manual

00809-0100-4809, Rev DA

4. Purge with dry air (less than 5% moisture by weight).

Section 4: Operation and Maintenance

September 2015

5. Stainless steel purge tubing should have a minimum of least 0.035-in. (0.89 mm) wall thickness. Care must be taken to protect the secondary instrumentation from high pressures and temperatures when purging an Annubar primary element. Ear protection is also recommended for all personnel in the vicinity of the system being purged. See figure for sample set-up.

4.6 Main steam line Annubar sensor maintenance

Due to the extreme conditions that the Rosemount® 585 Main Steam Line Annubar Flowmeters come into contact with, it should be removed and inspected annually to check for wear. Emerson Process Management recommends a visual inspection and a Dye Penetrant; examine to identify any cracks or wear on the Annubar sensor. After the Annubar sensor is inspected, it is recommended to replace the packing rings to ensure a proper seal. Tab l e 4 -1 shows the replacement part numbers for the packing rings and other spare parts.
