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 model number,

serial number, and customer tag number. Report any damage to the carrier.

The center will ask for the following information:

• Product model

• Serial numbers

• The last process material to which the product was exposed

The center will provide

• A Return Material Authorization (RMA) number

• Instructions and procedures that are necessary to return goods that

were exposed to hazardous substances

NOTE

If a hazardous substance is identified, a Material Safety Data Sheet (MSDS),

required by law to be available to people exposed to specific hazardous

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.

Annubar Flowmeter Series

The flowmeter can be installation with a maximum misalignment of 3 degrees

(see Figure 1-1). Misalignment beyond 3 degrees will cause flow

measurement errors.

Figure 1-1. Permissible

Misalignment

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.

Access Requirements

Consider the need to access the flowmeter when choosing an installation

location and orientation.

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.

NOTE

Rotating the housing more than 180 degrees will damage the sensor module

and void the warranty.

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 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.

Exterior

The integral span and zero push-buttons are located under the

certifications plate on the top of the ProBar. The plate will be blank if no

certifications are ordered.

Cover Installations

Always install the electronics housing covers metal-to-metal to ensure a

proper seal.

Figure 1-2. Electronics Housing

Process Considerations The process connections on the transmitter flange are 1/4–18 NPT. Flange

adapter unions with 1/2–14 NPT connections are available as options. These

are Class 2 threads; use the plant-approved lubricant or sealant when making

the process connections. The process connections on the transmitter flange

are on 21/8–in. (54 mm) centers to allow direct mounting to a three- or

five-valve manifold. By rotating one or both of the flange adapters, connection

centers of 2–, 21/8–, or 21/4–in. (51, 54, or 57 mm) may be obtained.

Annubar Flowmeter Series

Failure to install proper flange adapter O-rings can cause process leaks,

which can result in death or serious injury. There are two styles of Rosemount

flange adapters, each requiring a unique O-ring, as shown below. Each flange

adapter is distinguished by its unique groove.

Use only the O-ring designed to seal with the corresponding flange adapter.

Refer to the factory for the correct part numbers of the flange adapters and

O-rings designed for the flowmeter.

Teflon ® (PTFE) O-rings tend to cold flow when compressed, which aids in

their sealing capabilities. Whenever flanges or adapters are removed, visually

inspect the Teflon (PTFE) O-rings. Replace them if there are any signs of

damage. If the O-rings are replaced, the flange bolts may need to be

retorqued after installation to compensate for cold flow.

Electrical The signal terminals are located in a compartment of the electronics housing.

Connections for the Model 275 HART Communicator are located below the

signal terminals. The Model 272 Field Calibrator can be connected at the

signal terminals to provide temporary power to the electronics for calibration

or diagnostic purposes. Otherwise, the calibrator may be attached to the test

connections on the terminal block of the electronics for indication purposes.

Power Supply

The dc power supply should provide power with less than 2% ripple. The total

resistance load is the sum of the resistance of the signal leads and the load

resistance of the controller, indicator, and related pieces. Note that the

resistance of intrinsic safety barriers, if used, must be included.

NOTE

A loop resistance between 250-1100 ohms is required to communicate with a

personal computer. With 250 ohms of loop resistance, a power supply voltage

of at least 16.5 V dc is required.(1)

If a single power supply is used to power more than one Model 3095MFA

Mass ProBar, the power supply used, and circuitry common to the Mass

ProBars, should not have more than 20 ohms of impedance at 1200 Hz.

MOUNTING

Tools and Supplies Tools required include the following:

• Open end or combination wrenches (spanners) to fit the pipe fittings

and bolts: 9/16-in., 5/8-in., 7/8-in.

• Adjustable wrench: 15-in. (1½-in. jaw).

• Nut driver: 3/8-in. for vent/drain valves (or 3/8-in. wrench).

• Phillip’s screwdriver: #1.

• Standard screwdrivers: ¼-in., and 1/8-in. wide.

• Pipe wrench: 14-in.

• Wire cutters/strippers

•7/16-in. box wrench (required for the ferry head bolt design)

Supplies required include the following:

• ½-in. tubing (recommended) or ½-in. pipe to hook up the electronics to

the sensor probe. The length required depends upon the distance

between the electronics and the sensor.

• Fittings including (but not limited to)

• Two tube or pipe tees (for steam or high temperature liquid) and

• Six tube/pipe fittings (for tube)

• Pipe compound or Teflon (PTFE) tape (where local piping codes

allow).

Mounting Brackets Optional mounting brackets available with the instrument facilitate mounting to

a panel, wall, or 2-in. (50.8 mm) pipe. The bracket option for use with the

Coplanar flange is 316 SST with 316 SST bolts. See “Mounting” on page A-31

for bracket dimensions.

When installing the transmitter to one of the mounting brackets, torque the

bolts to 125 in-lb (169 n-m).

Bolt Installation

Guidelines

The following guidelines have been established to ensure a tight flange,

adapter, or manifold seal. Only use bolts supplied with the instrument or sold

by the factory.

The instrument is shipped with the coplanar flange installed with four 1.75-in.

(44.5 mm) flange bolts. The following bolts also are supplied to facilitate other

mounting configurations:

• Four 2.25-in. (57.2 mm) manifold/flange bolts for mounting the coplanar

flange on a three-valve manifold. In this configuration, the 1.75-in. (44.5

mm) bolts may be used to mount the flange adapters to the process

connection side of the manifold.

• (Optional) If flange adapters are ordered, four 2.88-in. (73.2 mm)

flange/adapter bolts for mounting the flange adapters to the coplanar

flange.

Stainless steel bolts supplied by Rosemount Inc. are coated with a lubricant to

ease installation. Carbon steel bolts do not require lubrication. Do not apply

additional lubricant when installing either type of bolt. Bolts supplied by

Rosemount Inc. are identified by the following head markings:

Figure 2-2. Coplanar Mounting

Instrument Manifolds Figure 2-3 on page 2-6 identifies the valves on a 5-valve and a 3-valve

manifold. Table 2-1 on page 2-6 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

electronics 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.

NOTE

Some recently-designed instrument manifolds have a single valve actuator,

but cannot perform all of the functions available on standard 5-valve units.

Check with the manufacturer to verify the functions that a particular manifold

can perform. In place of a manifold, individual valves may be arranged to

provide the necessary isolation and equalization functions.

Integral (Direct) Mount

NOTE

The integral mount flowmeter is usually shipped with the electronics bolted

directly to the sensor. If this is not so, contact Rosemount Customer Central

for more information.

Horizontal Pipes

Liquid or Steam Applications

Due to the possibility of air getting trapped in the probe, the sensor should

be located according to Figure 2-5 for liquid or steam applications. The

area between 0° and 30° angle should not be used unless full bleeding of

air from the probe is possible.

For liquid applications, mount the side drain/vent valve upward to allow the

gases to vent.

In steam applications, fill the lines with water to prevent the steam from

contacting the electronics. Condensate chambers are not required

because the volumetric displacement of the electronics is negligible.

Air and Gas Applications

Figure 2-5 illustrates the recommended location of the flowmeter in air or

gas applications. The sensor should be located on the upper half of the

pipe, at least 30° above the horizontal line.

For air and gas applications, mount the drain/vent valve downward to allow

liquid to drain.

Figure 2-5. Horizontal Pipe

Applications

Vertical Pipes

Liquid, Steam, Air, and Gas Applications

Figure 2-6 illustrates the recommended location of the flowmeter in liquid,

air, or gas applications.

The 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.

Annubar Flowmeter Series

Figure 2-6. Vertical Pipe

Applications

Remote Mount Instrument head connections differ between horizontal and vertical pipes.

Consult your specification head code number to confirm the proper pipe

orientation.

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 sensor probe is properly oriented for the intended type of

service: liquid, gas or steam (see Figures “Integral (Direct) Mount” on

page 2-8 and “Remote Mount” on page 2-9).

Impulse Piping

Impulse piping connects remote mounted electronics to the sensor.

Temperatures in excess of 250 °F (121 °C) at the electronics will damage

electronics components; impulse piping allows service flow temperatures to

decrease to a point where the electronics is no longer vulnerable.

The following restrictions and recommendations apply to impulse piping

location.

• Piping used to connect the sensor probe and electronics must be rated

for continuous operation at the pipeline-designed pressure and

temperature

• Impulse piping that runs horizontally must slope at least 1–in. per foot

(83mm/m).

• It must slope downwards (toward the electronics) for liquid and steam

applications.

• It must slope up (away from the electronics) for gas applications.

• For applications where the pipeline temperature is below 250 °F

(121 °C), the impulse piping should be as short as possible to minimize

flow temperature changes. Insulation may be required.

• For applications where pipeline temperature is above 250 °F (121 °C),

the impulse piping should have a minimum length of 1-ft. (0.30 m) for

every 100 °F (38 °C) over 250 °F (121 °C), which is the maximum

operating electronics temperature. Impulse piping must be uninsulated

to reduce fluid temperature. All threaded connections should be

checked after the system comes up to temperature, because

connections may be loosened by the expansion and contraction

caused by temperature changes.

• A minimum of 1/2-in. (12mm) outer diameter (OD) stainless steel tubing

with a wall thickness of at least 0.035-in. is recommended.

• Outdoor installations for liquid, saturated gas, or steam service may

require insulation and heat tracing to prevent freezing.

• For installations where the electronics are more than 6-ft. (1.8m) from

the sensor probe, 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.

Table 2-3. Drill Hole into Pipe

4. 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 a 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. Rewrap 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 Table 2-3, drill the hole into the

pipe with a hole saw or drill. Do not torch cut the hole.

5. Deburr the drilled hole(s) on the inside of the pipe.

Step 4: Weld the Mounting Hardware

1. Center the Pak-Lok body over the mounting hole, gap 1/16-in. (1.5 mm)

and place four 1/4-in. (6-mm) tack welds at 90° increments. Check

alignment of the Pak-Lok body both parallel and perpendicular to the

axis of flow. If alignment of mounting is within tolerances (see

Figure 2-11), finish weld per local codes. If alignment is outside of

specified tolerance make adjustments prior to finish weld.

opposite

side support over the opposite side hole, gap 1/16-in. (1.5 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 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.

NOTE

To avoid serious burns, allow the mounting hardware to cool

before continuing.

Step 5: Insert into the Pipe

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

installation.

1. Thread studs into the Pak-Lok body.

2. To ensure that 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.)

3. Rotating the flowmeter back and forth, insert the flowmeter into the

Pak-Lok body until the sensor tip contacts the pipe wall (or support

plug).

4. Remove the flowmeter.

5. Verify that the sensor tip made contact with the pipe wall by removing

the pipe and ensuring that some of the marker has been rubbed off.

For special-cleaned bars, look for wear marks on the tip. If the tip did

not touch the wall, verify pipe dimensions and the height of mounting

body from the OD of the pipe and re-insert.

6. Re-insert the flowmeter into the Pak-Lok body and install the first

packing ring on the sensor between the lock ring and the packing

follower. Do not damage the split packing rings.

7. Push the packing ring into the Pak-Lok body and against the weld

lock ring. Repeat this process for the two remaining rings, alternating

the location of the packing ring split by 180°.

• Place the included split-ring lock washer between each of the nuts and

the compression plate. Give each nut one half (1/2) turn in succession

until the split-ring lock washer is flat between the nut and the

compression plate. Inspect the unit for leakage; if any exists, tighten

the nuts in one-quarter (1/4) turn increments until there is no leakage.

NOTE

On sensor size (1), failure to use the split-ring lock washers, improper washer

orientation, or over-tightening the nuts may result in damage to the flowmeter.
