RECEIVING

AND INSPECTION

RETURNING THE PRODUCT

CONSIDERATIONS

Limitations

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.

To expedite the return process, call the Rosemount National Response Center toll-free at 800-654-7768. This center, available 24 hours a day, will assist you with any needed information or materials.

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 substances, must be included with the returned materials.

Information in this manual applies to circular pipes only. Consult Rosemount Customer Central for instructions regarding use in square or rectangular ducts.

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.

3° max.

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.

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 threeor 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.

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.

	MODEL 3051/2024/3001/3095
	Flange Adapter
	O-ring
	Unique O-ring
	Grooves
	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.

(1)Quick troubleshooting check: There must be at least 11.0 V DC across the Model 3095MFA Mass ProBar electronics terminals.

Guidelines

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).

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).

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.

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.

Straight Run

Requirements

Use the following to aid in determining the straight run requirements

NOTE

•For gas service, multiply values from Table 2-2 on page 2-7 by 1.5.

•If longer lengths of straight run are available, position the mounting such that 80% of the run is upstream and 20% is downstream.

•The information contained in this manual is applicable to circular pipes only. Consult the factory for instructions regarding use in square or rectangular ducts.

•Straightening vanes may be used to reduce the required straight run length.

•Row 5 in Table 2-2 is to be used if a “through type” valve will remain open. Row 6 in Table 2-2 applies to gate, globe, plug, and other throttling valves that are partially opened, as well as control valves.

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 2-6 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.

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.

2-9

Annubar Flowmeter Series

Reference Manual

00809-0100-4809, Rev AA

August 2002

•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.

Step 2: Determine the Proper Orientation

Please refer to “Mounting” on page 2-4 for straight run requirements and orientation information.

Step 3: Drill a Hole into the Pipe

Follow the steps below to drill the hole in the pipe.

1.Depressurize and drain the pipe.

2.From the previous steps, select the location to drill the hole.

3.Determine the diameter of the hole to be drilled according to the specifications in Table 2-3 and drill the hole. Do not torch cut the hole.

Note: Drill the hole 180 degrees from the first hole for opposite-side support models.

Drill the appropriate diameter hole through the pipe wall.

8900-8900_15A

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.

2.If opposite side support is being used, center the fitting for the opposite

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