SYSTEM DESCRIPTION Rosemount Series 8700 Magnetic Flowmeter Systems measure

volumetric flow rate by detecting the velocity of a conductive liquid that

passes through a magnetic field. Magnetic Flowmeter Systems consist

of a flowtube and a transmitter.

There are three Rosemount magnetic flowmeter flowtubes:

• Flanged Model 8705

• Flanged High-Signal Model 8707

• Wafer-Style Model 8711

There are three Rosemount magnetic flowmeter transmitters:

• Model 8712C/U/H

• Model 8732C

• Model 8742C

The flowtube is installed in-line with process piping — either vertically

or horizontally. Coils located on opposite sides of the flowtube create the

necessary magnetic field. A conductive liquid moving through the

magnetic field generates a voltage that is detected by two electrodes.

The transmitter drives the coils to generate a magnetic field and

electronically conditions the voltage detected by the electrodes. The

transmitter then produces output signals proportional to the

liquid velocity.

SAFETY MESSAGES Procedures and instructions in this manual may require special

precautions to ensure the safety of the personnel performing the

operations. Refer to the safety messages listed at the beginning of each

section before performing any operations.

SAFETY MESSAGES This section covers the steps required to physically install the flowtube.

Instructions and procedures in this section may require special

precautions to ensure the safety of the personnel performing the

operations. Please refer to the following safety messages before

performing any operation in this section.

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

Installation and servicing instructions are for use by qualified personnel only.

Performing any servicing other than that contained in this manual may

result in death or serious injury. Do not perform any servicing other than

that contained in the operating instructions, unless qualified.

The flowtube liner is vulnerable to handling damage. Never place anything through

the flowtube for the purpose of lifting or gaining leverage. Liner damage can render

the flowtube useless.

To avoid possible damage to the flowtube liner ends, do not use metallic or

spiral-wound gaskets. If frequent removal is anticipated, take precautions to protect the

liner ends. Short spool pieces attached to the flowtube ends are often used for

protection.

Correct flange bolt tightening is crucial for proper flowtube operation and life. All bolts

must be tightened in the proper sequence to the specified torque limits. Failure to

observe these instructions could result in severe damage to the flowtube lining and

possible flowtube replacement.

STEP 1: HANDLING Handle all parts carefully to prevent damage. Whenever possible,

transport the system to the installation site in the original shipping

containers. Teflon®-lined flowtubes are shipped with end covers that

protect it from both mechanical damage and normal unrestrained

distortion. Remove the end covers just before installation.

Flanged 6- through 36-inch flowtubes come with a lifting lug on each

flange. The lifting lugs make the flowtube easier to handle when it is

transported and lowered into place at the installation site. Flanged ½-

to 4-inch flowtubes do not have lugs. They must be supported with a

lifting sling on either side of the housing.

Figure 2-1 shows flowtubes correctly supported for handling and

installation. Notice the plywood end pieces are still in place to protect

the flowtube liner during transportation.

FIGURE 2-1. Flowtube Support for

Handling and Installation

STEP 2: MOUNTING Physical mounting of a flowtube is similar to installing a typical section

of pipe. Conventional tools, equipment, and accessories (bolts, gaskets,

and grounding hardware) are required.

Calibration Rosemount flowtubes are wet calibrated at the factory. They do not

need further calibration during installation.

See Safety Messages on page 2-1 for complete warning information.

Installation

Upstream/

Downstream Piping

To ensure specification accuracy over widely varying process conditions,

install the flowtube a minimum of five straight pipe diameters

upstream and two pipe diameters downstream from the electrode plane

(see Figure 2-2).

FIGURE 2-2. Upstream and

Downstream Straight Pipe Diameters

Flowtube Orientation The flowtube should be installed in a position that ensures the flowtube

remains full during operation. Horizontal or inclined positions are

preferred. Figures 2-3, 2-4, and 2-5 show the proper flowtube orientation

for the most common installations.

The following orientations ensure that the electrodes are in the

optimum plane to minimize the effects of entrapped gas. Further

information on electrode orientation can be found in Appendix A.

As illustrated in Figures 2-4B and 2-5B, avoid downward flows where back

pressure does not ensure that the flowtube remains full at all times.

Installation

Flow Direction The flowtube should be mounted so that the FORWARD end of the flow

arrow, shown on the flowtube identification tag, points in the direction

of flow through the tube (see Figure 2-6). In this mounting

configuration, the conduit ports point upstream.

STEP 3: INSTALLATION OF

MODEL 8705 AND MODEL

8707 HIGH-SIGNAL

The following drawings should be used as a guide in the installation of

the Model 8705 and Model 8707 High-Signal Flowtubes. Refer to page

2-8 for installation of the Model 8711 Flowtube.

Gaskets The flowtube requires a gasket at each of its connections to adjacent devices

or piping. The gasket material selected must be compatible with the process

fluid and operating conditions. Metallic or spiral-wound gaskets can

damage the liner. If the gaskets will be removed frequently, protect the

liner ends.

A gasket is required on each side of the grounding ring, as shown in

Figure 2-7. All other applications (including lining protector and

grounding electrode) require only one gasket on each end connection, as

shown in Figure 2-8.

STEP 3: INSTALLATION OF

MODEL 8711

The following section should be used as a guide in the installation of the

Model 8711 Flowtube.

Gaskets The flowtube requires a gasket at each of its connections to adjacent devices

or piping. The gasket material selected must be compatible with the process

fluid and operating conditions. Metallic or spiral-wound gaskets can

damage the liner. If the gaskets will be removed frequently, protect the

liner ends. If grounding rings are used, a gasket is required on each

side of the grounding ring.

Alignment and Bolting 1. On 1½ - through 8-inch (40 through 200 mm) line sizes, place

centering rings over each end of the flowtube. The smaller line

sizes, 0.15- through 1-inch (4 through 25 mm), do not require

centering rings.

2. Insert studs for the bottom side of the flowtube between the pipe

flanges. Stud specifications are listed in Table 2-2 Using carbon

steel bolts on smaller line sizes, 0.15- through 1-inch (4

through 25 mm), rather than the required stainless steel

bolts, will degrade performance.

TABLE 2-2. Stud Specifications

3. Place the flowtube between the flanges. Make sure that the

centering rings are properly placed in the studs. The studs should

be aligned with the markings on the rings that correspond to the

flange you are using.

4. Insert the remaining studs, washers, and nuts.

5. Tighten to the torque specifications shown in Table 2-1 Do not

overtighten the bolts or the liner may be damaged.

NOTE

On the 4- and 6-inch PN 10–16, insert the flowtube with rings first and then

insert the studs. The slots on this ring scenario are located on the inside of

the ring.

STEP 4: GROUNDING Grounding the flowtube is one of the most important details of flowtube

installation. Proper grounding ensures that only the voltage induced in

the magnetic field of the flowtube is measured. Use Table 2-4 to

determine which grounding option to follow for proper installation.

Attached grounding rings should be grounded equivalently to

non-attached grounding rings.

NOTE

Consult factory for installations requiring cathodic protection or situations

where there are high currents or high potential in the process.

The flowtube case should always be grounded in accordance with

national and local electrical codes. Failure to do so may impair the

protection provided by the equipment. The most effective grounding

method is direct connection to earth ground with minimal impedance.

The Internal Ground Connection (Protective Ground Connection)

located in side the junction box is the Internal Ground Connection

screw. This screw is identified by the ground symbol:

Installation

STEP 5: WIRING The conduit connections needed for installation depend on transmitter

location. A conduit run between the flowtube and transmitter is not

required if the transmitter is integrally mounted on the flowtube.

Conduit Ports

and Connections

Both the flowtube and transmitter junction boxes have ports for ¾-inch

NPT conduit connections. These connections should be made in

accordance with local or plant electrical codes. Unused ports should be

sealed with metal plugs. Housing damage will result if metal plugs

are overtightened.

Flanged and wafer flowtubes have two conduit ports as shown in

Figures 1, 2, 3, and 1. Either one may be used for both the coil drive and

electrode cables. Use the stainless steel plug that is provided to seal the

unused conduit port.

Series 8700 Flowtubes use a pulsed-dc signal generated by Model

8712C/U/H, Model 8732C, or Model 8742C Magnetic Flowmeter

Transmitter. Connect the Model 8712H High-Signal Magnetic

Flowmeter Transmitter only to the Model 8707 High-Signal Flowtube.

A single dedicated conduit run for the coil drive and electrode cables is

needed between a flowtube and a remote transmitter. Bundled cables in

a single conduit are likely to create interference and noise problems in

your system. Use one set of cables per conduit run. See Figure 2-15 for

proper conduit installation diagram and Table 2-5 for

recommended cable.

Use wire rated for the proper temperature application. For connections

in ambient temperatures above 140 °F (60 °C), use a wire rated for

176 °F (80 °C). For ambients greater than 176 °F (80 °C), use a wire

rated for 230 °F (110 °C).

This is a pulsed dc magnetic

flowmeter. Do not connect ac

power to the flowtube or to

terminals 1 and 2 of the

transmitter, or replacement of the

electronics board will be necessary.

Installation

Cable Preparation Prepare the flowtube ends of the coil drive and electrode cables, as

shown in Figure 2-16.

NOTE

The maximum length for unshielded wire in the wiring compartment is ½-inch.

Correct cable preparation is important for a successful installation. The

STEP 6: PROCESS LEAK

PROTECTION

(MODEL 8705 AND MODEL

8707 HIGH-SIGNAL ONLY)

The Model 8705 and Model 8707 High-Signal Flowtube housing is

fabricated from carbon steel to perform two separate functions. First, it

provides shielding for the flowtube magnetics so that external

disturbances cannot interfere with the magnetic field and thus affect

the flow measurement. Second, it provides the physical protection to

the coils and other internal components from contamination and

physical damage that might occur in an industrial environment. The

housing is completely welded and gasket-free.

The three housing configurations are identified by the W0, W1, or W3

in the model number option code when ordering. Below are brief

descriptions of each housing configuration, which are followed by a

more detailed overview.

•Code W0 — sealed, welded coil housing (standard configuration)

•Code W1 — sealed, welded coil housing with a relief valve

capable of venting fugitive emissions to a safe location (additional

plumbing from the flowtube to a safe area, installed by the user, is

required to vent properly)

•Code W3 — sealed, welded coil housing with separate electrode

compartments capable of venting fugitive emissions (additional

plumbing from the flowtube to a safe area, installed by the user, is

required to vent properly)

Standard Housing

Configuration

The standard housing configuration is identified by a code W0 in the

model number. This configuration does not provide separate electrode

compartments with external electrode access. In the event of a process

leak, these models will not protect the coils or other sensitive areas

around the flowtube from exposure to the pressure fluid.

8705-1002A05D

Rosemount Series 8700 Magnetic Flowmeter Flowtube

2-20

Relief Valves The first optional configuration, identified by the W1 in the model

number option code, uses a completely welded coil housing. This

configuration does not provide separate electrode compartments with

external electrode access. This optional housing configuration provides

a relief valve in the housing to prevent possible overpressuring caused

by damage to the lining or other situations that might allow process

pressure to enter the housing. The relief valve will vent when the

pressure inside the flowtube housing exceeds 5 psi. Additional piping

(provided by the user) may be connected to this relief valve to drain any

process leakage to safe containment (see Figure 2-21).

Installation

Process Leak Containment The second optional configuration, identified as option code W3 in the

model number, divides the coil housing into three compartments: one

for each electrode and one for the coils. Should a damaged liner or

electrode fault process fluid to migrate behind the electrode seals, the

fluid is contained in the electrode compartment. The sealed electrode

compartment prevents the process fluid from entering the coil

compartment where it would damage the coils and other

internal components.

The electrode compartments are designed to contain the process fluid at

full line pressure. An o-ring sealed cover provides access to each of the

electrode compartments from outside the flowtube; drainports are

provided in each cover for the removal of fluid.

NOTE

The electrode compartment could contain full line pressure and it must

be depressurized before the cover is removed.

FIGURE 2-22. Housing Configuration

If necessary, capture any process fluid leakage, connect the appropriate

piping to the drainports, and provide for proper disposal (see Figure

2-22).

STEP 7: START-UP

AND OPERATION

Start-up and operation is dependent upon the transmitter selected to

complement the flowtube. For transmitter start-up information, refer to

the Model 8712C/U/H manual (document 00809-0100-4729), the Model

8732C manual (document 00809-0100-4725), or the Model 8742C

manual (document 00809-0100-4793).

Flowtube

Calibration Number

A unique flowtube calibration number, imprinted on the flowtube tag,

enables any flowtube to be used with any Rosemount transmitter

without further calibration. Rosemount flow lab tests determine

individual flowtube output characteristics. The characteristics are

identified by a 16-digit calibration number.

The 16-digit calibration number can be programmed into the Model

8712C/U/H or Model 8732C transmitter using the Local Operator

Interface (LOI) or the Model 275 HART® Communicator. Refer to the

appropriate transmitter product manual for complete instructions. In a

FOUNDATION™ fieldbus environment, the Model 8742C can be

configured using the DeltaV™ configuration tool or another

FOUNDATION fieldbus configuration device.

The calibration number is more than a correction factor, or K- factor, for

the flowtube. The first five digits represent the low frequency gain. The

ninth through thirteenth digits represent the high frequency gain. Both

numbers are normalized from an ideal number of 10000. Standard

configurations use the low frequency gain, but in noisy applications it

may be worthwhile to switch to the higher frequency. An additional

transmitter procedure, called Auto Zero, is required to perform at the

higher coil drive frequency. The full procedure can be found in the

appropriate transmitter manual. The seventh and eigth digits

represent the zero offset at both frequencies where the nominal value

is 50. Empty pipe functionality is a transmitter feature that is

controlled by the flowtube calibration number. To turn off this feature,

change the fourteenth digit to the number 7.

Quick Start-up To initiate a basic transmitter start-up, only four parameters are required:

• Tube calibration number

•Tube size

•Units

• Analog output range (URV)

Refer to the Model 8712C/U/H, Model 8732C, or Model 8742C product

manuals for complete transmitter start-up instructions.

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.

INDEPENDENT

FLOWTUBE AND

TRANSMITTER

REPLACEMENT

Rosemount flow lab tests determine individual flowtube characteristics

and account for them with the 16-digit calibration number. Flowtube

interchangability reduces the need for spare transmitters. It also

ensures factory-calibrated accuracy without additional calibration

procedures or equipment. The unique calibration number is loaded into

the transmitters, enabling the interface of a Rosemount flowtube to

communicate with a Rosemount transmitter. A description of the

flowtube calibration number is included on page 2-22.

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

Installation and servicing instructions are for use by qualified personnel only.

Performing any servicing other than that contained in this manual may result in death

or serious injury. Do not perform any servicing other than that contained in the

operating instructions, unless qualified.

Mishandling products exposed to a hazardous substance may result in death or

serious injury. If the product being returned was exposed to a hazardous substance

as defined by OSHA, a copy of the required Material Safety Data Sheet (MSDS) for

each hazardous substance identified must be included with the returned goods.

FLOWTUBE

TROUBLESHOOTING

The Model 8712C/U/H, Model 8732C, or Model 8742C Magnetic

Flowmeter Transmitters perform self diagnostics on the entire

magnetic flowmeter system: the transmitter, the flowtube, and the

interconnecting wiring. While most of the diagnostics are related

to the transmitter microprocessor, some tests diagnose specific

flowtube problems.

NOTE

Before performing any of the flowtube tests, cut off power and

disconnect all connections inside the flowtube junction box.

If a problem with the flowtube is identified, the following chart can

assist in troubleshooting the flowtube.

Take all readings from inside the junction box with a multimeter.

Readings taken at the transmitter terminals may provide incorrect or

inconclusive information and should be avoided.

A flowtube circuit diagram is shown in Figure 3-1.

AField-Removable Electrodes

SAFETY MESSAGES Instructions and procedures in this section may require special

precautions to ensure the safety of the personnel performing

the operations.

The field-removable electrode option allows the user to remove the

electrode assembly with the flowtube still mounted in the line.

Frequently, this option will be used for cleaning the electrode head

when coating is of concern.

The flowtube should be drained of any process fluid prior to disassembly of

the electrodes. To avoid personal injury, care should be taken when

handling electrodes that have been in contact with corrosive process fluids.

Take care to avoid rotating the electrode when removing it to avoid

damage to the o-ring. Some resistance may be experienced due to the

tight o-ring fit.

REMOVE THE

ELECTRODE ASSEMBLY

Use the following procedure to remove the electrode assembly

from the flowtube.

1. Drain the flowtube of any process fluid prior to disassembly

of the electrodes.

2. Remove the screws that secure the electrode cover.

3. Remove the electrode cover and o-ring. It is generally

recommended that new o-rings be installed on the electrode and

the electrode cover during reassembly.

4. Remove the electrode lead screw that secures the signal wire to

the electrode.

5. Remove the electrode retaining nut.

6. Take the electrode from the electrode housing by pulling it

straight out, with firm pressure, along the axis of the electrode.

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

Installation and servicing instructions are for use by qualified personnel only.

Performing any servicing other than that contained in this manual may

result in death or serious injury. Do not perform any servicing other than

that contained in the operating instructions.

Rosemount Series 8700 Magnetic Flowmeter Flowtube

REPLACE THE

ELECTRODE ASSEMBLY

Use the following procedure to replace the electrode assembly

into the flowtube.

1. Lubricate the o-ring.

2. Install the o-ring on the electrode.

3. Insert the electrode into the electrode housing. Push straight in

until the electrode is seated. Avoid rotating the electrode or the

electrode housing as this could result in leakage.

4. Secure the electrode into the housing with the retaining nut and

lock washer. Tighten the retaining nut to 15 in/oz of torque.

Failure to tighten the fasteners can cause loss of liquid tight seal

and result in damage to the unit.

5. Secure the signal wire to the electrode with the electrode

lead screw.

6. Install the o-ring into the electrode cover.

7. Secure the electrode cover to the flowtube with the screws.
