1.0 INTRODUCTION
1.1 General
1.1.1 Description
The ABB Instrumentation Model 10DX3111 Magnetic Flowmeter is a volumetric liquid flow rate de-
tector that uses as the process transducing method the characteristic of a conductive fluid to gener-
ate an induced voltage when flowing through a magnetic field. The amplitude of the voltage
produced is directly proportional to the flow rate of the metered fluid.
Being a completely obstructionless metering instrument, the ABB Instrumentation Model 10DX3111
Magnetic Flowmeter can be used to meter liquids without regard to heterogeneous consistency and
is as independent of the tendency to plug or foul as the pipeline in which it is mounted. An inher-
ent advantage of obstructionless construction is that pressure losses are reduced to levels occur-
ring in equivalent lengths of equal diameter pipeline. This reduces or conserves pressure source
requirements in new or existing hydraulic lines as compared to other metering methods. The com-
pact size of the meter results in a light-weight unit which requires no additional support other than
that used normally on pipe runs. Short laying lengths minimize the need for altering existing pipe
runs to accommodate metering. A basic construction of non-corrosive wetted parts and a variety
of meter lining materials permit metering of most corrosive and reactant fluids.
Factors such as fluid viscosity and density require no compensation and have no effect on the
measurement accuracy of the Magnetic Flowmeter. Metering limitations are confined to a mini-
mum threshold of electrical conductivity inherent to the fluid being metered. The degree of fluid
conductivity has no effect upon metering accuracy as long as it is greater than this minimum level.
Fluid temperature is limited only to the extent that it may affect fluid conductivity and, like fluid pres-
sure, to the extent that it can not exceed the meter material specification limits.
1.1.2 Construction
The ABB Instrumentation Model 10DX3111 Magnetic Flowmeter, as shown in Figure 1-1, Cut-Away
View, consists of a flanged, carbon steel pipe spool which serves as a meter body. A pair of
arched, oval magnet coils fit on opposite sides of the meter body inner surface. This permeable
metal pipe spool acts as a core or return path for the magnetic field generated by the coils.
The coils are potted within an epoxy-base compound. An insulating interior liner of NEOPRENE or
polyurethane is inserted and turned-out against the flange faces. Two cylindrical electrodes are
mounted diametrically opposed within the central portion of the meter body and are completely in-
sulated from the metal pipe. The end surfaces of the standard electrodes are virtually flush with
the inner surface of the insulating liner and come into contact with the fluid to be metered. Bullet
nosed electrodes are mounted in a similar way; however, these electrodes protrude slightly beyond
the inner surface of the liner. Standard or bullet nosed electrodes are available. The electrodes
are replaceable without removing the meter from the pipeline.
The meter is available in three versions: splashproof, accidental submergence and continuous sub-
mergence.

All outer surfaces of the standard meter, with the exception of flange faces, are sprayed with a rust
prohibitive paint. At special option, these surfaces may be treated with corrosion-resistant epoxy
paint.

METER CAPACITY (10m/sec)
Each 10DX3111 meter in sizes 30" through 78" is calibrated at the factory and the meter capacity
unique to the individual meter is indicated on a tag attached to the side of the meter body. See the
instructions for the converter in the Converter/Driver for details on programming the converter to
use this meter capacity. Note that this is truly a PROGRAMMABLE factor; do NOT follow con-
verter instructions for using a "constant meter factor".
The range requested by the customer is also marked on the tag attached to the meter.

2.0 INSTALLATION
2.1 Inspection
The Magnetic Flowmeter should be inspected before installation for indications of damage which
may have occurred during shipment. All damage claims should be reported to the shipping agent
involved for equipment shipped F.O.B. job site before installation or operation is attempted. If dam-
age is such that faulty operation is likely to result, it should be brought to the attention of the ABB
Instrumentation Service Department.
2.2 Uncrating & Handling
All ABB Instrumentation Magnetic Flowmeters are shipped with the flanges protected. Lift the Mag-
netic Flowmeter using a winch or block and tackle attached to the lifting lugs as shown in Figure 2-
1. (Meter sizes 54" and smaller have two lifting lugs. Sizes 60" and larger have four lifting
lugs.)The rig must be able to support weights as shown in the Specifications sub-section of the IN-
TRODUCTION and must be long enough to produce an angle of 45°or greater between the sling
line and the metal pipe axis.
FIGURE 2-1. PROPER HOISTING TECHNIQUE
10DX3111 INSTRUCTION MANUAL

The exposed liner material on the meter flange faces is susceptible to damage if mishandled. Do
not walk the meter on its ends. Always use the protective end covers when the meter is trans-
ported.
CAUTION
Never allow any support for the Magnetic Flowmeter to bear upon the
inner surface of the meter pipe section inasmuch as the liner may
become damaged. Do not lift the meter by the electrode bosses.
The protective wooden flange covers or paper guard caps must be removed for inspection and be-
fore mounting in the pipeline.

2.3 Location
Stray electromagnetic and electrostatic fields normally encountered in most industrial areas will
have no effect upon the operating characteristics of the ABB Instrumentation Magnetic Flowmeter.
It is recommended, however, that the meter not be installed within the immediate proximity of
heavy induction equipment.
In-the-line meter maintenance is minimized with this instrument. Further, as no operating adjust-
ments are required in the ABB Instrumentation Magnetic Flowmeter, servicing accessibility is of
secondary importance unless greasy sludges or liquids bearing insulating materials which tend to
coat pipe walls are to be metered. However, sufficient access room should be allocated to facili-
tate electrical interconnection and permit field replacement of electrodes should the need arise.
The installation site must be provided with a convenient source of power as specified with the Con-
verter/Driver. The line should have a disconnect switch and a suitable fuse or circuit breaker as
given on the interconnection diagram of the receiving instrument instruction bulletin. Further, if the
pipeline is not in itself a good ground, a suitable earth ground must be made available in proximity
to the installation site.

2.4 Mounting
2.4.1 Orientation
The ABB Instrumentation Model 10DX3111 Magnetic Flowmeter may be oriented at any angle in
the pipeline. However, precautions must be taken to assure that the metering tube is filled at all
times during measurement. A vertical installation of the metering tube in a pipeline carrying fluid
upwards assures a filled hydraulic line under low flow rate conditions and also minimizes uneven
wear on the meter lining by abrasive grit. Horizontal installations should be made in a lower seg-
ment of the pipeline to assure a filled meter condition. Further, for horizontal or sloping installa-
tions, the meter should be placed so that the connection bosses are on top to align the meter
electrodes in a lateral plane. Positioning the meter in this way eliminates the possibility of en-
trained air acting as an electrode insulator.
The Magnetic Flowmeter may be mounted in the pipeline without regard to flow direction. If greasy
sludges or insulating materials which tend to coat pipe walls are to be metered, it is recommended
that in addition to standard block valves and bypass line, a clean-out tee be installed as shown in
Figure 2-2 to facilitate meter cleaning without removal or interruption of the process.

this instruction bulletin.

2.4.2 Pipe Connections
Standard meter piping connections are made by means of flanges that conform to ANSI standards
in outside diameter and bolt circle. The bearing surfaces of the flanges are insulated with the me-
ter pipe liner. Outline and mounting dimensions for meters specified for continuously submerged
applications are given in Figures 2-3 and 2-4. Figures 2-5 and 2-6 provide outline and mounting di-
mensions for meters used in accidental submergence applications.
It is generally recommended that two pipe spools be installed, one on each end fitting of the Mag-
netic Flowmeter, while it is out of the pipeline in order to minimize the possibility of damage to the
meter pipe and flange liner during mounting.
A pair of the proper gaskets to suit the particular lining option of the meter supplied is included
within the installation kit which accompanies the Magnetic Flowmeter. Before connections are
made, the bearing surfaces of NEOPRENE- or polyurethane-lined meter flanges, their NEOPRENE
gaskets and adjacent pipeline flanges should be thoroughly dusted with talc gasket powder. This is
done to prevent possible damage to the meter lining or gaskets, should the meter be removed from
the line.
If the Magnetic Flowmeter is to be mounted in a non-conductive pipeline or a metal pipeline with an
insulating liner, the user must provide a pair of suitable gaskets between the customer-supplied an-
nular meter grounding rings (discussed under Grounding Procedure, Case 2, below) and the adja-
cent pipeline flange surfaces.
The standard coarse thread flange bolts supplied by the user must be well lubricated and tightened
in even increments around the flange surface. Bolt torque should be limited to that which will pro-
duce a positive seal for the application.
