Section 1
IZMSG Components
The Anderson Instrument IZMSG Compact Flowmeter is a precision
instrument for sanitary volumetric measurement of electrically conductive
fluids. The IZMSG flowmeter is designed to function within a wide range of
operating conditions. It uses a measuring principle that eliminates moving
parts or probes in the fluid flow which would contribute to fluid pressure
losses.
The IZMSG flowmeter is engineered to provide maintenance-free operation.
The non-obstructive design of the flow tube permits CIP (clean in place) and
air blow or purge operation without damage to the flowmeter. See
Appendix B, Theory of Operation, for an explanation of the measuring
principle used in the IZMSG flowmeter.
The instructions in this document address the preparation, installation, and
start-up of the IZMSG flowmeter meter body and converter as separate units.
Information is provided on placing and mounting the meter body and
converter, installing and connecting cabling, making electrical connections,
commissioning the flowmeter, and conducting the hydraulic zero adjustment.
Unpacking
As you remove the system components from their boxes, inspect each piece. If
anything looks damaged, or is missing, contact the shipping agent or Anderson
Instrument Company, as appropriate.

Figure 1-1. Meter Body Components
Meter body and converter are shipped as matched pairs with identical serial
numbers. As you unpack the components, pair up each meter body with its
matching converter and keep the matched pairs together during installation.
Meter Body
The meter body is diagramed in Figure 1-1. The meter body housing has the
flow tube through the center and the field terminal box on top. A pair of
connection adapters is attached to each end of the flow tube with a
connection gasket and held in place by bolts.
The meter body incorporates two electromagnetic coils and a PFA-lined flow tube
in a stainless steel housing. Two electrodes are located inside the flow tube. The
electrodes are centrally located in the flow tube and are diametrically opposed. The
electrodes do not protrude into the flow tube and therefore will not disturb the fluid
flow.
Converter
The microprocessor-based converter changes electrical signals from the meter body
into flow rate and total data (see Figure 1-2). A coil drive circuit in the converter
provides a switched and regulated constant coil current that excites a magnetic field

Figure 1-2. IZMSG Compact Converter
(side and front with display/keypad option)
within the flow tube. The signal induced at the electrodes is amplified, digitized, and
processed by the converter. The converter produces two separate frequency
outputs and a 4 to 20mA analog output that are proportional to the flow rate.
Connection Cables
Anderson Instrument provides two shielded connection cables to connect the
meter body with the converter. The customer must provide the AC supply
voltage wiring and signal output cabling to peripheral devices. See Section 3,
Making Electrical Connections, for drawings and additional information about
the cables.
The Electrode Signal Cable is a 3-conductor cable with a shield wire. It is used
to connect the electrodes in the meter body to the converter. The Coil Drive
Cable is a 2-conductor cable with a shield wire. It is used to connect the coils
in the meter body to the converter. Ferrules are attached on the ends of the
wires of each cable to ensure proper connections to the terminals in the meter
body and the converter.
Note: The standard connection cable length is 25 feet. Longer
connection cable length can be ordered from Anderson
Instrument. Never splice cables together. If a connection
cable shorter than 25 feet is required, it must be trimmed in
the field (see Section 3, Making Electrical Connections).

Installing the Meter Body and Converter
Meter Body
The meter body is shipped ready for installation in a matched pair with a
converter. Verify that the converter serial number matches the meter body
serial number.
The stainless steel connection adapters are factory assembled to the inlet and
outlet sides of the meter body flow tube by bolts (see Figure 2-1).
The connection adapters must always remain assembled to the meter body
and should be removed for inspection purposes only. The adapters protect
the ends of the PFA liner. The proper fit and seal is maintained between the
connection adapters and the flow tube by o-ring connection gaskets.

2-2 IZMSG Compact Electromagnetic Flowmeter
AIC 2071
Caution
Never install the meter body without a
connection seal between the meter body flow tube
and the connection adapter. Never substitute any
other style of seal for the factory-supplied seals.
Location
The meter body provides Anderson measuring results when installed in
either a vertical or horizontal pipe section. Select a location where the meter
body will be completely filled with product. There must be a rise in the
piping at the outlet side of the meter body. Avoid the presence of air, either
bulk or entrained, from entering the product as it passes through the flow
tube.
In a vertical pipe section, install the meter body in the upward direction of
flow. In a horizontal pipe section, install the meter body at the lowest
possible point of the piping system and position the meter body with the axis
of the electrodes horizontal to the ground. This position will reduce sediment
deposits and/or air bubbles on the electrode surface.
Precautions that must be followed when selecting a location for the meter
body include:
P Do not install the meter body where the ambient temperature
exceeds 130°F.
P Avoid installing the meter body next to equipment emitting strong
electromagnetic fields that could distort the magnetic field
generated by the flowmeter and cause measuring errors.
P Do not install the meter body where vacuum conditions may exist.

Anderson Instrument Company 2-3
AIC 2071
Guidelines for properly locating the meter body are summarized in the
following table.

Installation Procedures
The meter body installation procedures must be tailored to the specific site
and the size of the flowmeter. Select a location for the meter body using the
guidelines discussed in the previous subsection.
Install the meter body with a minimum of 5 pipe diameters of straight,
unobstructed pipe upstream from the meter body and 3 pipe diameters of
straight, unobstructed pipe downstream when measured from the inlet and
outlet of the meter body. No tees, elbows, valves, check valves, or other
devices that may cause turbulent flow can be within these lengths of straight
pipe.

Figure 2-2. Meter Body Dimensions
To install the meter body:
1. Make sure the pipe section selected for the meter body has the proper
clearance and support for the meter body with connection adapters. See
Figure 2-2 and the table below for meter body dimensions and weight.
2. Place the meter body in-line with the arrow on the meter name plate
pointing in the direction of flow.
3. Clamp the meter body in the pipeline using standard connection gaskets
and sanitary clamps provided by the customer.

2-6 IZMSG Compact Electromagnetic Flowmeter
AIC 2071
Caution
Do not remove the meter body from the pipeline
by disassembling the connection adapters from
the meter body. Connection adapters should be
disassembled and assembled to the meter body
only after the meter body has been removed from
the pipeline.
Converter
The converter is shipped ready for installation. Verify that the converter
serial number matches the meter body serial number. The converter was
factory flow tested and calibrated with the accompanying meter body as a
matched set to the customer's specifications.
Caution
Never operate a meter body and converter with
different serial numbers. The flowmeter will
malfunction or operate improperly.
Location
Install the converter as close as possible to the meter body to avoid
extraneous inductive pick-up. Do not substitute any other cable for a factory-
supplied cable.
The standard factory-supplied cables are 25-feet long. If runs longer than
25 feet are required, contact Anderson Instrument Company. Do not splice
cables. For runs shorter than 25 feet, the cable must be trimmed to the proper
length. See Section 3, Making Electrical Connections, for instructions on
field preparation of cables.
Precautions that must be followed when selecting a location for the converter
include:
P Do not install the converter where the ambient temperature
exceeds 130°F.
P Do not install the converter where it may be exposed to extreme
vibration or direct sunlight.

Anderson Instrument Company 2-7
AIC 2071
P Do not install the converter near equipment emitting strong
electromagnetic fields that could distort the signals generated by
the flowmeter and cause measuring errors.
P Do not mount the converter in a direct hose wash-down area where
the unit may get wet or be exposed to cleaning compounds.
Installation Procedures
The converter installation procedures may need to be tailored to the specific
site.
To install the converter:
1. Make sure the converter has the proper power supply voltage configuration
for the specific installation. (See the information on power supply jumper
configurations in Section 3, Making Electrical Connections.)
2. Make sure the converter has proper clearance to open the converter cover
for installation and service (see Figure 2-3).
3. Close the cover of the converter. Tighten the screws on the front cover.
4. Mount the converter on the wall or panel using the mounting brackets.

Making Electrical Connections
Wire Openings and Connectors
Local code may require conduit for all or part of the wiring for the meter
body and converter installation. However, whether conduit or direct cabling
is used, the plugs on the meter body and converter must be removed and
replaced with either cord grips or conduit adapters. See Figure 3-1 and
following table for details.
Plug Each IZMSG meter body and converter is shipped with plugs and
seal rings at all entry points. When a plug is
removed, transfer its seal ring to the corresponding cord grip or
conduit adapter.
Cord Grip When properly used, this connection offers high resistance to
water intrusion by means of a sealing grommet which is
compressed against the outer cable sheath. All connections must
be tight and waterproof.
Conduit
Adapter
This connection consists of a threaded adapter to mate directly
with ½" NPT rigid conduit and liquid-tight conduit connectors. All
connections must be tight and waterproof.

Figure 3-2. Recommended Cable and Conduit Entry Methods
Figure 3-3. Converter Cable Openings
The recommended entry methods for cable or conduit are presented in
Figure 3-2. Never enter the enclosure from the top or sides. Create a
generous drip leg before each entry point to collect condensate from within
the conduit or cable. After wiring, fill any void with an approved silicone
sealant to ensure water tightness.
Use only the designated openings in the converter for the input and output
wiring (see Figure 3-3 for details). Do not substitute openings or create new
openings.

Figure 3-4. Meter Body Ground
Grounding the Meter Body
The meter body must be properly grounded. The lack of an effective earth
ground at the meter body will result in metering errors caused by extraneous
voltage at the electrodes.
Anderson Instrument Company recommends attaching a dedicated wire from
the 5mm (0.200") diameter ground lug on the side of the meter body to an
effective earth ground connection point. The ground wire should be of
sufficient wire gauge to provide zero resistance to the actual earth ground
connection point.
Connection Cables
Anderson Instrument Company provides two factory-ready connection cables
with the flowmeter. The electrode signal cable is a gray, 3-conductor
shielded cable (see Figure 3-5). The coil drive cable is a black, 2-conductor
shielded cable (see Figure 3-6).
Note: Standard cable length is 25 feet. It is specially designed for
the IZMSG Compact Flowmeter. The ends of the cable are
prepared according to factory specifications. Never substitute
any other cable for a factory-supplied cable. Do not splice
connection cables. Contact the factory for cable length
requirements that exceed 25 feet.

Figure 3-5. Electrode Signal Cable
Figure 3-6. Coil Drive Cable
Connection cables can be routed through a rigid, dedicated conduit using
water tight connectors at the meter body and converter enclosure. If desired,
both cables may be routed in the same conduit. Separate the cables into two
individual conduits adjacent to the meter body before routing the cables into
the field terminal box on the meter body.
Caution
Never bundle or route either the electrode signal
or the coil drive cable near any AC power line.
