Warranty
Anderson Instrument Company warrants to the original purchaser that
equipment manufactured by Anderson Instrument is free from defects in
material and workmanship for one (1) year from date of shipment. Anderson
Instrument guarantees to repair or replace any of its equipment found
defective, provided written notice of the defect is received within one year
from date of shipment. Shipping charges to or from Anderson Instrument for
new, replacement, or repaired equipment are not considered part of the
warranty and remain the responsibility of the purchaser.
This warranty does not cover damages caused
by ordinary wear and tear, erosion or
corrosion, or misuse, abuse or improper
handling. The warranty is void if a customer
modifies or services the flowmeter physically or
electronically in any way.
Anderson Instrument makes no additional warranties, expressed or implied,
whether of merchantability or otherwise, other than that stated above.
Anderson Instrument shall not be responsible beyond the remedy stated
above for any indirect, special or consequential damages, or for any other
claim arising out of the sale or use of its equipment.
Equipment, parts, or accessories manufactured by others carry the guarantee
of the manufacturer only. Any warranties or claims which differ from the
foregoing are unauthorized by Anderson Instrument and become the
warranty solely of the party making them, unless specifically authorized in
writing by an officer of Anderson Instrument Company
Should any provision of the foregoing be held ineffective, the remaining
provisions shall continue in full force and effect.

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.
The major items are:
P meter body with connection adapters assembled to the flow tube
P converter with plugs and polyethylene seal rings at all wire entry
points
P cord grips and conduit adapters (separate bag)
P electrode signal cable (25-ft standard length)
P coil drive cable (25-ft standard length)

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

(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).
Circuit Boards

There are three circuit boards inside the converter: 300-SMB1 Main Board
(Figure 1-3); 300-SACPSB AC Power Supply Board (Figure 1-4); and 300-
SJB2 Junction Board (Figure 1-5). In a converter with the optional display and
keypad, there is a fourth circuit board, 300-SDKB (Figure 1-6).

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.

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.
