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.

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.

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

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).

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.
