SUBJECT:    Accurate Metering System, Inc IZMS Electromagnetic Flow Measuring
	           System for Use as a Magnetic Flowmeter
 
 
The IZMS Electromagnetic Flow Measuring System has been reviewed and found to
comply with the applicable provisions of the Grade "A" Pasteurized Milk
Ordinance (PMO) when used as a flow-measuring device.
 
Compliance with the PMO is based upon construction, installation, and operation
as described in the manufacturer's manuals IM-IZMS 0297 and IM-IZMS-short
form-0400, as well as the following provisions:
 
1. The Flowmeter shall be installed in compliance with the criteria for Magnetic
Flow Meter Based Timing Systems for HTST Pasteurizers, Components and Placement
of Components Sections as cited in Appendix H of the PMO.
 
2. The meter based timing system shall comply with the requirements for meter
based timing systems as cited.
 
3. The configured values will be documented by the manufacturer and maintained
so that the operator and/or Regulatory Agency can verify these values.  The
Regulatory Agency should maintain a copy for their files. After the
configuration values have been verified, the cover of the converter is replaced.
Access to the electromagnetic flowmeter   transmitter shall be restricted by the
application of a regulatory seal.
 
4. When installed, the magnetic flowmeter sensor and transmitter shall comply
with all applicable test requirements in Appendix I of the PMO for magnetic flow
meter based timing systems.
 
The technical information that was reviewed constitutes the Accurate Metering
System Engineering Design and Technical Construction File.

FDA's review and acceptance of this Electromagnetic Flow Measuring System does
not constitute agency endorsement or approval.  Any representation on a label or
in printed literature citing or indicating "FDA Approved" is false and
misleading.
 
Copies of this memorandum are enclosed for distribution to Regional Milk
Specialists, State Milk Regulatory Agencies and State Milk Sanitation Rating
Officers in your region. This memorandum will also be available on the FDA Web
site at http://www.cfsan.fda.gov at a later date and should be widely
distributed to representatives of the dairy industry and other interested
parties.

DISPLAYING IZMS FLOW RATE
 
 
To view the current flow rate of the IZMS meter if the flow register is not
already displayed, depress and release the "up" arrow until the lower display
changes to "Q ---gal/min", This display is the measured flow rate of the meter.
Note: no more than 3 key pushes should be necessary to display the flow rate.
 
 
To view the programmed maximum flow rate of the flowmeter, depress and release
the menu [§] key, then depress and release the number "0" and depress and
release the number "3". This will change the display to the Qmax value, which is
the meters maximum flow rate, and also the rate at which it produces 20 mA. The
Qmax value will be displayed for approximately 2 minutes and the display will
revert back to the operation display.
