The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes. 

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association. 

Magnetic inductive flowmeters or electromagnetic flowmeters are commonly called magmeters. The flowmeter referenced in this standard will be called a magmeter or magnetic flowmeter interchangeably. Magmeters are available in wafer style and threaded and flanged end connection designs. These spool/tube design flowmeters are most commonly used in the water industry. This standard will focus on magmeters of this design. 

This document does not discuss nor does it apply to the insertion type of magmeter. An insertion type is available for installation in large size pipe. A separate standard, or the inclusion in this standard, for the insertion type of magmeters may be developed by the AWWA Standards Committee on Rate Type Flowmeters. 

This document does not address specific issues where a magmeter would be used in revenue service. 

Major revisions made to the standard in this edition include the following: 

1. Information on chlorine and chloramine degradation of elastomers has been added to the foreword (Sec. II.B). 
2. Obsolete references on the evaluation of the health effects of products and drinking water additives have been removed from the foreword.
3. A number of editorial improvements have been made throughout the document to improve clarity.
