17、ndard ANSI/AWWA C751-16 (First Edition) Magnetic Inductive Flowmeters SECTION 1: GENERAL Sec. 1.1 Scope Magnetic inductive flowmeters or electromagnetic flowmeters are commonly called magmeters. The flowmeter referenced in this standard will be called a mag- meter or magnetic flowmeter interchangeab

18、ly. Magmeters are available in wafer style and threaded and flanged-end connection designs. These spool/tube design flow - meters 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

19、 of mag- meter. 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 at a later date 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. Sec. 1.2 Purpose The purpose of this document is to review magnetic inductive flowmeter (magmeter) principles of operation, calibration, and selection.
