scope:

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 standard does not apply to the insertion type of magmeter. This standard does not address specific issues where a magmeter would be used in revenue service.

Purpose

The purpose of this document is to review magnetic inductive flowmeter (magmeter) principles of operation, calibration, and selection.
