Meters

AWWA meter standards cover the C700 series, which cover a variety of water meter types including displacement, turbine, compound, fire service, propeller, multi- and single-jet, fluid-oscillator, and ultrasonic types. In addition, the calibration methods and verifications for meters in different conduits and magnetized flowmeters for residential and commercial buildings are addressed.

Magnetic Inductive Flowmeters

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