Publication date:   Jul 16, 1992

Scope

Specifies procedures for the establishment and operation of a gauging station, equipped with an electromagnetic flow-meter, in an open channel or a closed conduit with a free water surface. The field of application is limited to sites where the magnetic field is generated by an electromagnetic coil which traverses the full channel width. Does not apply to flow-meters which operate by using the Earth's magnetic field.
