Measurement of liquid velocity in open channels — Design, selection and use of electromagnetic current meters

This Technical Specification gives guidelines for the design, selection and use of electromagnetic current meters

used to determine point velocity for the purpose of measuring flow in an open channel using the velocity area

method.

NOTE The electromagnetic current meter is acceptable as a device for making point determinations of velocity for the

purposes of open channel flow determination by the velocity area method, using the multiple point velocity sampling technique

described in ISO 748 (see reference [1] in the Bibliography).
