Defines guidelines for the selection, design and use of electromagnetic current meters to determine point velocity 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).
