 Summary:
 In 2015 it has been proven that the unsubmerged thin-plate weir of height equal 20 cm, with an artificial finger installed, is suitable for measuring flow hydrographs. The essence of fitting the weir for the task is fixing the discharges of adhesion and separation. This is an innovative statement comparing to the current ones of the international standards regarding thin-plate weirs. This paper presents the results of investigations carried out in the Hydraulic Laboratory of the Faculty of Civil Engineering in Subotica, Serbia, concerning measurements of flow hydrographs by the means of unsubmerged, full-width, thin-plate weirs of different height.
