The objective of work was research of the measuring complex working by the slope-area method and his comparison with the main method of measurement of a consumption of water on open channels of irrigating systems speed-area. For experimental data measurements of hydraulic elements and the slope is calculated and the flow of water via a torque tube mating structures. By results of field researches of a measuring complex on a site of the canal in the earth course, with length of L = 147 m, the maximum relative error of measurement of a consumption of water has made δQmax = 2.9% against δQmax = 4.8%. On the basis of the obtained data it is possible to draw a conclusion that the developed measuring complex for definition of a consumption of water on the offered way (the error of measurement makes 0.001 m) gives the chance of his use in works of research character, and also on open channels of irrigating systems for the organization of the automated water account.
