<p>The article discusses the issues of measurements of water consumption in water <br /> management systems, which is regarded as one of the most pressing problems nowadays. The <br /> UR-6 A irrigation canal, which brings water from the Mirishkor main canal, was selected <br /> as the subject of the study. The fi eld studies carried out at the PK-1 + 00 picket of the UR-6 <br /> A irrigation canal, together with hydrometers of the Mirishkor irrigation systems control <br /> using a GR-21m1 spinner as well as a SonTek S5 doppler, analyzed the degree of accuracy <br /> of the two measuring instruments, the ease of their use at the measurement site as well as <br /> economic efficiency. According to the measurements, the average water fl ow, determined by the hydrometric spinner, was Q = 2.39 m3/s, the average water fl ow, measured using the <br /> Doppler tool, was Q = 2.261 m3/s.</p>
