ULTRASONIC MEASUREMENT TECHNOLOGY IN AUTOMATED CONTROL OF WATER RESOURCES

Control of water resources is becoming an important strategic issue. That why authorities set the goal for wa-ter agencies to manage availability and create regulations its rational use. The main point in control measurement. There are three aspects measurements resources: at extraction from nature, consumption custody transfer. sometimes based not on measurements, but preliminary estimation, example, by pumping.
 Ultrasonic measurement technology as a key feature automated has potential role this market. In contrast mechanical (turbine) meters, ultrasonic meters have priority because they also give possibility realize smart metering. electromagnetic which measure with high accuracy functions, much more suitable rough water, wastewater sewage. Such usually poorly controlled, means that no one knows their exact cost.
 Measurement mandatory cost billing. Accuracy issue, especially when we say about large pipe diameters. practically alternative flow meters. Market diverse concentrated diameters under 400 mm. For larger diameters, only They many chords, difficult algorithms data processing. Thus, applicable over very wide range.
 paper, discover transit-time understand features theory taking into account all factors affecting work. This article describes errors inherent these flowmeters during measurements.
 As far significantly billing, 1% error small (DN50÷DN150 mm) (DN200÷DN1200 been evaluated analyzed. losses installation low-quality metering devices demonstrated discussed.
