FIELD: measuring devices.SUBSTANCE: invention relates to system and method for ultrasonic measurement of flow rate. In one embodiment measuring system for ultrasonic measurement of flow rate has a plurality of ultrasonic flow meters. Each of ultrasonic flow meters comprises data processing device flow. Data flow processing device is configured to store multiple intervals speed, each of which corresponds to range of flow speeds of flow meters. Data processing device also has possibility of storing, within each of them, values describing previous average speed of fluid medium flow through flow meter of flow meters, connected with given interval of specified intervals. Data processing device flow is further configured to determine reaction to failure of one of flow meters, expected average fluid flow rate through system based on values stored in intervals.EFFECT: technical result is improvement of accuracy of measurement of flow and protection against failures.30 cl, 7 dwg, 3 tbl |
