Annotation:
The paper briefly describes the design and operational principle of ultrasonic flow meters. The role of flow meters in the fight against leaks in a pipeline is analyzed. Leaks are classified according to the cause of their occurrence. The process of collecting the readings of ultrasonic flow transducers with the assignment of time stamps and uploading the received data to the information processing system and then to the dispatching control and management system is described. Possible cases of malfunction of ultrasonic flow meters are described using the example of an array of flow rates values presented for a monthly period. Analytical dependences are given that allow determination of the criticality of a malfunction within the established error of ultrasonic flow meters. The algorithm of a possible scheme for remote calibration using a reference ultrasonic flow meter, tanks of the tank farm, as well as using systems for measuring the quality and quantity of oil, indicating the calibration tools with the permissible relative and absolute errors is given.
