Abstract (English):
The article is devoted to the problems of using flow meters with ultrasonic transducers in real operating conditions in the presence of deposits on the walls of pipelines. Methods of calculation and accounting of deposits in determining the flow rate of liquids are presented. Errors of flow rate and flow rate measurements depending on thickness of deposits for different pipe sizes were analyzed.
