Abstract

Устройство (10) для потока текучей среды, включающее цельный элемент (42) для отклонения потока текучей среды, установленный с возможностью извлечения в секции трубопровода (20) для текучей среды таким образом, что не используется никакого соединения материалов. Отклоняющий элемент установлен в секции трубопровода с возможностью извлечения и замены таким образом, что один отклоняющий элемент может быть заменен одним или более другими отклоняющими элементами, и в результате этого может быть обеспечено приспосабливание к очень широкому диапазону потоков текучих сред. Установочное приспособление или опора (44) предусмотрена на расположенном ниже по течению конце отклоняющего элемента, что обеспечивает устранение возмущения в потоке текучей среды вокруг отклоняющего элемента и тем самым обеспечивает получение высокоустойчивого сигнала. Сигнал передается через предназначенные для измерения выпускные отверстия (24, 26) в стенке трубопровода, так что не требуется никаких выпускных отверстий, предназначенных для измерения, выполненных в отклоняющем элементе или проходящих сквозь него.Международная заявка была опубликована вместе с отчетом о международном поиске.
