“…To meet the requirements on more accurate measurements of the viscous heavy oil streams for allocation and custody transfer purposes, some innovative measurement methods, such as ultrasonic flow meter, electromagnetic flow meter, are investigated. The Coriolis mass flow meters are relatively modern flow measurement technologies and continue to capture increasing market share as operators gain confidence in their performance [4]. This paper describes a liquid flow measurement primary standard.…”

“…Качественно понятно, почему в этом режиме нарушается работоспособность КМР: распределение массы флюида вдоль измерительной трубки становится существенно неоднородным и изменяющимся во времени случайным образом, что ведет к случайным же изменениям наблюдаемых параметров колебаний -основной частоты колебаний трубки и фазового сдвига между колебаниями ее плеч. В настоящее время предложен эмпирический метод решения этой задачи, позволяющий получать надежные результаты для потоков, где объемная доля газовой фазы достигает 80 % [9][10][11]. В то же время отмечается, что дальнейшее совершенствование метода требует более глубокого понимания механизмов взаимодействия двухфазного флюида с измерительной трубкой КМР и разработки соответствующих физических моделей, позволяющих предсказывать отклик прибора на двухфазный поток.…”

“…This changes the optimal controller structure C FF (s) for a a 0,z -disturbance. The ideal controller structure for a z-disturbance is: 29) where the stiffness k, damping d and gain g can be determined by the system identification (Section 4.5.2). The main difference between Eq.…”

“…And more recent also by Kazahaya [35]: uneven flow rates in two flow tubes, vibration effects, temperature effects and the inner pressure effects. Further Bobovnik et al [5] studied the effect of disturbed velocity profiles due to installation effects and other influencing factors like two-phase or even three-phase flow effects were studied by Henry et al [29] In our research we focus mainly on the effect of floor/mechanical/external vibrations. These vibrations create additional components in the CMFM sensor signals [14], those additional components can introduce a measurement error.…”
