Motion induced signals of Coriolis flowmeters

摘要

Rotation induced Coriolis flowmeter output was observed in a robotic fluid dispensing test. This motion sensitivity of Coriolis flowmeters was confirmed to be universal for various noninertial reference frames. It was also confirmed that this motion sensitivity is a general aspect of many Coriolis flowmeter types. Qualitative tests revealed that the motion induced signals appear to be proportional to frame rotation rate and are strongly dependent on the flow tube oscillation velocity vectors.
