A VIBRATING DENSITOMETER INCLUDING AN IMPROVED VIBRATING MEMBER

摘要

An apparatus is provided that comprises a vibrating member (402). The vibrating member (402) is for a vibrating densitometer (400). The vibrating member (402) includes one or more apertures (420). The one or more apertures (420) are sized and located in the vibrating member (402) to increase a frequency separation between a resonant frequency of a desired vibrational drive mode and a resonant frequency of one or more undesired vibrational modes.
