摘要: A Coriolis flowmeter is operable as a vibrating tube densitometer where flowtube driven to vibrate at fundamental frequency from which density of the material flowing through may be calculated. The drive gain monitored an indicator multiphase flow including gas and liquid components substantial increase in indicates damping vibrations due transient bubble entering flowtube. effects correspondingly reduced readings are remediated by use historical measurements corresponding periods when no has entered
