Coriolis flowmeters: a review of developments over the past 20 years, and an assessment of the state of the art and likely future directions

Abstract

This paper starts from a brief revisit of key early published work so that an overview of modern Coriolis flowmeters can be provided based on a historical background. The paper, then, focuses on providing an updated review of Coriolis flow measurement technology over the past 20 years. Published research work and industrial Coriolis flowmeter design are both reviewed in details. It is the intention of this paper to provide a comprehensive review study of all important topics in the subject, which include interesting theoretical and experimental studies and innovative industrial developments and applications. The advances in fundamental understanding and technology development are clearly identified. Future directions in various areas together with some open questions are also outlined. Highlights:  A brief revisit of key early published work is provided.  An updated review over the past 20 years is presented.  Published research work and industrial Coriolis flowmeter design are both reviewed.  Advances in fundamental understanding & technology development are identified.  Future directions together with open questions are outlined.

Vibration isolation for coriolis mass-flow meters

“…Alternatively and even better, the tube displacement y cor can be used as error sensor. 78 Chapter 4 CMFM with integrated Active Vibration Isolation Control…”

“…This principle can be used for true mass-flow measurements, in which the measured parameter is directly related to mass-flow, independently of the fluid properties. Market research studies show an increasing acceptance of the CMFMs by various industries, making it one of the fastest growing flow meter markets [20,78].…”

“…Further Bobovnik et al [5,6] studied the effect of disturbed velocity profiles due to the shape of the fluid supply tubes and other influencing factors like two-phase or even three-phase flow effects were studied by Henry et al [29]. Wang and Baker [78] discussed recently also the different signal processing and control techniques. Recent developments in digital hardware bring improved performance, which actually affects the measurement value.…”

“…A Coriolis Mass-Flow Meter (CMFM) is an active device based on the Coriolis force principle for direct mass-flow measurements independent of fluid properties [1,78]. The CMFM contains a fluid-conveying tube.…”

“…In this paper an active vibration isolated measurement system applied to a Coriolis Mass-Flow Meter (CMFM) is presented. A CMFM is an active device based on the Coriolis force principle for direct mass-flow measurements independent of fluid properties [1,78]. The CMFM contains a fluid conveying tube, which is actuated to oscillate in resonance with a low amplitude.…”
