“…The results of the aforementioned authors’ finite-element analysis were consistent with their experimental results, which indicated that the finite-element method can provide an accurate numerical simulation for a CMF. Drahm and Bjonnes [ 9 ] proposed a method that can use drive current magnitude to estimate fluid viscosity. Kumar et al [ 10 ] analyzed the flow field state for a low Reynolds number ( Re ) and proposed that the flow state at a low Re may cause deviation in measurement.…”

Coriolis mass flowmeters are highly customized products involving high-degree fluid-structure coupling dynamics and high-precision manufacture. The typical delay from from order to shipment is at least 4 months. This paper presents some important design considerations through simulation and experiments, so as to provide manufacturers with a more time-efficient product design and manufacture process. This paper aims at simulating the fluid-structure coupling dynamics of a dual U-tube Coriolis mass flowmeter through the COMSOL simulation package. The simulation results are experimentally validated using a dual U-tube CMF manufactured by Yokogawa Co., Ltd. in a TAF certified flow testing factory provided by FineTek Co., Ltd. Some important design considerations are drawn from simulation and experiment. The zero drift will occur when the dual U-tube structure is unbalanced and therefore the dynamic balance is very important in the manufacturing of dual U-tube CMF. The fluid viscosity can be determined from the driving current of the voice coil actuator or the pressure loss between the inlet and outlet of CMF. Finally, the authors develop a simulation application based on COMSOL’s development platform. Users can quickly evaluate their design through by using this application. The present application can significantly shorten product design and manufacturing time.

“…This excitation current is dampened as a result of the shear forces occurring in the process concentrate. Hence, the viscosity of the process concentrate can be determined from the excitation current (Drahm & Bjonnes 2003). An example of a commercial meter that uses this principle is available from Endress + Hauser (Proline Promass I 300 / 83I).…”

The ideal PAT tool is an inline instrument that can monitor and measure process parameters simultaneously in real time while operating in a highly automated environment. Instruments must be of sanitary design, operate robustly within the full process cycle (production and cleaning). Inline determination of the rheological properties of moving fluids (i.e. dairy concentrates) is one of the process parameters where PAT tools can be add real value in terms of optimising process control. Measurement of process viscosity is crucial in the monitoring and control of a variety of concentration processes in the dairy industry. Continuous monitoring of the rheological behaviour of the fluid can allow for optimisation of the process e.g. pumping (avoid pump blockage and failure), evaporation (limit fouling and maximise water removal) and spray drying (avoidance of nozzle fouling). This review concentrates on the state of the art developments being made in the area of process viscometry.

“…However, still, bunker fuel entails high viscosities which may compromise CMF measurement accuracy. It has been shown that of all the fluid properties, fluid viscosity prominently and greatly hinders the performance of CMFs (Drahm & Bjonnes, 2003;Dutka et al, 2004;Kalotay,1994;. Moreover, studies have elucidated that most CMFs are plagued by relatively large inaccuracies at low Reynolds numbers (Rongmo & Jian, 2013).…”

“…As a very first step towards the mitigation of CMFs' error due to fluid's viscosity, researchers opted for monitoring the variations of viscosity in an attempt to understand how the viscosity affects the measurement process and hence the measurement accuracy. In fact, Drahm and Bjonnes (2003) characterized the CMF by integrating it with viscosity measuring systems. They commented that CMFs, which are intrinsically multivariable devices when integrated with viscosity measurement acquire even more functionalities.…”

A Coriolis Mass Flowmeters (CMFs), outperform other flow measurement systems owing to their perceived high accuracy and good repeatability. That has attracted its use in different fields including the bunkering industry. Bunkering operations entail high viscosity flows that may limit the applicability of high accuracy CMFs. Furthermore, their performance for measurement of single-phase high viscosity flow remains less explored and the mechanisms responsible for possible additional measurement error due to high viscosity fluid are not thoroughly studied. This study characterizes the performance of CMFs on the measurement of high viscosity fluid via CFD simulations. It is observed that the error of CMFs on measurement of high viscosity is deemed relatively large at low mass flow rates and which monotonically increases as the viscosity increases. The sudden pressure increase and secondary flow in the vicinity of the flow sensors’ locations are the key factors influencing the measurement discrepancy. It is worthy to note that this study is highly significant to the bunkering industry as it can serve as a baseline for further experimental works on the measurement of bunker fuel oils.
