The process-oriented liquid itself might influence the performance of the flow device. Therefore, the calibration of the flow meter or microfluidic device with the process-oriented liquid is important and the simultaneous determination of the dynamic viscosity under flow conditions is a valuable information for viscosity dependent flow metering methods or other process parameters. To offer the simultaneous calibration of the dynamic viscosity of the process-oriented liquid at the corresponding flowrate, METAS has built a pipe viscometer for the traceable in-line measurement of the dynamic viscosity in the current flow facilities for low flow rates from 1  L/min to 150 mL/min and pressure drops up to 10 bar. To guarantee the tracability, the most challenging part remain the determination of the inner diameter of the micro tube. This can be determined by measuring the pressure drop as a function of flow rate and applying the law of Hagen-Poiseuille with a well known liquid (water) or perform the measurements with the  -CT at METAS, which determines the inner diameter by x-ray diffraction. The setup of the facility, the uncertainty calculation for the in-line measurement of the dynamic viscosity and the validation measurements are discussed in this paper.","PeriodicalId":62400,"journal":{"name":"流量控制、测量及可视化(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86992684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The UK aims to capture and store 10 million tonnes of CO 2 each year by 2030. Across the entire CCUS value chain, each of the stages require accurate measurement of CO 2 at temperatures, pressures, flow rates and fluid phases that must be validated through a credible traceability chain for flow. This traceability chain would provide the underpinning confidence in meter performance, financial and fiscal transactions and, critically, environmental compliance. The UK-adopted version of the EU Emissions Trading System (EU ETS) has specified an uncertainty value for CO 2 flow measurement that must be adhered to. Accordingly, the provision of accurate and traceable flow measurement of CO 2 in the UK and internationally will be essential for the successful operation of CCUS. Unfortunately, there are currently no CO 2 flow measurement facilities in the world that are capable of traceable flow calibrations of gas phase, liquid/dense phase and supercritical phase CO 2 that replicate real-world CCUS conditions. The absence of traceable CO 2 gas and liquid flow measurement facilities and accompanying national or international flow measurement standards could seriously impede the widespread deployment of CCUS. These significant barriers could potentially jeopardise the successful implementation of CCUS projects worldwide, not least because these will be governed by legislation and environmental regulations requiring traceable measurement. This paper presents an overview of the current traceability chain for CO 2 flow measurement in the UK and globally. Current challenges will be detailed along with potential solutions and opportunities for the measurement community.","PeriodicalId":62400,"journal":{"name":"流量控制、测量及可视化(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91107537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And flow rate is one of the most important parameter in this process. One traditional method of deriving flow rate is measuring the pressure difference (DP) along the pipe while the concerned fluid flowing through a DP instrument, such as Venturi meter. This DP instrument is among the most widely used flow measurement instruments, available in plumbing, energy transport pipeline, petroleum chemical industries, etc. In this research, a non-standard Venturi structure is proposed to satisfy the measurement demand of the inlet multi-phase flow with complex flow pattern. Compared to the standard Venturi meter, the angles of the divergent and the convergent of the proposed device are changed to obtain a shorter pipeline. Besides, a swirler is also placed into the convergent, which would force the flow to swirl with tangential velocity and adjust the inlet gas-liquid two phase flow to annular flow. The focus of the study is directed toward the pressure profile and the discharge coefficient Cd of the proposed structure. Computational simulation of single phase flow is carried out to measure the pressure drop along x-axis via FLUENT. According to the simulation results, the addition of swirler brings an extra pressure drop in advance. At the end of the throat, there is a sudden drop of pressure, decreasing to the lowest point, which is caused by the characteristics of the precession vortex. Then the final static pressure value is obviously lower than the initial static pressure value.","PeriodicalId":62400,"journal":{"name":"流量控制、测量及可视化(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89311288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
