Carbon Capture, Utilisation and Storage (CCUS) is a key United Kingdom Government strategy for reducing carbon dioxide (CO2) emissions to combat the potentially catastrophic effects of climate change. The UK aims to capture and store 10 million tonnes of CO2 each year by 2030. Across the entire CCUS value chain, each of the stages require accurate measurement of CO2 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...

The requirements for the refuelling process to minimise overheating and overfilling have a considerable influence on HRS design and have a substantial impact on prospective fuelling performance. Type approval of HRS is a complex, expensive and time-consuming process whereas on-field inspection should be quick, cost efficient, reliable, and easy to perform. This paper describes a secondary flow standard which could be used to meet those objectives. Through the implementation of secondary standard verification, type approval time willdrastically decrease from 2 days of testing (using the...

In order to study the dynamic response characteristics of liquid flowmeter, a dynamic flow device based on superposition principle is established. The device generates the main flow through the screw pump; The positive step or negative step flow component is generated by opening or closing the high-speed solenoid valve; and the Sinusoidal pulsating flow component is formed by the sinusoidal mechanism. The real step flow or pulsating flow can be formed by superimposing the step flow component or pulsating flow component on the main flow. The system is equipped with a weighing system to...

There are currently several mobile gravimetric standards for testing and calibrating hydrogen refuelling stations in operation. These standards are compliant for fuel delivery to light-duty vehicles according to the SAE J2601 protocol and provide measurement uncertainties that are low enough to use them for type-approval testing according to OMIL R139 recommendation. An international field comparison under real conditions is requiredto ensure a complete acceptance of test results by operators and notified bodies. In this paper, we will present details on a currently running comparison to...

In this paper, we present the strategy behind the design and manufacture of sets of Critical Flow Venturi Nozzles (CFVN) with various sizes, shapes and surface roughnesses, as well as their dimensional calibration to test the applicability of ISO 9300 for high-pressure hydrogen aplications. Some of the built nozzles and nozzle holders will be used for high-pressure measurements with hydrogen and underwent a baseline metrological check at lower pressure using inert gases to ensure that their low-pressure characteristics are known before performing the measurements with high-pressure hydrogen....

A numerical model was performed to represent the expansion phenomenon resulting from the leakage of pressurized gases in a pipe using the Ansys Fluent 2021 R1 software. The free underexpanded jet was produced by a nozzle with an outlet diameter of operating at a stagnation pressure and temperature respectively equal to and , being compared with the experiment conducted by Eggins and Jackson (1974) for qualitative (visual analysis) and quantitative validation requirements (through the statistical model proposed by Hanna (1993)). After the validation of the proposed numerical model, some...

The piston type micro liquid flow standard device is a kind of flow standard device with volume-time method. Because it can easily obtain micro flow due to its working principle, this kind of standard device is widely used in micro flowrate value traceability. In addition, the rapid development of precision machining technology also makes the processing of the piston, the master standard in the piston flow standard device, more and more precise, which plays a significant role in reducing the uncertainty of the whole standard device. In this paper, the simplified geometric model of the piston...

Whether the measurement performance of flow standard facility is normal or not directly affects the final flow measurement result, and the independent checking of quantity value is the key technical means to ensure the steady and reliable performance of flow calibration system. At present, there is a lack of quantitative verification methods for liquid flow standard facilities, and the existing researches mostly focus on expanding the range of operating parameters of facilities and improving their uncertainty level, etc, while the quantitative verification for flow facilities themselves has...

The applications of portable clamp-on ultrasonic flowmeters in on-line detection have lots of advantages. However, the measurement accuracy of ultrasonic flowmeters is often affected by various factors, such as pipe characteristics, flow fields and fluid medium. In this work, both experiments and CFD simulations are carried out to study the flow field changing caused by valves, and the influences of valve opening on measurement accuracy for ultrasonic flowmeters. The experiment results showed that, with the decrease of valve opening, the value of repeatability of indication error is...

There are many limitations for the accuracy assurance technology of large-diameter heat meters characterized by laboratory calibration mode, which is hard to adapt to the complicated situation of heating system in China. Aiming to improve the measurement data accuracy of heating system thermal quantity, this paper proposes a new technical method by installing elbow sensor in the natural heating pipe bend to obtain the exact measure reference value. The method is based on the studies of current quality control conditions of big-diameter heat-meters, the flow measuring capability of...
