“…Figure 6 shows the test results of the Coriolis mass flowmeter at the different working pressures from 10 to 40 bar when using the four sonic nozzles for the flowrate range from 1.0 kg/min to 4.5 kg/min. The pressure conditions of the incoming air from 10 to 40 bar correspond to the different density conditions of 12 kg/min 3 to 46 kg/min 3 . At each measuring point, three repeated measurements were carried out in different pressure and flowrate conditions.…”

“…A typical hydrogen refueling station consists of high-pressure compressors, storage tanks, a pressure ramp regulator, a pre-cooling system, and a hydrogen dispenser to dispense high-pressure hydrogen through a fueling nozzle that connects to a receptacle on the hydrogen fuel cell electric vehicle; an example of the layout of the hydrogen refueling 2 of 14 station is shown in Figure 1. Hydrogen refueling stations typically dispense high-pressure hydrogen gas of around 5 kg into the tanks of hydrogen vehicles, with wide span ranges of pressure and temperature [2,3]. A pre-cooling process to lower the temperature to −40 °C is done to prevent any substantial increase in the temperature of the compressed hydrogen gas during the fueling process, given that the pressure is as high as 70 MPa in the tank of the hydrogen vehicle.…”

Hydrogen fuel cell electric vehicles are emerging as a means of transportation using renewable and carbon-free energy due to global warming and air pollution. Hydrogen fuel cell electric vehicles are typically refueled at a wide range of temperatures (−40 °C to 85 °C) in hydrogen refueling stations in accordance with globally accepted standards. Currently, there is no traceable method by which to verify and calibrate the Coriolis mass flowmeters used at hydrogen refueling stations, except for a water calibration process as a conventional method for mass flowrate calibration. To verify the hydrogen flow metering to a suitable level of accuracy under the challenging condition of high pressures and a wide range of temperatures, necessary methodologies and calibration facilities are developed in the present study. A flow measurement characteristic test of the hydrogen mass flowmeter under identical density conditions of the refueled hydrogen was conducted using the high-pressure gas flow standard system of the Korea Research Institute of Standards and Science to assess the effects on the medium and pressure of the mass flowmeter in a density-matching approach. To investigate the pressure dependence of the mass flowmeter at a hydrogen refueling station, a high-pressure water flow test was conducted in the pressure range of 2 bar to 700 bar, which is a pressure-matching approach. Finally, the KRISS Hydrogen Field Test Standard based on the gravimetric principle was developed to verify the measurement accuracy of the mass flowmeter to be used at hydrogen refueling stations for the first time in Korea.

“…Bobovnik et al used this iterative coupling method to study the effects of disturbed velocity profiles due to installation effects for a short straight tube full-bore design ( 2013) and single and twin tube (2015). Pope and Wright (2014) conducted experiments to analyze the performance of Coriolis meters in transient gas flow using nitrogen and helium gases through two Coriolis meters at the National Institute of Standards and Technology's Transient Flow Facility. Both meters were capable of measuring the totalized mass from the transient flows within 1.0%.…”

Coriolis, turbine, V-cone, and orifice meters have been used in measurement of gas production in shale wells. Flange-tapped concentric orifice meters are commonly used in measurement of shale gas production volumes due to their low cost, accuracy, and ease of maintenance compared to other types of meters. However, shale gas wells are producing at high flow rates, high pressure, and possibly gas compositions change, which might affect volumetric measurement accuracy that was developed for conventional gas wells. Thus, it is critical to investigate the metering and measurements technologies that are being applied in shale gas wells to further understand and improve the accuracy of gas volumetric measurements. This paper provides a comprehensive review and analysis of background information, design, measurement, and uncertainties associated with Coriolis meters, turbine meters, V-cone meters, and orifice meters. We also discussed the lessons learned through our field experiences in computing gas volumes using SCADA information in shale gas and conventional gas production.

“…It was found from experimental investigations on a water flow test facility that, with appropriate flow tube design, improved meter drive and signal processing procedures, high dynamic performance CMF was achievable (Cheesewright and Clark, 2004;Clark and Cheesewright, 2006). Pope and Wright (2014) Nazeri et al (2016) studied transient conditions on a CO2 flow rig under start and stop operations using a CMF, but their work focused on gaseous CO2 flow in a 6 mm bore pipeline, the flow characteristics of which are far from those under CCS conditions. Gas-liquid twophase CO2 is expected in CCS pipelines due to the thermophysical properties of CO2 and the transportation conditions.…”
