  • Effect of Meter Orientation Downstream of a Short Radius Elbow on Electromagnetic Flow Meters
    Hosted by Utah State University Libraries, 2018
    Co-Authors: Justensen, Jared C., Barfuss, Steven L., Johnson, Michael C., Meacham, Thomas E.
    Abstract:

    Electromagnetic flow meters (known as magnetic flow meters) are a widely used type of flow meter. This study examines the performance of magnetic flow meters when the electrodes in the meter are positioned at two different orientations: electrodes parallel with the plane of an upstream 90° short Radius Elbow and electrodes perpendicular to the plane of an upstream 90° short Radius Elbow. Four different meters from four different manufacturers were included in the study in which a baseline straight pipe test was first performed using more than 50 diameters of straight pipe upstream of each meter. The four meters were then installed at five different locations downstream from a 90° short-Radius Elbow. At each location, the meters were tested in two orientations at five different flow rates. From this study, shifts in the flow rate were observed with the electrodes located at two different orientations. These shifts in flow rate ranged from 0.01% to 4.40% of the total flow measurement, and the average shifts in flow rate ranged from 0.07% to 2.78%. For the purposes of this study, the shift in flow rate is the percentage relative to the baseline test. The results from this study illustrated that there is a significant difference in measurement accuracy when the meter electrodes are installed at different orientations relative to the plane of the bend

  • AIM - Forearm skeleton modeling for pro-/supination movement using CT image measurement
    2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015
    Co-Authors: Kousei Nojiri, Takuya Kiyokawa, Yoji Okayama
    Abstract:

    Utilization of the digital human has been tried for the human work-related evaluation for industrial products and the prevention of an injury during sports activity. The human modeling for the posture generation of digital human are studied actively. In this study, we aim for the construction of the skeleton model for forearm pro-/supination to be performed in everyday life frequently. The forearm skeleton of the present digital human is comprised of 1 link, therefor we cannot estimate the movement of the forearm bone exactly. As the pro-/supination model of the forearm skeleton, there are the models Fick and others and Kecskemethy and others proposed. This model is comprised of 4 closed link of ulna, Radius, Elbow side junction and wrist side junction such as human forearm skeleton. In this paper, by analyzing CT imaging of the forearm, we proposed the newer forearm skeleton model based on biomechanics.
