20140260622 | Apparatus for gauging liquid or solid mass contained in a vessel and method for using same - The basic physical principle of the Apparatus for Gauging Liquid or Solid Mass Contained in a Vessel and Method for Using Same (MAGA) is the detection of a resonant frequency vibration mode or modes associated with the spring/mass system comprising the vessel/fluid, vessel support structure, and physical supports, when an excitation source is present. The excitation produces a relative displacement between the fluid containment vessel and its support frame or other fixture to which it is fastened. The displacement produces a signal voltage in one or more of the sensors, such as strain gauge devices or accelerometers, which are attached to the fluid containment vessel, its physical supports, or the support structure, shell or frame. The frequency and amplitude of the sensor signal varies in accordance with known physical principles that relate the amplitude of vibration and the frequency of vibration to the masses and spring constants of the spring/mass system. Either the amplitude or frequency of the resonant vibrations or both amplitude and frequency can be used to determine the unknown quantity or mass of the fluid in the fluid containment vessel. Alternatively, a means for determining the resonant frequency as measured from the observation of the relative displacement of the vessel and its support structure vs. time, for example, using a laser positioning device, can be used to determine the unknown quantity or mass of the fluid in the fluid containment vessel. In contrast with other low-g mass gauging methods that typically require an accurate knowledge of the secondary properties of the fluid, the present method uses fundamental physical principles that relate the observed resonant vibration modes directly to the system masses. Therefore, for a given mass of fluid in the fluid containment vessel, the resulting amplitudes and resonant frequency modes are identical even if the fluid secondary properties, such as density, viscosity, and surface tension, are substantially different. This differentiates MAGA from similar mass gauging systems that a) depend on a precise knowledge of fluid secondary properties that may vary with temperature and/or pressure; or b) require external hardware apparatus or test masses to determine the unknown fluid mass. | 2014-09-18 |
