    Aug 17, 2001
  • Appl. No.:
    09/931002
  • Inventors:
    Manus P. Henry - Oxford, GB
    David W. Clarke - Oxford, GB
    James H. Vignos - Needham Heights MA
  • Assignee:
    Invensys Systems, Inc. - Foxboro MA
  • International Classification:
    G01F 100
  • US Classification:
    702 45, 73861355, 73861356
  • Abstract:
    A digital flowmeter includes a vibratable conduit, a driver connected to the conduit and operable to impart motion to the conduit, and a sensor connected to the conduit and operable to sense the motion of the conduit. A control and measurement system is connected to the driver and the sensor. The control and measurement system includes circuitry to receive a sensor signal from the sensor, generate a drive signal based on the sensor signal using digital signal processing, supply the drive signal to the driver, and generate a measurement of a property of a two-phase material flowing through the conduit based on the signal from the sensor.

  • Filed:
    Dec 13, 2004
  • Appl. No.:
    11/009511
  • Inventors:
    Wade M. Mattar - Wrentham MA, US
    James H. Vignos - Needham Heights MA, US
  • Assignee:
    Invensys Systems, Inc. - Foxboro MA
  • International Classification:
    G01N 9/00
    G01N 7/00
    G01N 29/00
  • US Classification:
    73 1903, 73 32 A, 73 6147, 73 6178, 73 6179
  • Abstract:
    Techniques for measuring a density of a liquid within a fluid that includes both a liquid and a gas are described. A pressure of the fluid oscillates according to a time-varying function, which causes a density of the fluid also to oscillate according to the same time-varying function. A resulting pressure signal and density signal are analyzed to extract at least a first and second pressure value and at least a first and second density value, where the first pressure and density values occur at a first time, and the second pressure and density values occur at a second time. Then, the liquid density is calculated from the first and second pressure and density values. As a result, the liquid density may be calculated quickly and easily, with a minimum of effort on the part of an operator, and without requiring disruption of other measurement processes associated with the flowtube.

  • US Classification:
    702 45, 73861355, 73861356
  • Abstract:
    A controller for a flowmeter includes an input module operable to receive a sensor signal from a sensor connected to a vibratable flowtube. The sensor signal is related to a fluid flow through the flowtube. The controller also includes a signal processing system operable to receive the sensor signal, determine sensor signal characteristics, and output drive signal characteristics for a drive signal applied to the flowtube. An output module is operable to output the drive signal to the flowtube and a control system is operable to modify the drive signal and thereby maintain oscillation of the flowtube during a transition of the flowtube from a substantially empty state to a substantially full state.

  • International Classification:
    G01F 1/00
  • US Classification:
    702 45
  • Abstract:
    Two-wire transmitters are described in which the required voltage that a control room must supply to the transmitter is lower at high current than at low current, thus freeing up more voltage for other uses, and in which a constant set of operating voltages may be maintained. A corrected pressure in a vortex flow meter may be determined that reflects the mass flow rate. Thus, the mass flow rate may be determined based on the corrected pressure reading and a measured volumetric flow rate. Density may be determined from pressure and temperature using a table containing error values based on a standard density determination and a relatively simple approximation. During operation of a flow meter, the stored error values may be linearly interpolated and the approximation may be computed to determine the density from the stored error value.
