摘要： A system (300) that provides a remote ordering system for a flowmeter. The system is embodied by a server (230, 250). The server receives input flow stream parameters (415) from a remote client computer. The server then determines (420) flowmeter parameters from the input flow stream parameters received from the remote client computer. The server then determines (425) at least one model of flowmeter suitable for the flowmeter parameters. The suitable models of flowmeters (440) are then transmitted to remoter computer where a customer may then place an order (460) for one of the models suitable for the flowmeter parameters. The flowmeter may be a Coriolis flowmeter.

摘要： An apparatus (150) and method (300) for determining a density compensated flow rate of a material flowing through a vibrating conduit. Signals are received from sensors (105, 105') affixed to the vibrating conduit (103A, 103B). An uncompensated flow rate and the density of said material is then calculated from the signals. The calculated density is then compared to a threshold density. If the calculated density surpasses the threshold density, the density compensation factor is determined by inserting said uncompensated flow-rate and said calculated density into a two dimensional N order polynomial equation relating density to flow rate error data wherein N is greater than 1. If the calculated density does not surpass the threshold density, the density compensation factor is determined by inserting said uncompensated flow rate and said calculated density into a linear equation relating density to flow rate error data. The density compensated flow rate is then dmpensated flow rate.

摘要： A universal booster amplifier (30) for a Coriolis flowmeter. The booster amplifier receives drive signals from a flowmeter electronics (20) and extends conditioned drive signals to a driver (104) for flow tubes (103A, 103B) of a flowmeter sensor (10). The booster amplifier includes phase shift circuitry (301) to provide improved drive signals for flowmeters having curved and straight flow tube geometries. The booster amplifier includes offline switching power circuitry (303) which operates on a plurality of standard AC voltages. The booster amplifier combines environmentally innocuous housing and barrier circuitry (300) to meet numerous regulatory agency safety standards for operating environments including explosive environments and increase the ease of installation and service of the booster amplifier.

摘要： A system for calibrating a drive signal applied to a driver affixed to a conduit to cause the driver to apply a force that vibrates the conduit in a desired mode of vibration. The calibration is completed by first developing a mathematical model of the apparatus and then using the model to mathematically calculate a proper drive signal voltage. The development of a model of the dynamics and calculation of the drive signal voltage are completed by vibrating the conduit, measuring the vibrations of the conduit, detecting physical characteristics of the apparatus from the measured vibrations, and determining a drive signal that causes the driver to oscillate the conduit in a desired mode of vibration responsive to determining the physical characteristics of the apparatus.

摘要： A single tube Coriolis flowmeter having a flow tube (901) and balance bar (902) vibrated in-phase opposition. Material flow through the vibrating flow tube induces Coriolis deflections in the flow tube which, via brace bars (913), induces in-phase Coriolis like deflection in the balance bar. A balance bar resonator (908) coupled to the balance bar is excited to vibrate in a rotational mode out of phase with respect to the balance bar. The vibration of the balance bar resonator increases the accuracy of the flowmeter output data by 1) increasing meter flow sensitivity by applying torque to the balance bar to reduce its in-phase Coriolis like deflections; 2) by applying torque to the flow tube via the balance bar to reduce shaking of the flowmeter; and 3) causing the flowmeter to have a flat calibration factor with respect to changed in material density by the provision of: apparatus (913) that changes the vibrational amplitude ratio of the flow tube and the balance bar in response to said detection of a change in material density; apparatus (909, 913) that changes the material flow sensitivity of the Coriolis flowmeter in a first direction in response to a change in vibrational amplitude ratio: apparatus (909) that alters the vibrational amplitude of the balance bar resonator to change the material flow sensitivity in a second direction in response to a change in resonant frequency; the changes in flow sensitivity in the first direction and in the second direction are effective to achieve a flow calibration factor of the Coriolis flow meter.

摘要： Method and apparatus defining bi-metallic process connections for a Coriolis flowmeter that are metallurgically bonded to form a sealed structure without the use of an O-ring or other elastomeric seal. The process connections comprise a first metal metallurgically bonded to a dissimilar metal to form a sealed process connection. The bond between the first metal and the dissimilar metal is outside the process material pathway so that the process connections in conjunction with the flowmeter form a flow path enclosed by a single metal.

摘要： A process parameter associated with a material contained in a conduit is estimated by estimating a real normal modal residual flexibility component associated with a real normal mode of motion of the conduit. A plurality of motion signals representing motion of the conduit is received. A residual-flexibility-compensated estimate of mass flow is generated from the received plurality of motion signals and the estimated real normal modal residual flexibility component.

摘要： An oscillatory vibration driver (104) is operably connected to a Coriolis flowmeter (10) for use in vibrating the meter flow tubes (103A and 103B). The meter electronics (20) contain a mimetic circuit (414, 802, 902) that permits use of the driver as a signal pickoff which provides a measurement of back electromotive force for use in calculating mass flow rate and density from the Coriolis flowmeter. The mimetic circuit contains an analog coil (604) and magnet (600) that facilitate the measurement of back electromotive force, or the mimetic circuit may comprise digital means (804, 806, 808, 904, 906).

摘要： An optimized Coriolis mass flow meter (140) is disclosed which comprises a pair of sensor means (118), each of said pair being mounted opposite the other on the sides of a flow conduit (112) for monitoring the oscillatory motion of said conduit (112). In order to improve stability to excitations caused by external influences and to maximize sensitivity, each sensor means is mounted as close as possible to two proximate nodes of a pair of vibration modes for the conduit (112). These modes are selected from among defined modes on the basis of a modal analysis to locate the nodes for each mode.
