Abstract: A magnetic flowmeter includes at least one coil configured to generate a magnetic field within a process fluid flow. A pair of electrodes is configured to detect an electromotive force within the flowing process fluid in response to the magnetic field. Measurement circuitry is coupled to the pair of electrodes and is configured to provide an indication of the detected electromotive force. A processor is coupled to the measurement circuitry and configured to receive the indication of the detected electromotive force and determine a flow-related output based on the detected electromotive force. A diagnostics component is configured to analyze a number of successive parameters of the magnetic flowmeter in order to provide an indication of a detected entrained fluid.

Abstract: A magnetic flowmeter includes at least one coil configured to generate a magnetic field within a process fluid flow. A pair of electrodes is configured to detect an electromotive force within the process fluid flow in response to the magnetic field. Coil drive circuitry is coupled to the at least one coil and is configured to cause the at least one coil to generate the magnetic field. Measurement circuitry is operably coupled to the pair of electrodes and configured to provide an indication of the detected electromotive force. A processor is coupled to the measurement circuitry and the coil drive circuitry. The processor is configured to cause the coil drive circuitry to operate at one of a plurality of coil drive frequencies. The processor is also configured to obtain a plurality of measurement samples while process fluid is flowing and while the coil drive circuitry is operating at a first frequency. The processor is configured to generate an autozero estimate for operation at a second coil drive frequency higher than the first coil drive frequency and to save the autozero estimate for use during operation at the second coil drive frequency.

Abstract: A magnetic flow meter includes electrode sensors generating a sensor signal indicative of flow of a liquid through a conduit. A noise identification module identifies a noise level in the sensor signal and a contaminant identification module uses the noise level to determine whether there is a contaminant in the liquid in the conduit.

Abstract: Vibratory meters (5), and methods for their use measuring a fluid are provided. Each vibratory meter includes a multichannel flow tube (300) comprising two or more fluid channels (302), a pickoff (170), a driver (180), and meter electronics (20) configured to apply a drive signal to the driver at a drive frequency ω, and measure a deflection of the multichannel flow tube with the pickoff. In examples, at least one fluid channel has an effective diameter that is related to kinematic viscosity, inverse Stokes number, and drive frequency. In further examples, the driver may apply a drive signal to the driver having a drive frequency proportional to the kinematic viscosity, inverse Stokes number, and effective diameter.

Abstract: A vortex flowmeter includes a housing having an interior cavity, a vortex shedder supported by the housing and extending into the interior cavity, an ultrasonic sensor, a bending moment sensor and a controller. The ultrasonic sensor is configured to produce an ultrasonic flow rate output that is indicative of the flow rate of a fluid flow through the interior cavity. The bending moment sensor is configured to produce a bending moment flow rate output that is indicative of the flow rate of the fluid flow through the interior cavity. The controller is configured to generate a flow rate measurement that is indicative of the flow rate based on the ultrasonic flow rate output and/or the bending moment flow rate output.

Abstract: A method for calibrating a flowmeter (5) transducer is provided comprising the steps of exciting a vibration mode of a flowmeter (5) flow tube (130, 130′) and ceasing to excite the vibration mode, wherein a free decay response of the flow tube (130, 130′) is measured. Amplitudes and phases of the free decay response at a drive frequency are extracted, and a strength of the transducer is calculated.
