摘要： A vibratory meter (5, 1600) configured to predict and reduce noise in the vibratory meter (5, 1600). The vibratory meter (5, 1600) includes a sensor assembly (10, 1610) and a meter electronics (20, 1620) in communication with the sensor assembly (10, 1610). The meter electronics (20, 1620) is configured to provide a drive signal to a sensor assembly (10, 1610), receive a sensor signal from the sensor assembly (10, 1610) having one or more components, and generate a signal to be applied to one of the sensor signal and the drive signal to compensate for the one or more components.

摘要： A method of measuring fluid flow in a system includes providing a fluid supply assembly which includes a fluid supply supplying fluid, a dispensing valve from which the fluid is dispensed, a dispensing line connecting the fluid supply to the dispensing valve, a gear pump including a motor and a gear being rotated by the motor to provide a flow of fluid from the fluid supply to the dispensing line, a revolution counter counting a number of revolutions of an element of the gear pump, a pressure transducer coupled to the dispensing line sensing pressure in the system, and a controller including a processor and a memory to control the system. The method further includes directing fluid from the fluid supply, rotating the gear to provide the flow of fluid from the fluid supply to the dispensing line, and providing a calibration process by modulating the gear pump.

摘要： A system for identifying an anomaly in flow meter proving equipment includes four detectors D1, D2, D3, and D4. A data acquisition and monitoring system is configured to signals from D1, D2, D3, and D4 to measure flow volumes between D1 and D3 as a measured volume Va, between D2 and D4 as a measured volume Vb, between D2 and D3 as a measured volume Vc, and between D1 and D4 as a measured volume Vd. The data acquisition and monitoring system calculates Va+Vb−Vc−Vd plus a max uncertainty as an upper range value and Va+Vb−Vc−Vd minus the max uncertainty as a lower range value. The data acquisition and monitoring system identifies an anomaly in response to the upper range value being less than zero or the lower range value being greater than zero and initiates recalibration of the prover in response to the identifying of the anomaly.

摘要： Embodiments of a portable verification system can move from one in-field gas flow meter location to another and temporarily connect downstream of a main pipeline's meter run or station. A control valve of the portable verification system allows volume measurement at different flow velocities to be verified. In some embodiments, the portable verification system is connected to the meter run and the main pipeline by an adjustable pipeline section. This section can extend horizontally and vertically, as well as swivel to provide versatility when connecting in the field. Adaptor fittings having one flange sized for and fitted to the inlet and outlet ends of the portable verification system and another flange sized for the meter run or main pipeline connection provide additional versatility. Downtime is limited to the time required to complete a circuit between the meter run, portable verification system, and main pipeline.

摘要： In one aspect, data characterizing a fuel storage facility can be received from a sensor in operable communication with the fuel storage facility. An estimate of meter drift of a flow meter of a fuel dispenser in fluid communication with the fuel storage facility can be determined based on the received data. The estimate of meter drift can be determined based on at least one predictive model that predicts whether a calibration parameter characterizing a calibration of the flow meter has deviated from a predetermined flow meter calibration parameter. The estimate of meter drift can be provided.

摘要： The present disclosure relates to a magnetic-inductive flowmeter for measuring flow velocity of a medium, comprising a measuring tube; an apparatus positioned toward a cross-section of the measuring tube for producing a magnetic field extending perpendicular to a longitudinal direction, wherein the apparatus includes a segment coupling the magnetic field into the medium, wherein the segment surrounds the measuring tube over a first angle; and an electrode system having at least two electrode pairs adapted to register a voltage induced in the medium, wherein a second angle defines a minimum circular sector in which the electrodes located on one side of the measuring tube are distributed, wherein first and second angles are so matched to one another that the flowmeter is insensitive to departures from a rotationally symmetric flow such that the flowmeter in a test measurement has a measurement error of flow velocity less than 1.0%.

摘要： A multiphase flow calibration semi-closed loop system includes an oil-gas-water separation unit, a multiphase flow calibration unit, a single phase flow calibration section, a gas flow section, a flow data acquisition unit, and a programmable logic controller (PLC). The system is designed to have a two-step calibration process. In a first step, single phase water flow meters and single phase oil flow meters of the system are calibrated independently. In a second step, multiphase flow meters or multiphase water cut meters are calibrated using the pre-calibrated water flow meter, pre-calibrated oil flow meter, and the pre-calibrated gas flow meter. In doing so, the oil-gas-water separation unit, the multiphase flow calibration unit, the single phase flow calibration section, and the gas flow section communicate with the flow data acquisition unit providing real time data. Thus, the PLC connected to the flow data acquisition unit can perform the required calibration processes.

摘要： A gases humidification system includes a measuring chamber and a mixing chamber. The mixing chamber has one or more mixing elements that improve a mixing of gases before reaching the measuring chamber. Ultrasonic sensing is used to measure gases properties or characteristics within the measuring chamber. A baffle or a vane may be used to control and direct the gases flow through the mixing chamber as the gases flow moves into the measuring chamber.
