摘要： A flow rate sensing device in which electrodes are concentrically disposed so as to form an electric field having a field strength which changes in space along the flow of a dielectric fluid, and a current sensing means measures the dielectric polarization-current produced when the dielectric fluid flows in the electric field. This device senses a highly changing flow rate, e.g., an intermittent flow, with good response and is therefore suitable for measuring the flow rate of a fuel.

摘要： A net oil and gas well test system for a set of oil and gas wells includes at least two net oil and gas measurement systems and a plurality of valves that are in fluid communication with the individual wells in the set and independently configurable between a first state, in which the valve routes flow to a first net oil and gas measurement system, and a second state, in which the valve routes flow to a second net oil and gas measurement system. Each net oil and gas measurement system suitably has the capability to measure a multiphase flow including oil, gas, and water without separation. For example, each measurement system can include a multiphase Coriolis meter and a water cut meter. Each measurement system suitably includes the capability to provide dynamic uncertainty estimates related to measurement of the multiphase flow.

摘要： A multi-phase fluid is passed through a Coriolis flowmeter and a watercut meter. The multi-phase fluid includes two phases during a first time period and three phases during a second time period. It is determined that the multi-phase fluid includes two phases during the first time period, and a first value of a parameter of the multi-phase fluid is determined using a value measured by the Coriolis flowmeter during the first time period. A second value of a parameter of the multi-phase fluid is determined using a value measured by the watercut meter during the first time period. The first value is compared to the second value, and it is determined, based on the comparison, that the first value and the second value are inconsistent with each other.

摘要： A mass flow meter (10, 50, 130, 200, 300) comprising a housing (11) including a fluid inlet (4) and a fluid outlet (6, 36). The housing (11) defines a chamber (13) and a rotatable member (12A, 12B, 60A, 60B, 210A, 210B) is arranged in the chamber (13) so as to be rotatable about an axis (24). A momentum device (14, 15) is also arranged in the chamber (13) and connected to the rotatable member (12A, 12B, 60A, 60B, 210A, 210B) via a connection comprising a biasing element (9, 52) so as to be rotatable about the axis (24) and rotatable relative to the rotatable member (12A, 12B, 60A, 60B, 210A, 210B). A fluid path (34) in fluid communication with the fluid inlet (4) and the fluid outlet (6, 36) is provided. The fluid path (34) passes through both the rotatable member (12A, 12B, 60A, 60B, 210A, 210B) and the momentum device (14, 15). The fluid path (34) enters the momentum device (14, 15) at a radial distance r1 from the axis (24) and exits the momentum device (14, 15) at a different radial distance r2 from the axis (24). A torque provider (21, 56) may be coupled to the rotatable member (12A, 12B, 60A, 60B, 210A, 210B) via a shaft (8, 62) or gear member (58).

摘要： A force balanced mass flow meter is disclosed that includes a cylindrical sensor housing having an interior bore, an impeller body supported for axial rotation within the interior bore of the sensor housing , and including structure for converting fluid inertia into flow induced torque when fluid flows relative to the impeller body, a proximity sensor for measuring a rotation angle of the impeller body relative to the sensor housing, an electromagnet for generating a magnetic field about the sensor housing to prevent rotation of the impeller body, electronics for determining electrical values from the proximity sensor when fluid flows relative to the impeller body and a controller for controlling current supplied to the electromagnet in response to electrical values determined from the proximity sensor, to generate a magnetic field sufficient to prevent impeller rotation.
