摘要： Method and apparatus (121) for providing temperature flow rate compensation for a Coriolis flow meter. The described compensation compensates both flow calibration factor and the nominal time delay, commonly called “zero” in the art. After a Coriolis flow meter is installed into a process, whether for calibration or for actual process use, it need only be zeroed once over its lifetime following its installation. This is a significant improvement over prior Coriolis flow meters that may need to be re-zeroed after minor changes in pressure, temperature, or installation.

摘要： The present invention relates to an apparatus for measuring a mass flow of a fluent material using the Coriolis measuring principle. The apparatus comprises an inlet tube positioned and configured to allow the fluent material to flow therethrough and into the apparatus. An impeller wheel rotates about a rotational axis. A motor is operatively connected to the impeller wheel and rotates the impeller about the rotational axis thereof. The impeller wheel is positioned with respect to the inlet tube such that the fluent material flowing through the inlet tube into the apparatus flows into a central area of the impeller. The impeller has vanes that redirect the fluent material flowing from the inlet tube into the central area of the impeller in a generally radial direction away from the central area as the impeller is being rotated by the motor. A flow distributing device associated with the inlet tube is constructed and arranged to distribute the fluent material flowing through the inlet tube towards the central area of the impeller generally symmetrically about the rotational axis of the impeller. A waste eliminating ring is positioned between the inlet tube and the impeller. The waste eliminating ring prevents loss of the fluent material deflecting off the impeller back towards the inlet tube. A frusto-conical flange is positioned about the impeller. A spherical compliant bearing is connected to the impeller and resists radial movement of the impeller. A force transducer is operatively associated with the impeller and a flexible connecting element extending between the stator of the motor and the force transducer such that the connecting element transmits rotational movement of the stator to the force transducer.

摘要： A system for measuring bidirectional flow, including backflow, of fluid in a conduit. The system utilizes a structural mechanism to create a pressure differential in the conduit. Pressure sensors are positioned upstream from the mechanism, at the mechanism, and downstream from the mechanism. Data from the pressure sensors are transmitted to a microprocessor or computer, and pressure differential detected between the pressure sensors is then used to calculate the backflow. Control signals may then be generated by the microprocessor or computer to shut off valves located in the conduit, upon the occurrence of backflow, or to control flow, total material dispersed, etc. in the conduit.

摘要： A system for measuring fluid flow in a conduit having a gradual bend or arc, and a straight section. The system includes pressure transducers, one or more disposed in the conduit on the outside of the arc, and one disposed in the conduit in a straight section thereof. The pressure transducers measure the pressure of fluid in the conduit at the locations of the pressure transducers and this information is used by a computational device to calculate fluid flow rate in the conduit. For multi-phase fluid, the density of the fluid is measured by another pair of pressure transducers, one of which is located in the conduit elevationally above the other. The computation device then uses the density measurement along with the fluid pressure measurements, to calculate fluid flow.

摘要： Apparatus and method for metering the flow rate of a fluid through a conduit in which a low inertia transducer is placed between the inlet and outlet, the transducer having a substantially cylindrical housing and a rotatable element concentric to the housing which together define an arcuate pathway for the flow of the fluid. A pressure sensor generates a pressure error signal corresponding to a change in pressure between the inlet and outlet and translates the same into a detectable signal which is used to change the speed of the rotatable element to reduce the differential pressure between the inlet and outlet.
