摘要： A fault detection device includes a wastegate valve, a control unit, a working gas amount computation section, and a determination section. The control unit obtains a rotational speed of an engine, a boost pressure, and an intake air temperature. The working gas amount computation section computes a computed value of a mass flow rate of working gas in the engine by using the rotational speed, the boost pressure, and the intake air temperature. The determination section determines that the wastegate valve has a fault when the computed value is not a normal value.

摘要： A conveyor mechanism conveys a powder along a path. A first camera device arranged above the conveyor mechanism detects movement of a recognizable feature on an upper surface of the powder over a period of time. A velocity of the powder can be determined based on the movement of the recognizable feature over the period of time. A device can be used to generate the recognizable feature. A first light-emitting device can illuminate the upper surface to aid detection of the recognizable feature. A second light-emitting device can project a contour line on the upper surface, and a second camera device can be used to detect a position of the contour line. A cross sectional area of the powder can be correlated based on the position of the contour line.

摘要： An agricultural implement system is provided including a fluid conduit configured to provide product to a ground engaging tool. The ground engaging tool is configured to deposit the product into soil. The agricultural implement system also includes an air source fluidly coupled to the fluid conduit, and configured to provide an air flow through the fluid conduit in a downstream direction toward the ground engaging tool. The agricultural implement system further includes a product delivery system fluidly coupled to the fluid conduit, and configured to transfer the product into the air flow. In addition, the agricultural implement system includes a product flow measurement system configured to determine a mass flow rate of the product based on a pressure drop between an upstream portion of the fluid conduit and a downstream portion of the fluid conduit, a flow rate of the air flow, and a velocity of the air flow.

摘要： Two-wire transmitters are described in which the required voltage that a control room must supply to the transmitter is lower at high current than at low current, thus freeing up more voltage for other uses, and in which a constant set of operating voltages may be maintained. A corrected pressure in a vortex flow meter may be determined that reflects the mass flow rate. Thus, the mass flow rate may be determined based on the corrected pressure reading and a measured volumetric flow rate. Density may be determined from pressure and temperature using a table containing error values based on a standard density determination and a relatively simple approximation. During operation of a flow meter, the stored error values may be linearly interpolated and the approximation may be computed to determine the density from the stored error value.

摘要： A method of measuring a molecular rate of gas flow from an upstream source of gas at a pressure higher than a pressure of a destination includes flowing the gas through an upstream valve into a cavity of known volume, then through a restrictor element before proceeding to the destination, controlling the upstream valve to vary a flow rate of the gas through the upstream valve in a determined manner such that its average pressure in the cavity correlates with an average level of gas flow and such that variations in pressure in the cavity induced by varying the flow rate of gas through the upstream valve in the determined manner induce instantaneous pressure variations smaller than 30% of the average pressure in that cavity; and using the variations in the pressure in the cavity associated with varying the flow rate of gas through the upstream valve in the determined manner to determine the molecular rate of gas flow to the destination in real time.

摘要： A processor module features a module that respond to input signalling containing information about a volumetric flow of a fluid having minerals and varying amounts of entrained gas flowing in a pipe and being processed in a processing stage of a mineral extraction processing system for extracting a mineral from ore, and provides output signalling containing information about operations of the processing stage of the mineral extraction processing system that is not substantially affected by the varying amounts of entrained gas in the fluid flowing in the pipe. The output signalling controls the operations of the processing stage. The input signalling is based upon a speed of sound measurement, including a SONAR-based entrained gas measurement to determine the amount of entrained air in conjunction with a density measurement of the fluid flowing in the pipe.
