Abstract: A method of providing configuration information for a process fluid flow device is provided. The method includes receiving a process fluid selection and providing at least one selectable fluid property relative to the selected process fluid and receiving at least one process fluid property selection. Information relative to a primary element is also received. Reception of a reset relative to the process fluid selection, the process fluid property, and the primary element selection, clears the respective information. The configuration information is provided to a process fluid flow device based on the process fluid selection, the process fluid property and the primary element information.

Abstract: A process variable transmitter with diagnostics based on power spectral density (PSD) analysis of a process variable sensor signal is provided. In one embodiment, the process variable transmitter is a pressure transmitter and the diagnostics are used to diagnose impulse line obstruction or impending obstruction. Other diagnostics are also useful such as diagnosing primary element degradation. The sensor signal is digitized and the digitized signal is transferred into the frequency domain. The power of the frequencies on the sensor signal is examined to provide the enhanced diagnostics. In one aspect diagnostics are generated directly with the sensor PSD data. In another aspect, the PSD analysis is used to tune a filter in order to enhance traditional diagnostic algorithms.

Abstract: A pressure transmitter produces signals indicative of a flow in a pipe. The transmitter has a pressure sensor that is fluidly coupled to two ports in the pipe, and the pipe has a substantially constant cross-section between the two ports. Aspects of the invention include a circuit coupled to the pressure sensor that produces a digital value related to the fluid flow as a function of the pressure difference between the two ports.

Abstract: A vortex-shedding flowmeter comprising two stationary vortex-shedding cross-members (i.e., bluff bodies) disposed transversely to a stream of fluid. Each cross-member has a bluff face with sharp Karman vortex generating edges with independently selected edge to edge widths d of from 10 to 40% of the inside width of the conduit through which the fluid flows and lengths 1 of from 0.3 to 2.0d. The second cross-member is disposed downstream of the first cross-member a distance of from 4 to 15 times the width d of the first cross-member. Any sensor may be used in any location provided it or they sense the Karman vortices generated by co-action of the two cross-members. This flowmeter provides strong signals with a high signal to noise ratio and high Strouhal number.

Abstract: A system and method for controlling at least one hydraulic actuator of a hydraulic system includes a flow rate measurement of a hydraulic fluid flow traveling into and out of a cavity of the hydraulic actuator. The flow rate is used to calculate piston information corresponding to a position, velocity, acceleration, and/or direction of movement of a piston of the hydraulic actuator. The piston information can then be provided to an output device to aid in the control of the hydraulic actuator. Alternatively, the piston information can be compared to a reference signal relating to a desired position, velocity, acceleration, and/or direction of movement of the piston to produce a control signal, which can be used to adjust the hydraulic fluid flow and provide the desired actuation of the piston.

Abstract: An improved flow meter and sensor body therefor, the body having a strain relief portion. A housing of the flow meter defines a fluid flow passage and a sensor body opening. A sensor body mounting portion is mounted to the housing. A sensor body sensor supporting portion is in the fluid flow passage, and supports flow sensor transducers in the fluid flow. The sensor body relief portion is intermediate the sensor body mounting and supporting portions, in the sensor body opening, and adapted to relieve induced strain from external vibration, whereby the flow meter is substantially insensitive to external vibration.

Abstract: A pneumatic process controller includes a nozzle mounted on a set point lever and a flapper with a connected process lever. The set point lever pivots the nozzle about a set point and input axis in response to set point adjustment. The process lever pivots the flapper about the same axis in response to the process variable. The nozzle and set point lever are mechanically separated from the flapper and process lever. Artificial effect upon the process variable from set point adjustment is eliminated.
