    Abstract: A flow control system comprises a flow sensor, a valve controller, a signal processor, a control processor and an interface. The flow sensor generates a sensor signal characterizing a flow rate. The valve controller controls the flow rate as a function of a control output. The signal processor converts the sensor signal into a flow signal characterizing the flow rate as a function of time, and the control processor generates the control output as a function of a setpoint and the flow signals. The interface receives an input representative of the setpoint, transmits a flow output representative of the flow signals, and transmits a diagnostic output directly indicative of an operational condition of the flow control system.

    Abstract: A process variable transmitter for use with a removable operator interface has a non-volatile memory and a latching component. The non-volatile memory stores device settings. The latching component prohibits changes to transmitter settings if the removable operator interface is absent. Circuitry in the transmitter detects the presence of the removable operator interface. The removable operator interface can include zero and span settings.

    Abstract: A Safety Instrumented System for use with a process control system receives pressure of process fluid in the process piping. A valve positioner positions a valve which controls flow of process fluid through the process piping. The valve positioner is caused to perform a partial stroke of the valve or otherwise introduce a perturbation into the process. A resulting change in sensed pressure due to the perturbation is used to diagnose operation of the process.

    Abstract: A process variable transmitter for measuring a process variable of a process fluid in a vessel includes first and second pressure couplings arranged to receive a first pressure and a second pressure of process fluid in the vessel. These pressures are related to the density of the process fluid. A sensor provides a sensor output related to the process fluid in the vessel. Measurement circuitry is configured to calculate a calculated process variable of the process fluid in the vessel based upon the first and second pressures and the sensed process variable.

    Abstract: A remote seal assembly includes a seal body and an extension. The seal body defines a cavity with a diaphragm that seals the cavity from a process fluid. The extension is connected with the seal body on a first end and is configured for connection to a capillary tube on a second end. The extension defines a bore extending from the first end to the second end that is fluidically coupled to the cavity. A length of the extension is related to a temperature of the second end of the extension such that the second end of the extension is at or below an outgassing temperature of the material used to connect the extension and the capillary tube.
