Abstract: A vortex flowmeter includes a flow tube having a first end and a second end. A shedder bar is disposed within the flow tube between the first end and the second end. The shedder bar is configured to generate vortices in fluid flowing through the flow tube. At least one sensor is operably coupled to an external surface of the flow tube and is configured to detect individual deformations of the flow tube resulting from vortices inside the flow tube.

Abstract: A diagnostic field device for detecting a condition of a process conduit includes an infrared detector comprising a plurality of pixels configured to receive infrared radiation from the process conduit and responsively provide a plurality of pixel outputs. A first pixel of the plurality of pixels is configured to receive infrared radiation from a first location on the process conduit. A second pixel of the plurality of pixels is configured to receive infrared radiation from a second location on the process conduit. A memory contains thermal profile information which relates an output from the first pixel to a first temperature at the first location and relates an output from the second pixel to a second temperature at the second location. A microprocessor identifies a process anomaly based upon outputs from the first and second pixels. Output circuitry provides a diagnostic output indicative of the identified process anomaly.

Abstract: A steam quality meter includes a pipe with an inlet and an outlet. A rod is located within the pipe between the inlet and the outlet. The rod defines an annular flow passage between an outer wall of the rod and an inner wall of the pipe. A mixing device is located within the pipe between the inlet and an upstream end of the rod. Spaced sensors are located within the annular flow passage. Each sensor is configured to sense capacitance and/or impedance of steam flowing through the annular flow passage.

Abstract: A polymeric remote seal system is provided for coupling a single-use container to a pressure measurement instrument. The polymeric remote seal system includes a process-side coupling, an instrument-side coupling and a fluidic coupling therebetween. The process-side coupling is configured to couple to the single-use container and is formed of a radiation sterilizable polymer. The process-side coupling has a process-side deflectable diaphragm that is configured to deflect in response to pressure within the single-use container. The instrument-side coupling is configured to couple to the pressure measurement instrument and is formed of a radiation sterilizable polymer. The instrument-side coupling is configured to fluidically convey fluid pressure to an isolation diaphragm of the pressure measurement instrument. Tubing fluidically couples the process-side coupling to the instrument-side coupling.
