The local application includes a host computer. The remote application includes a plurality of field devices and a communication bus connected to the plurality of field devices. Packet messages are wirelessly communicated between the local application and the remote application such that the host computer and field devices can communicate with each other as if they were directly connected to the same communication bus.

Abstract: A process control instrument for coupling to a process is attachable to a metal flange. The flange has a first passageway adapted to be filled with process fluid. The process control instrument includes a body having an opening adjacent to the first passageway for receiving process fluid from the first passageway when the process control instrument is attached to the flange. A diaphragm is disposed across the opening for fluid communication with the process fluid. A seal is positionable against the flange to prevent process fluid from leaking past the flange and diaphragm. The seal includes a ring positioned in the opening and coupled to the body, the ring being substantially in contact with the diaphragm along an inner annular shoulder when the body is not attached to the flange (unloaded).

Abstract: A manufacturing procedure of a vortex flowmeter is disclosed that allows for assembly of a vortex sensor assembly with one of two or more unitary flowtubes that have bores that are smaller than the flowtube flanges in two or more size number steps. The unitary flowtubes include flanges, flowtube bores and expanders (also called reducers) that provide a smooth flow transition from the larger flanges to the smaller bores.

Abstract: A diaphragm diagnostic system for use in an industrial field device has a diaphragm and a diagnostic feature. The diaphragm is configured to couple the field device to a process fluid and has a plurality of layers. A first layer of the plurality of layers is exposed to process fluid of an industrial process. A diagnostic feature is coupled to the diaphragm to monitor an electrical parameter of the diaphragm and responsively infer an operative state of the diaphragm based on a change in the monitored electrical parameter.

Abstract: The system has a control center, a time master device and a plurality of distributed, time slave field devices in synchronization with a master clock of the time master device. The time master device periodically transmits a time distribution data unit. Each time slave field device has a timer adjustment element, a fixed rate clock and a variable clock. The timer adjustment element calculates a frequency ratio between the master clock and the fixed rate clock and uses the frequency ratio to calculate adjustment coefficients to adjust a local sense of time for each field device, such that a time stamp of each field device is synchronized to the master clock.
