Abstract: A pressure transmitter (10) with a fluid isolator (11) that includes a sensor tube (38) and a fill tube (50) that have "D" shaped ends (40, 54) that connect together in a port (18) internal to the transmitter (10). The shaped ends (40, 54) can be brazed into the port (18) for sealing. Fitting both the sensor tube (38) and the fill tube (50) in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator (11) has an isolator diaphragm (96) with a central diaphragm region (100) overlying a central backing plate (94) that includes an annular groove (111). The annular groove (111) avoids slow response of the isolator (11) after an overpressure condition.

Abstract: A vortex sensor (11) senses generated vortices and provides a vortex signal. A filtering circuit (68) is coupled to the vortex sensor (11) to receive the vortex signal and provide an output indicative of fluid flow. A temperature sensor (82) senses a temperature of the fluid and provides a temperature value, while a pressure sensor (86) senses a pressure of the fluid and provides a pressure value. A processor (70, 70A) is operably coupled to the filtering circuit (68), the temperature sensor (82), and the pressure sensor (86) for receiving the output, the temperature value, and the pressure value, respectively. The processor (70, 70A) calculates a calibration factor as a function of the output, the temperature value, and the pressure value for use in calculating the output value indicative of the flow rate of the fluid.

Abstract: A process transmitter for measuring a process variable in an industrial process comprises a gauge pressure sensor, an excitation source and transmitter circuitry. The gauge pressure sensor measures a pressure difference between a process fluid and a reference volume, and generates a pressure sensor signal representing the pressure difference. The excitation source generates a pressure pulse within the reference volume to influence generation of the pressure sensor signal. The transmitter circuitry is connected to the gauge pressure sensor to provide an output related to a change in the pressure sensor signal due to the pressure pulse.

Abstract: A process transmitter (12) for sensing a process variable of a process fluid includes a process sensor (30), transmitter circuitry (40), a transmitter housing (38) and a transmitter mounting component (33, 44A, 44B). The process sensor (30) senses the process variable of the process fluid and the transmitter circuitry (40) processes a signal from the process sensor (30). The transmitter housing (38) receives the process sensor (30) and transmitter circuitry (40), and the transmitter mounting component (33, 44A, 44B) isolates the sensor (30) or the transmitter circuitry (40) from the process fluid or external environment. The mechanical integrity sensor (46A, 46B, 52A, 52B) validates assembly of the transmitter housing (38) and transmitter mounting component (33, 44A, 44B).
