Abstract: A piezoelectric fluid pressure fluctuation frequency sensor, preferably for a vortex-shedding flowmeter. A piezoelectric transducer is located in a sensor chamber between and in physical contact with a diaphragm and a chamber surface. Pressure fluctuations in a von Karman vortex street outside the diaphragm compress the transducer, between the diaphragm and the chamber surface. The transducer generates a responsive electrical signal which is representative of the pressure fluctuations.

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 process fluid flow device includes process communication circuitry, a processor, and measurement circuitry. The process communication circuitry is configured to communicate with at least one additional process device. The processor is coupled to the process communication circuitry and is configured to execute instructions to provide a plurality of cycles, wherein each cycle includes a number of flow-related calculations. Measurement circuitry is operably coupleable to a plurality of process variable sensors to obtain an indication of differential pressure during each cycle, and to obtain static pressure, and process fluid temperature. The processor is configured to compute a process fluid flow value using a current differential pressure sensor indication and at least one flow-related value calculated during a previous cycle. The process communication circuitry communicates the computed process fluid flow value to the at least one additional process device.

Abstract: A transmitter in a process control system for measuring flow rate measures total pressure (P.sub.TOT) and differential pressure (h) of process fluid flowing through a process pipe. The static pressure (P.sub.STAT) is determined based upon the total pressure (P.sub.TOT). The calculated static pressure is used to determine the fluid density (.rho.) and the gas expansion factor (Y.sub.1) of the process fluid flowing in the pipe. This information is used to calculate flow rate (Q) of the process fluid.

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.
