Abstract: A plug-and-play sensor peripheral component includes an electrically conductive physical connector; an electrical connector; a transformer; and an RF communication and data storage circuit. The electrical connector is electrically connected to the physical connector by a first conductive path. The transformer is electrically connected to the RF communication and data storage circuit. The transformer and the RF communication and data storage circuit are electrically isolated from the physical connector and the electrical connector. Electrically connecting the physical connector to the electrical connector by other than the first conductive path inductively couples the RF communication and data storage circuit to the first conductive path.

Abstract: A magnetic flowmeter comprises a pipe section for process flow, a coil for generating a magnetic field across the pipe section, a current source for energizing the coil to generate the magnetic field at a coil drive frequency, and electrodes for sensing voltage induced across the process flow by the magnetic field. A processor calculates a function of the sensed voltage and generates a flow output based on the function. The processor adjusts an operating parameter of the flowmeter, such as electrode voltage sampling period, the coil drive frequency, or a phase shift, as a function of a sensed electrode-to-electrode or electrode-to-ground complex impedance.

Abstract: A field device resident algorithm receives one or more diagnostic inputs and generates actionable service information. The algorithm(s) can be changed or updated after the manufacture of the field device. The actionable service information can be displayed locally or sent over a process control loop. A prediction engine can be employed to determine a period within which such service should be completed.

Abstract: A system for measuring and analyzing radio frequency power proximate and within a wireless field device mesh network. A centralized software module (CSWM) collects and analyzes values from one or more wireless devices of the wireless field device mesh network representing received RF power measurements on an assigned RF channel and values representing corresponding times of the received RF power measurements. Each wireless device measures received RF power on the assigned RF channel at times other than during reception of a signal resulting in transmission by the wireless device of either an acknowledgment signal or a non-acknowledgement signal. Values representing the received RF power measurements and the corresponding times of the received RF power measurements are determined from the stored received RF power measurements and corresponding times and then discarded. These values are stored within the wireless device until successfully reported. A network manager coordinates communication between the wireless devices and synchronizes the corresponding times of received RF power measurement throughout the wireless field device mesh network.

Abstract: A viscometer comprises a plurality of capillary tubes connected in series with a mass flow meter. The capillary tubes are smooth, straight, and unimpeded, and each has a different known, constant diameter. Differential pressure transducers sense differential pressure across measurement lengths of each capillary tube, and the mass flow meter senses fluid mass flow rate and fluid density. A data processor connected to the mass flow meter and the differential pressure transducers computes viscosity parameters of fluid flowing through the viscometer using non-Newtonian fluid models, based on the known, constant diameters and measurement lengths of each capillary tube, the sensed differential pressures across each measurement length, the fluid mass flow rate, and the fluid density.
