Abstract: A system for measuring concentration of water vapor in a gas includes a pressure sensor configured to sense a static pressure of the gas and a differential pressure sensor configured to sense a differential pressure. A temperature sensor senses a temperature of the gas. Circuitry estimates determines a concentration of water vapor in the gas based upon the measured pressures and temperature.

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: During manufacturing a unique encrypted authentication code is created for each product based upon device specific information relating to that product. The unique encrypted authentication code together with the device specific information is stored in a database, and a representation of the unique encrypted authentication code is stored on the product. To determine whether a product in question is authentic, the readable representation of the unique encrypted authentication code is read and sent to a server along with a request for product authentication. The server provides an indication of authenticity of the product in question based upon the unique encrypted authentication code received and the device specific information associated with that unique encrypted authentication code in the database.

Abstract: A system comprises a differential pressure sensor, a process pressure sensor, a temperature sensor and a microprocessor. The differential pressure sensor is positioned to sense differential pressure along a fluid flow, where fluid properties of the fluid flow have first and second phases separated along a transition curve. The process pressure sensor is positioned to sense a pressure of the fluid flow, and the temperature sensor is positioned to sense a temperature of the fluid flow. The microprocessor is coupled to the temperature sensor and the pressure sensor to determine a flow rate, and the microprocessor generates a diagnostic based on the process pressure and the temperature as compared to the transition curve.

Abstract: Methods and systems for assessing transmitter electronics in an industrial process control system comprise generating a process condition reference equation signal, a process condition approximation equation signal, and an accuracy output signal. The process condition reference equation signal is generated using a process condition reference equation and process control inputs. The process condition approximation equation signal is generated using a process condition approximation equation that approximates the reference equation using the process control inputs, and approximation equation coefficients based on the approximation equation and the process control inputs. The approximation equation signal is compared to the reference equation signal at a control room workstation such that the industrial process control system can be adjusted. In one embodiment, the approximation equation coefficients are adjusted and transmitted to process transmitter electronics over a control network.
