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: A process variable transmitter is configured as a flowmeter for measuring flow of a process fluid through a conduit. The transmitter includes a pitot tube extending into the conduit which creates a differential pressure in the process fluid due to flow of the process fluid. An upstream process variable sensor is mounted on the pitot tube and coupled to the flow of process fluid to sense an upstream process variable of the process fluid. A downstream process variable sensor is mounted on the pitot tube downstream of the upstream process variable sensor and coupled to the flow of process fluid to sense a downstream process variable of the process fluid. Measurement circuitry determines the flow of the process fluid based upon the upstream process variable and the downstream process variable.
