Abstract: A system and method for measuring a flow of saturated steam can include a temperature sensor that measures process temperature, and one or more pressure sensors that measure pressure including differential pressure and static pressure. A flow of saturated steam can be calculated from two sets of measurements, one measurement using the differential pressure and the static pressure and a second measurement using the differential pressure and the process temperature. Redundant flow measurements can be provided with respect to the flow of saturated steam in case of failure of the temperature sensor or the pressure sensors. In addition, a deviation between the flow of the saturated steam as calculated from the process temperature and the differential pressure compared to a flow of saturated steam as calculated from the differential pressure and the static pressure can provide an indication of degradation of the temperature sensor or the pressure sensors.

Abstract: A tamper-resistant cover apparatus includes a cover securable to the front face of a peripheral device. Such a cover permits status indicators and power buttons on the front face of the peripheral device to be visible through the cover and wherein the cover is attached to the face of the peripheral device by one or more connecting components to prevent unintended or malicious changes to the peripheral device. One or more portions of the cover can define an open area through which one or more electronic cables connect to one or more ports of the peripheral device. The open area supports the presence of electronic cables while preventing the electronic cable(s) from being removed as well as preventing unused ports from being accessed while the cover is in place.

Abstract: A fluid level transmitter combination for placement on a tank having ?2 tank apertures. A first and second flange provides a first, second and third flange aperture over the tank aperture(s). A temperature sensor over the first flange aperture senses a temperature. A first pressure sensor over the second flange aperture senses a first pressure. A second pressure sensor senses a second pressure. A processor is coupled to the output of the second pressure sensor that implements a compensated fluid level determination algorithm using the temperature, first pressure, and second pressure to generate a compensated fluid level measurement for the process fluid. A transmitter is coupled to an output of the processor.
