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.
