A system and method for ultrasonic flow metering. In one embodiment, an ultrasonic flow metering system includes a passage for fluid flow and a plurality of ultrasonic flowmeters. Each of the ultrasonic flowmeters includes a pair of ultrasonic transducers, and a flow processor. The pair of ultrasonic transducers is configured to form a chordal path across the passage between the transducers. The flow processor is coupled to the ultrasonic transducers. The flow processor is configured to measure the fluid flow through the spool piece based on outputs of the transducers of all of the ultrasonic flowmeters.

System and method for combining co-located flowmeters

A system and method for ultrasonic flow metering. In one embodiment, an ultrasonic flow metering system includes a plurality of ultrasonic flowmeters. Each of the ultrasonic flowmeters includes a flow processor. The flow processor is configured to maintain a plurality of velocity bins, each of the bins corresponding to a flow velocity range for the flowmeters. The flow processor is also configured to maintain, within each of the bins, a value indicative of past average velocity of fluid flow through a given one of the flowmeters associated with a given one of the bins. The flow processor is further configured to determine, responsive to one of the flowmeters having failed, an estimated average fluid flow velocity through the system based on the values maintained within the bins.

System and method for meter substitution for co-located flowmeters

Flow meter validation techniques are herein disclosed. An illustrative system includes a flow meter and display logic coupled to the flow meter. The flow meter is configured to provide information indicative of a parameter of fluid flow through the meter. The display logic is configured to provide a display of the information. The display includes an indication of a possible range of values of the parameter. An indication of a baseline portion of the range is also provided. The baseline portion of the range designates preferred values of the parameter. The display further includes an indicator designating the value of the parameter.
