摘要： A method to calibrate a flow meter includes passing a predetermined volume of fluid through a flow meter for calibration and determining a time duration of calibration from a start time to a stop time. One or more characteristics of the flow rate of the fluid is measured with the flow meter during the time duration and a plurality of time stamped measurements based on the one or more measured flow rate characteristics are generated. The flow meter is then calibrated based on the start time, the stop time, and the plurality of time stamped measurements.

摘要： A method for determining a velocity of a flowing fluid includes estimating a Reynolds number for the flowing fluid; comparing the estimated Reynolds number with a selected range; and determining the velocity of the flowing fluid based on a flow model selected from a laminar flow model, a turbulent flow model, and a partial laminar flow model. An ultrasonic flow meter includes a plurality pairs of transducers configured to form a plurality of measurement paths in a pipe, wherein the plurality of measurement paths are arranged asymmetrically relative to a centerline of the pipe.
