Abstract
A method and apparatus for measuring flow rates is disclosed. At least one of a non-vortex based low-flow measurement and a vortex based flow measurement is taken. The measurement or measurements are communicated to a central processor. The processor analyzes the data provided and makes a determination as to the more accurate measurement, if there is more than one measurement. The flow rate is calculated by the processor and is based on either the singular or the more accurate measurement. Further enhancements include diagnosis of meter performance, redundancy of measurements, and re-calibration of either measurement device based on information from the other device.
