Abstract
The present invention provides a method and apparatus for the measurement of a pressure differential across a differential pressure flow meter ΔPand the line pressure drop due to friction ΔPalong a length L of pipe. Subsequently, the quantity (formula) is calculated, enabling the inline calculation of multiple properties of the flow. Calculated flow properties include friction factor, Reynolds number, discharge coefficient, density, viscosity, and corrected flowrate. The present invention further relates to a method of calibration of a differential flow meter and a calibration apparatus for a differential flow meter utilising the same principles.
