Abstract
The present invention relates to a sensor for measuring the instantaneous rate of mass flow and the cumulative mass flow in steady or unsteady flows of single-phase liquids or gases in a duct. By measuring the shear stress or the streamwise pressure gradient at the duct wall, and relating it to mass flow through solutions to the Navier Stokes equations of fluid mechanics, information on mass flow through the entire duct cross sectional area is deduced.
