ABSTRACT:
An apparatus10,70and method is provided that includes a spatial array of unsteady pressure sensors15–18placed at predetermined axial locations x1–xNdisposed axially along a pipe14for measuring at least one parameter of a saturated vapor/liquid mixture12, such as steam, flowing in the pipe14. The pressure sensors15–18provide acoustic pressure signals P1(t)–PN(t) to a signal processing unit30which determines the speed of sound amixpropagating through of the saturated vapor/liquid mixture12in the pipe14using acoustic spatial array signal processing techniques. The primary parameters to be measured include vapor/liquid concentration (i.e., steam wetness or steam quality), vapor/liquid mixture volumetric flow, mass flow, enthalpy, density and liquid droplet size. Frequency based sound speed is determined utilizing a dispersion model to determine the parameters of interest.
