Abstract:
A sensing system for measuring a fluid mixture in a pipe, comprising:a first temperature sensor for providing a first temperature signal indicative of the temperature of the fluid mixture; a first pressure sensor for providing a first pressure signal indicative of the pressure of the fluid mixture; a velocity sensor for providing a velocity signal indicative of the velocity of the fluid mixture, wherein the velocity sensor passively senses pressure disturbances occurring within the fluid mixture without detecting acoustical energy added to the fluid mixture by the sensing system; a sound speed sensor for providing a sound speed signal indicative of the fluid sound speed in the fluid mixture, wherein the sound speed sensor passively senses pressure disturbances occurring within the fluid mixture without detecting acoustical energy added to the fluid mixture by the sensing system; and a logic system for receiving the first temperature signal, the first pressure signal, the velocity signal, and the sound speed signal.
