Multi-sensory techniques for measuring average temperature of mixed fluid inside a chamber

A system (104), comprising:

• a memory (202);
• one or more communication interfaces (204);
• and
• one or more hardware processors (206) coupled to said memory through said one or more communication interfaces, wherein said one or more hardware processors are configured to:
• generate, by exciting a first transducer in a frequency sweep mode, a sound signal to be transmitted to a second transducer in a mixed fluid medium inside a chamber;
• generate, based on transmission of the sound signal, a superimposed standing wave signal between the first transducer and the second transducer;
• analyze, using an acoustic interferometry technique, one or more features of the superimposed standing wave signal to obtain a value of average velocity of the sound signal in the mixed fluid medium inside the chamber;
• determine, using one or more sensors, concentration of one or more fluids present inside the chamber;
• compute, using one or more look up tables, a theoretical value of the velocity of sound signal inside the chamber based on the concentration of the one or more fluids at different temperatures;
• and
• determine average temperature of mixed fluid in the chamber by comparing the theoretical value and the obtained value of sound signal.

One or more non-transitory machine readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• generating, by exciting a first transducer in a frequency sweep mode, a sound signal to be transmitted to a second transducer in a mixed fluid medium inside a chamber;
• generating, based on transmission of the sound signal, a superimposed standing wave signal between the first transducer and the second transducer;
• analyzing, using an acoustic interferometry technique, one or more features of the superimposed standing wave signal to obtain a value of average velocity of the sound signal in the mixed fluid medium inside the chamber;
• determining, using one or more sensors, concentration of one or more fluids present inside the chamber;
• computing, using one or more look up tables, a theoretical value of the velocity of sound signal inside the chamber based on the concentration of the one or more fluids at different temperatures;
• and
• determining average temperature of mixed fluid in the chamber by comparing the theoretical value and the obtained value of sound signal.
