Patent
System for temperature profile measurement in large furnances and kilns and method therefor
P. Shakkottai,S. P. Venkateshan +1 more
TL;DR: In this paper, the times of flight of sound waves were used to determine temperature in a gas contained in a long tube which confines sound waves, and corrections for thermal expansion of the tube were easily made.
PatentDOI
Acoustic humidity sensor
TL;DR: In this paper, the water vapor content for air in drier ducts, ovens, furnaces and the like is determined by a measurement of sound speed which is done by measuring the time difference between sound pulses reflected by two reflectors spaced a known distance apart in a guide tube.
PatentDOI
Dual tube sonic level gage
P. Shakkottai,E. Y. Kwack +1 more
TL;DR: In this paper, a dual tube sonic level gage is used to measure liquid levels in a tank using plane waves of sound propagated in two vertical tubular wave guides to locate the levels of liquid contained in each tube.
Patent
Acoustic device and method for measuring gas densities
TL;DR: In this article, the authors present a simple design of a dipole sound source with a small tube and a receiver transducer on the circumference of the small tube located a small distance away from the transmitter.
Journal ArticleDOI
Acoustic temperature profile measurement technique for large combustion chambers
TL;DR: In this paper, an acoustic waveguide where the outside temperature profile is transferred to a chosen gas contained inside the guide is described. But it is not suitable for the measurement of time of flight of sound waves.
