Temperature measurement is an important part of many potential applications in the fields of metallurgy. Conventional temperature measurement methods do not provide accurate and precise average temperature of fluid inside an enclosed chamber. The present disclosure provides multi-sensory techniques for measuring average temperature of mixed fluid inside a chamber. The average temperature is measured based on acoustic interferometry technique on standing wave and inputs received from one or more sensors and radar. The present disclosure utilizes radar to compensate the effect of fumes, noise based on Doppler effect. Further, the inputs received from the one or more sensors are used to determine the concentration of one or more fluids present in the chamber. The method of proposed disclosure depends on the principle of dependence of temperature on sound speed in fluid. So, measurement of sound speed can be mapped to report average temperature of mixed fluid inside the chamber.

Provided herein is a differential temperature sensor which utilizes multiple temperature sensors to quickly and accurately calculate ambient fluid temperature with a reduced response time. The provided systems and methods utilize a first fluid temperature sensor and a second probe temperature sensor to account for the thermal impact of the device on the ambient fluid temperature and the effect of heat within the device, or temperature difference between the probe and fluid temperature, on the first fluid temperature sensor measurement.
