Acoustic thermometer operating up to 11 m: uncertainty assessment and new values for Cramer coefficients around 40 kHz
The present article describes an acoustic thermometer to measure the average air temperature integrated along a path ranging from 1 m to 11 m. It is based on time-of-flight measurement of ultrasound pulses at frequencies close to 40 kHz. Several methods for the detection of arrival times were invest...
