| titleOfInvention | Method and apparatus for measuring alcohol concentration |
| abstract | (57) Abstract: The present invention relates to a method for measuring the concentration of alcohol, and in particular, by measuring the sound speed of ultrasonic waves in a solution to which alcohol is added, and measuring the rate of temperature change of the sound speed. The present invention relates to a method and an apparatus for measuring an alcohol concentration, which can accurately determine the alcohol concentration. SOLUTION: A method for measuring the concentration of alcohol using ultrasonic waves, comprising: transmitting ultrasonic waves into an aqueous alcohol solution to be measured; and measuring a speed of the ultrasonic waves in the aqueous alcohol solution. Heating the alcohol aqueous solution, measuring the speed of ultrasonic waves in the alcohol aqueous solution after heating, and measuring the alcohol concentration by changing the ultrasonic wave propagation speed before and after heating in the alcohol aqueous solution And characterized in that: |
