Method and apparatus for determining gasoline characteristics by using ultrasonic wave
First Claim
1. An ultrasonic-type gasoline characteristic determination apparatus for determining gasoline volatility characteristics by using an ultrasonic wave having a measured velocity, comprising:
- a transducer for transmitting and receiving an ultrasonic wave in a gasoline;
distance varying means for correcting the distance between the transmission and reception of said ultrasonic wave on the basis of the temperature of said gasoline; and
means for determining the volatility characteristics of the gasoline from the measured velocity of said ultrasonic wave.

Abstract
The present invention relates to the measurement of gasoline volatility characteristics, and is directed in particular to the provision of an ultrasonic-type gasoline characteristic determination method and apparatus capable of determining the volatility characteristics with good accuracy by measuring the velocity of an ultrasonic wave in a gasoline containing alcohol or other additives and by compensating for deviations from a reference temperature, and a method for determining gasoline volatility characteristics by using an ultrasonic wave is provided, comprising the steps of transmitting an ultrasonic wave into a gasoline being measured, measuring the velocity of the ultrasonic wave in the gasoline, and determining the volatility characteristics of the gasoline from the velocity.
