|(In Japanese)発明の名称||ACOUSTIC VELOCITY MEASURING METHOD AND INSTRUMENT OF HIGH RESOLUTION FOR FLUID|
PROBLEM TO BE SOLVED: To provide an acoustic velocity measuring method and an instrument of high resolution capable of measuring an acoustic velocity at 1 ppm of resolution even under a pressurized condition, and capable of knowing clearly a delicate change in the volume or elasticity of a substance or a substance contained therein.
SOLUTION: A sound wave is generated and detected in a resonator by the same transducer, an acoustic cavity (acoustic resonator) is thereby compactified and a measuring system is thereby simplified. A required sample amount is reduced further (sound path length 3 mm, sample amount 10 μl), and a temperature is easily stabilized in addition thereto. When generating/detecting a signal compatibly by the same transducer, a sound wave signal propagated through a route other than an input signal or the sample is favorably removed to detect only a resonance sound wave signal in the sample.
