Ultrasound sensing of concentration of methanol's aqueous solution |
摘要 |
Systems and methods for ultrasound sensing a compound's concentration in aqueous solution are provided. As a result of the ultrasound sensing, an accurate real time measurement of the concentration of the compound of interest in aqueous solution is obtained. In various non-limiting embodiments, the invention provides ultrasound sensing of methanol's concentration in aqueous solution in connection with a fuel circulation process for a direct methanol fuel cell. Since the speed of sound in a water-methanol system increases significantly with methanol content, techniques for measuring characteristic sound velocities are used to give sufficient resolution for a fuel circulation process.
