摘　　要：系统采用德国ACAM公司的高精度时间测量芯片GP2来实现超声波检测石油浓度,当超声波在同温度下的均匀混合液体物质中传播时,由于液体浓度不同,在同等距离下超声波传播所需要的时间不同.通过这个时间差就可以区别出相同物质在不同混合液体中的浓度差,从而研制出超声波石油浓度测量仪表.系统采用低功耗单片机MSP430F425作为系统核心芯片,以高分辨时间测量芯片GP2作为采样芯片,高速、有效地完成测量要求.With the help of German＇s company ACAM＇s microchip GP2 we measured the consistency of oil. The ultrasonic velocity, influenced by the consistency of oil, was able to show a measurable difference when it transmited in the oil. So an ultrasonic anemometer and vane based on the theory was developed, and with the superiorities of high integration and ultra low power microcontrollers MSP430F425 as MCU and with the high precision and Time-to-Digital-Converters GP2, and the measurement work was finished efficiently and quickly in the system.
