该流量计包括厚度测量功能，能有效测量液体声速。
The flowmeter includes a thickness measurement function and can effectively measure the sound velocity of fluids.
另一方面实现了速度综合的自校正，这种校正方法能适应各种不同规律的液体媒介的声速变化。
One hand, it extends the ultrasonic measure to dynamic; On the other hand it can roundly correct velocity in all kinds of liquid medium.
所有的数据，包括液体密度、粘度、声速、连续折射率，都在井下油藏温度和压力条件下测得。
Measurements of fluid density, viscosity, sound speed, and continuous refractive index are made downhole under reservoir temperature and pressure conditions.
