摘要
简要介绍了利用磁致伸缩传感器测量液体密度的原理以及测量系统的组成和应用。利用脉冲回波法测量了声速从而算出液体密度。验证了扭转波在液体中传播速度与液体密度的关系。
The density of liquid is measured by using magnetostrictive tech and pulse reflected measurement. It can measure the density successfully and availably by large numbers of experiment. It is an easy and reliable method using the system composed of the magnetostrictive sensor for measuring the density of liquid.
