大密度流体密度测量方法与研究

Research on the Measurement Method of High Liquid Density

提出了一种新的大密度（１．２ｇ／ｃｍ３以上）流体密度测量方法一超声波测量法，导出了一种密度与波速之间的关系式，通过测量超声波传播的时间来确定被测流体的密度，用此方法可以实现流体密度的高精度测量。

Abstract A new measurtnent method of higb liquid density, that is ultrasontic testing, is put forward. A relative expression of deasity and wave velocity is derived simultaneously. By meaos ofmeasuriag the time of wave transndssion, the density of liquid is obtaiaed. To measure the liquiddensity on line, a 8098 controlling system is designed
