适航水深测量系统研制成功广州航道局研制成功并通过鉴定的这套系统，其高速密度计在利用声波衰减原理进行高速连续动态测量浮泥密度方面，实现了在１．０～１．４ｇ／ｃｍ３密度范围内声波随浮泥密度增加的单调衰减，避免了双重性；同时实现了单点密度采样时间为０．００... The successful development of seaworthy water depth measurement system The Guangzhou Waterway Bureau successfully developed and passed the identification of the system, the high-speed densimeter in the use of sound attenuation principle of high-speed continuous dynamic measurement of floating mud density, achieved in the 1.0 ~ 1.4g / cm3 density monotonic attenuation of the sound wave with the increase of the density of the mud, to avoid the duality; at the same time to achieve a single-point density sampling time 0.00 ...
