摘要:

介绍了一种内置型全侵浮子液体密度测量仪。该测量仪由浮子、测力传感器等组成，分为单浮子双向测力式和双浮子双向测力式两种。其原理是通过两根杆或弦分别将浮子上下与测力传感器连接，当液体密度发生变化时浮子上下杆或弦中的拉力随之变化，通过测力传感器将上下拉力变化量转变为电流信号输出，从而实现对液体密度的测量。

A kind of fluid density measuring instrument is presented in this papar.There are two sorts: measuring force with one or two floats in two ways.It is made of float, force senor and so on.The upside and down side of float are linken up with two staffs or s
