高温高粘型椭圆齿轮流量计
FG系列
原理                                                                                   
由计量箱和装在计量箱内的一对椭圆齿轮,与上下盖板构成一个密封的初月形空腔(由于齿轮的转动,所以不是**密封的)作为一次排量的计算单位。当被测液体经管道进入流量计时,由于进出口处产生的压力差推动一对齿轮连续旋转,不断地把经初月形空腔计量后的液体输送到出口处,椭圆齿轮的转数与每次排量四倍的乘积即为被测液体流量的总量      
结构                                                                                   
"椭圆齿轮流量计由流量变送器和计数机构组成。变送器与计数机构之间加装散热器,则构成高温型流量计。变送器由装有一对椭圆齿轮转子的计量室和密封联轴器组成,计数机构则包含减速机构、调节机构、计数器、发讯器。
