02测量原理本系列金属管浮子流量计主要由两大部分组成:传感器和指示器。
传感主要由连接法兰、测量锥管、浮子和上下导向器组成;指示器主要由壳体、磁传动系统、刻度盘和电远传系统组成。
在垂直的锥形测量管内,有一可上下移动的测量部件——浮子(图1),当流体自下而上通过锥形管时,浮子受到流体的作用力,沿锥形管向 上移动。
当流体的流量增大时,浮子的位移量增大;反之,流体的流量减少时,浮子的位移量变小。
也就是说,流体流量的大小,决定了浮子在测量管中的位置,从而决定了浮子和锥形管之间环形面积的大小。
当流体的流量保持在一个恒定的流量Q时,浮子也处于一动平衡状态,停留在锥形管中的一位置h,此时,浮子和锥形管之间的环形面积保持恒定。
浮子受到三个力的作用:浮子的重力G,浮子受到的浮力F,浮子受到流体的作用力P,这三个力达到平衡。
根据流体动力学的柏努力方程、力平衡原理和流体连续性定律,可以计算出此时通过环形面积的瞬时流体流量,所以,金属管浮子流量计是采用可变面积测量流量的原理。
