Metal Tube Float Flow Meter

Product Overview

Product Features

The principle of metal tube float flow meter is that, in the vertical measuring tube of the flow meter, when the fluid flows

upward through the tube, the float moves upward, at a certain position the lift force of the float and the float gravity

reaches equilibrium, at this time, the flow ring gap area between the float and the orifice plate (or conical tube) maintained

at a certain level. The ring gap area is proportional to the rise height of the float, i.e. a certain height of the float represents

the flow rate. When the float moves up and down, the position is transmitted to the external indicator in the form of a

magnetic coupling, so that the pointer of the indicator follows the float and, with the aid of the cam plate, the pointer

indicates the flow rate value linearly.

使指示器的指针跟随浮子移动，并借助凸轮板使指针线性地指示流量值的大小。

高度成比例，即浮子的某一高度代表流量的大小。浮子上下移动时，以磁耦合的形式将位置传递到外部指示器，

子所受升力与浮子重力达到平衡，此时浮子与孔板(或锥管)间的流通环隙面积保持一定。环隙面积与浮子的上升
