Glass float flowmeter (general type)

Overview.

Glass float flowmeter belongs to the variable area flow meter, mainly used in chemical industry, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dyestuff, environmental protection and scientific research and other departments, used to measure the flow of single-phase non-pulsating (liquid or gas) fluid.

Corrosion-resistant flowmeter is mainly used for corrosive liquid, gas medium flow detection, such as strong acids (except hydrofluoric acid), strong alkalis, oxidizers, strong oxidizing acids, organic solvents and other corrosive gas or liquid medium flow detection.

The measuring cone tube of LZB type uses smooth conical glass tube, and LZJ type uses ribbed conical glass tube.

Working principle.

The main measuring element of the flowmeter is a vertically mounted small conical glass tube and the float that can move up and down inside the tube. When the fluid flows through the conical glass tube from the bottom up, a pressure difference is generated between the upper and lower float, and the float rises under the action of this differential pressure. When this rising force, the buoyancy force and viscous force on the float and the float's gravity equal, the float is in equilibrium position. Therefore, the fluid flow through the flowmeter and the float rise height, that is, with the flowmeter circulation area there is a certain proportional relationship between the float position height can be used as a measure of flow.

夹套金属管浮子流量计有一容下浮球的内腔大家称其为主体管或机壳，它根据法兰或其他接口与器皿构成一个连通器；那样它腔体内的液面与器皿里的液面是相同高度的，因此腔体内的浮球会随着容器内液面的调节而升降；

这时候大家根本无法见到液位，所以我们在箱体的外边装了一个翻柱显示屏，只要我们在制造浮球时在浮球沉到液态与浮出部分的交汇处装上磁瓦，它与浮球随液面调节时，智能玻璃浮子流量计带磁通过机壳传送给翻柱显示屏，促进磁翻柱旋转180°；因为磁翻柱是有红、白2个半圆柱生成的圆柱，因此旋转180°后朝向翻柱显示屏外的会改变颜色（液面下列红色、以上白色），两色交汇处就是液面的高度。
