All stainless steel glass float flowmeter

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.

旋进旋涡流量计旋进旋涡流量计是目前国内一些小型天然气配气站首要选择的流量计商品，其具备操作温度范畴宽;范围度大;流阻在一定范围内，不受液体温度、压力、密度和粘度影响;适用性强，除含有较大颗粒或较长纤维杂质外，一般不需装过滤器;对上下游直管段规定较低，取上游4D和下游2D直管段即可;输出频率同体积流量成线性相关。

其不足之处是阻力较大，其次，旋进旋涡流量计属液体震动式流量计，对于管路震动和干扰信号较敏感，因此只能在震动较小、无电磁干扰的环境中应用。

工作原理：无线电磁流量计基于LoRa技术的无线流量计由控制，计量，通讯，电源，储存五个模块构成。
