Introduce glass tube rotor flowmeter
2011-11-29 11:01:38

分普通型、耐腐型、全不锈钢型、不锈钢耐腐性…… Glass tube rotor flowmeter is divided into ordinary type, corrosion resistance type, all stainless steel type, stainless steel corrosion resistance ...

  主要用于化工,石油,轻工,医药,化肥,化纤,食品,染料,环保及科学研究等各个部门中;用来测量单相非脉动(液体或气体)流体的流量; Glass tube rotor flowmeter is mainly used in chemical, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dyes, environmental protection and scientific research and other departments; used to measure the single-phase non-pulsating (liquid or gas) fluid flow;

主要用于有腐蚀性液、气体介质流量的检测、例如强酸(氢氟酸除外),强碱,氧化剂,强氧化性酸,有机溶剂和其它具有腐蚀性气体或液体介质的流量检测。 Anti-corrosive glass rotor flowmeter is mainly used to detect the flow of corrosive liquids and gaseous media, such as strong acids (except hydrofluoric acid), strong alkalis, oxidants, strong oxidizing acids, organic solvents and other corrosive gases or liquids Flow detection of media.
The main measuring element is a vertically mounted lower and upper conical glass tube and a float that can move up and down inside; when the fluid passes through the conical glass tube from bottom to top; a pressure difference occurs between the upper and lower sides of the float, It rises under the action of this differential pressure; when the rising force, the buoyancy and viscous lift force on the float are equal to the gravity of the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the flow rate of the fluid flowing through the flowmeter and the rising height of the float, that is, the area of the flow meter of the flowmeter; the position height of the float can be used as a flow measurement;
Ordinary type: mainly suitable for measurement of non-corrosive media;


Corrosion-resistant type: mainly suitable for the measurement of corrosive media;


All stainless steel type: mainly suitable for hygienic and weakly corrosive medium measurement, can resist corrosive gas in the use environment;

Stainless steel corrosion-resistant type: mainly suitable for measurement of strong corrosive media, can resist corrosive gases in the use environment;
