Glass tube rotor flowmeter is mainly suitable for measuring small flow
2012-3-12 11:01:47

垂直安装在管道上,当流体自下而上流经锥形管时,被转子节流,在浮子的上、下游之间产生差压,转子在此差压作用下上升。 The glass tube rotor flowmeter is installed vertically on the pipe. When the fluid flows through the conical tube from bottom to top, it is throttled by the rotor, and a differential pressure is generated between the upper and lower ends of the float. When the rising force of the rotor is equal to the combined force of gravity, turning force and viscous force, the rotor is in a balanced position. Therefore, there is a certain proportional relationship between the flow rate of the medium flowing through the flow area of the flowmeter and the rising height of the rotor, that is, the flow area of the flowmeter. The glass rotor flowmeter produced by the company is an economical and practical flowmeter, which is mainly used for industrial and laboratory flow monitoring, and can be used to measure liquids and gases. It is mainly suitable for measuring small flow rates, and can measure small flow rates of various clean media. It has more advantages than similar products in micro flow measurement. Additional alarms, differential pressure regulating valves and needle valves can be added as required.

Features

的转子更加稳定和方便读数放大镜的前面板提高了读数的分辨率可更换的流量管和转子方便安装和更换流量管 The measuring tube with guide frame or groove makes the rotor of the glass tube rotor flowmeter more stable and convenient for reading. The front panel of the magnifying glass improves the resolution of the reading. Replaceable flow tube and rotor facilitate the installation and replacement of the flow tube.
"non-rotating" prevents rotation during assembly
OPTIGRAD ™ scales reduce parallax and eye fatigue and can measure corrosive media performance parameters

0.007 ... 0.07ml / min (water) glass tube rotor flowmeter cone made of polysulfone plastic, parts contacting the fluid under test can effectively resist corrosive liquids such as sodium hydroxide solution, saline Ideal special corrosion-resistant flowmeter for chemical industry such as alkali production. Glass Tube Float Flowmeter Jiangsu Dongxiang Instrument provides detailed introduction of glass tube flowmeter. Glass tube rotor flowmeter cone is made of polysulfone plastic. Parts contacting the fluid under test can effectively resist sodium hydroxide solution and salt solution. And other corrosive liquids, it is an ideal special corrosion-resistant flowmeter for chemical industry such as alkali production.
的测量部分为一根垂直安装的锥形聚砜透明管及在内可以上下移动的浮子所组成,锥管大端向上,当流体自下而上流经玻璃管时,在转子上、下之间产生压差,转子在此压差作用下上升。 Characteristics of glass tube rotor flowmeter The measurement part of glass tube rotor flowmeter is composed of a vertically installed conical polysulfone transparent tube and a float that can be moved up and down inside. The large end of the cone tube is upward. When a glass tube is used, a pressure difference occurs between the upper and lower parts of the rotor, and the rotor rises under the action of this pressure difference. When the force that causes the rotor to rise is equal to the combined forces of gravity, buoyancy, and viscous force, the float is in a balanced position, which is a measure of flow.
