Flow meter
Glass tube rotor flowmeter

玻璃管转子流量计广泛应用于化工、石油、轻工、医药、环保、食品及计量测试、科学研究等部门,测量单相非脉动流体(液体或气体)的流量。 LZB / LZJ series glass tube rotor flowmeter is widely used in chemical, petroleum, light industry, medicine, environmental protection, food and metrology testing, scientific research and other departments to measure the flow rate of single-phase non-pulsating fluid (liquid or gas).
有较强的耐腐性能,可检测酸(氢氟酸除外)、碱、氧化剂和其它腐蚀性的气体或液体的流量,适用于化工、制药、造纸、污水处理等行业。 LZB / () F / LZJ- () F series corrosion-resistant glass tube rotor flowmeter has strong corrosion resistance and can detect the flow of acids (except hydrofluoric acid), alkalis, oxidants and other corrosive gases or liquids , Suitable for chemical, pharmaceutical, papermaking, sewage treatment and other industries.

Shape and installation dimensions

Principle and structure

主要由一根自下而上扩大的锥形玻管和一只随流体流量大小上下移动的浮子组成(图3)。 The glass tube rotor flowmeter is mainly composed of a conical glass tube that expands from bottom to top and a float that moves up and down with the flow rate of the fluid (Figure 3). When the fluid flows through the cone from bottom to top, the lift force S generated by the fluid kinetic energy on the float and the buoyancy A of the fluid rise the float. When the sum of the lift force S and the buoyancy A is equal to the float's own gravity G, the float is in equilibrium and stabilized At a height position, the scale on the cone indicates the flow rate of the fluid.
中浮子读数位置按图2所示: The position of the float reading in the glass tube rotor flowmeter is shown in Figure 2:

流量计锥管为光滑内壁管(见图4),通径DN15以上的流量计,浮子通过导杆上下移动,保持稳定;LZJ/LZJ-( )F流量计锥管内壁有三条导向凸筋,使浮子保持稳定(见图4)。 LZB / LZB- () F glass tube rotor flowmeter cone tube is a smooth inner wall tube (see Figure 4), flowmeters with a diameter of DN15 or more, the float moves up and down through the guide rod to maintain stability; LZJ / LZJ- () F flow rate There are three guiding ribs on the inner wall of the metering tube to keep the float stable (see Figure 4). 采用软管连接,配有针形流量调节阀;通径DN15以上流量计采用法兰连接。 Glass tube rotor flowmeters with a diameter below DN10 are connected by hoses and equipped with needle-shaped flow regulating valves; flowmeters with a diameter above DN15 are connected by flanges.

If the wetted material is 316, the model is LZB- () Bo, which needs to be customized.
If stainless steel lined with PTFE is required, the model is LZB- () BF (or BoF), which needs to be customized.

All-tetrafluoro

The base, float and needle valve are made of polytetrafluoroethylene (PTTFE). Support plate, screws, etc. are made of stainless steel
