Dongxiang Instrument LZB is a domestic system with strong versatility, simple structure and convenient maintenance. Segmented measurement, flexible measurement range, and small flow can be measured. The test body is made of various materials and can measure corrosive media. With a regulating valve below DN10, it is convenient for users. 在使用安装前，应先检查技术参数如：测量范围，精确度等级，额定工作压力，温度等参数是否符合使用要求。 There are the following requirements during installation and use: 1. Before using the glass rotor flowmeter , check the technical parameters such as: measurement range, accuracy level, rated working pressure, temperature and other parameters that meet the requirements for use. 2. Before installation, remove the top lining which is used for transportation protection. And check the cone tube for damage, whether the float can move up and down freely, and it can be installed only after it is normal. 3. The newly installed pipeline should be flushed clean. 4. Make the minimum graduation value of the rotor flow meter below and install it vertically on a pipe without vibration. The angle between the center line of the rotor flow meter and the plumb line should not exceed 5 degrees. Large-caliber flowmeters are heavy. To avoid pipe bending, measures such as reinforcement and support can be taken if necessary. 5. During installation, the rotor flowmeter should be protected from excessive external force, such as pressure and torque. 6. If necessary, install a filter upstream of the rotor flowmeter to block the rotor flowmeter according to different working conditions in use to prevent contamination by impurities. 7. If the fluid is unstable and has a pulsating flow, a buffer can be installed to ensure the good measurement of the rotor flowmeter to eliminate the pulsating flow. 8. When the rotor flowmeter is in use, slowly open the control valve on the upstream pipe of the flowmeter, and then use the regulating valve to adjust the flow rate, so as to avoid the sudden rise of the float and the damage to the cone tube. 9. In order to obtain accurate measurement accuracy, it is recommended that the common flow rate of the measured fluid should be more than 60% of the graduated flow rate of the rotor flow meter.
由于流量计本体大部分为玻璃材质，使用及运输就要必须要小心。 Since the glass tube rotor flowmeter is mostly made of glass, care must be taken in its use and transportation. Dongxiang Instruments sends glass rotor flowmeters to customers for express delivery in wooden cases. If there is any problem during transportation, we promise to replace it. Ensure customers can use our products with satisfaction
Glass Rotameter Products
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。 Glass rotor flowmeters are widely used in chemical, petroleum, light industry, pharmaceutical, environmental protection, food and metrology testing, scientific research and other departments to measure the flow rate of single-phase non-pulsating fluids (liquid or gas).
Corrosion-resistant glass rotor flowmeter has strong corrosion resistance, can detect the flow of acids (except hydrofluoric acid), alkali, oxidants and other corrosive gases or liquids, suitable for chemical, pharmaceutical, papermaking, sewage treatment and other industries .
Principle and structure of glass rotor flowmeter:
The flow meter 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 of the fluid. 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.
