Anti corrosion LZB glass rotor flowmeter LZB-25F glass rotor flowmeter

Description :

　　1. Overview:

　　This product has the characteristics of high sensitivity, wide measurement range, and easy use and maintenance. The connection method of the instrument is flange connection. A flowmeter that uses changes in flow cross-section to measure non turbid and non pulsating liquid or gas flow under constant pressure conditions. Widely used in petroleum, chemical, metallurgical, synthetic fiber, dye, papermaking, environmental protection equipment, food, sugar production, as well as supporting facilities for scientific experimental instruments.

　　2、 Principle and Structure:

　　The main measuring element is a vertically installed conical glass tube (referred to as a cone tube) with a small end facing downwards and a large end facing upwards, as well as a float that can move up and down inside. When the fluid flows through the conical tube from bottom to top, a pressure difference is generated between the floats, and the floats rise under this pressure difference. When the lift force of the float is equal to the combined force of gravity, buoyancy, and viscosity, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the flow rate of the fluid flowing through the glass rotor flowmeter and the rising height of the float, that is, the fluid area of the instrument. The height of the float position can be used as a measure of the flow rate.

　　3、 Purpose:

　　Glass rotor flow meters are mainly used in various departments such as chemical, petroleum, light industry, medicine, fertilizer, synthetic fiber, food, dye, environmental protection, and scientific research to measure the flow rate of single-phase non pulsating (liquid or gas) fluids. The corrosion-resistant glass rotor flowmeter is mainly used for detecting the flow rate of corrosive liquids and gas media, such as strong acids, strong bases, oxidants, strong oxidizing acids, organic solvents, and other corrosive gas or liquid media.

　　4、 Installation:

　　1. It must be installed vertically on a vibration free pipeline. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2 °;

　　2. For the convenience of maintenance, replacement of flow meters, and cleaning of measurement pipelines, the FA24 glass rotor flow meter installed on the process pipeline should be equipped with bypass pipelines and bypass valves;

　　3. The inlet of the rotor flowmeter should have a straight pipe section of at least 5 times the diameter of the pipe, and the outlet should have a straight pipe section of 250mm;

　　4. If the medium contains ferromagnetic substances, a magnetic filter should be installed; If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section;

　　5. When used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure stable operation of the float;

　　6. In order to avoid deformation of the flow meter caused by the pipeline, the flange of the process pipeline must be coaxial and parallel to the flange of the flow meter. The pipeline support should be used to avoid pipeline vibration and reduce the axial load of the FA24 glass rotor flow meter. The control valve in the measurement system should be installed downstream of the flow meter;

　　7. When measuring gas, if the gas is directly discharged into the atmosphere at the outlet of the flowmeter, a valve should be installed at the outlet of the instrument, otherwise a pressure drop will occur at the float, causing data distortion.
