The metal tube float flow meter is developed based on the variable area measurement principle; it has a wide range of applications and can be used to measure liquids as well as gases. The metal tube float flow meter features a all-metal structure, offering simplicity in design, reliable operation, accurate measurement, resistance to high temperatures and pressures, as well as easy installation. Changzhou Chengfeng metal tube float flow meters are available in various types, including those with on-site indication, electric remote transmission, and corrosion-resistant versions. Changzhou Chengfeng’s independently developed third-generation metal tube float flow meter further enhances the usability and advantages of such flow meters. It features the following characteristics: an integrated inner and outer cone tube formed in one step, a sturdy and compact design with no dead corners in the measurement tube, a float that can rotate and is less prone to clogging, and magnetic components that are not affected by the Earth’s magnetic field. Low pressure loss design, modular, intelligent, and card-type indicator. The new ESK transmitter is in line with the international market! Advanced foreign computing software is adopted to ensure accurate calculations. Multi-level correction for medium, viscosity, density, temperature, and pressure. Metal tube float flow meters have a wide range of applications. The quality of these flow meters is generally good, but certain faults can still occur during use. Here, Chengfeng Instruments will explain to you what the reasons are for pointer vibration when using metal tube float flow meters I. Slight pointer vibration in metal tube float flowmeters: This is usually caused by fluctuations in the medium, and it can be addressed by increasing damping. II: Moderate pointer jitter: Generally caused by the flow condition of the medium. For gases, this is usually caused by unstable operating pressure of the medium; pressure stabilization or flow stabilization devices can be used to overcome this issue or increase the gas damping effect in float flow meters. III: Severe pointer oscillation: This is mainly caused by medium fluctuations, unstable air pressure, or discrepancies between the pressure, temperature, and flow rate specified by the user for gas operation and the actual conditions of the metal tube float flow meter, resulting in the float flow meter operating outside its range.
