About the measurement accuracy of the metal tube float flow meter

Abstract: The information about the measurement accuracy of the metal tube float flow meter is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. With the development of the instrumentation industry now, because of the characteristics and advantages of the metal tube rotameter (small pressure loss, large detection range, and convenient use), it has become a commonly used flow measurement instrument in industrial automation process control. It can be used to measure liquids, gas with. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article about the measurement accuracy of metal tube float flowmeters. With the development of the instrumentation industry now, because of the characteristics and advantages of the metal tube rotameter (small pressure loss, large detection range, and convenient use), it has become a commonly used flow measurement instrument in industrial automation process control. It can be used to measure liquids, The flow rate of gas and steam is especially suitable for medium flow measurement with low flow rate and small flow rate. Therefore, we must pay attention during installation to ensure the normal use of the metal tube rotameter and its accuracy. Try to avoid direct sunlight and high temperature environment (≥65°C) so as not to reduce the capacity and life of the lithium battery. In order to ensure the normal operation of the metal rotameter and achieve the required measurement accuracy, the following points should generally be noted: 1. The metal rotameter must be installed vertically on a vibration-free pipeline, the fluid flows through the flowmeter from bottom to top, and the verticality better than 2°, the horizontal angle is better than 2 when installed horizontally°, In order to facilitate the maintenance and replacement of the flowmeter, clean the measuring pipeline, the metal tube float flowmeter installed on the process pipeline should be equipped with bypass and bypass valve. 2. There should be a straight pipe section with a length of more than 5 times the pipe diameter at the entrance of the metal pipe rotameter. The outlet should have a 250mm straight pipe section. 3. If the medium contains ferromagnetic substances, a magnetic filter should be installed; if the medium contains solid impurities, a filter should be considered between the valve and the straight pipe section. 4. 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, so that the float can work stably. 5. When heat insulation protection measures are required, if the temperature of the measured medium is higher than 220°C or the temperature of the fluid is too low, crystallization is likely to occur. Jacket type should be selected for cooling or insulation. 6. Pipe flanges, fasteners, gaskets and flowmeter flanges have the same standard to enable the instrument to be installed and run normally. 7. The failure of metal tube rotameter generally occurs when the device is just started, because the pipeline is not flushed cleanly, and When the float is stuck by solid particles, the pointer of the indicator stops at one position. At this time, the valves on both sides of the flowmeter should be closed first, then the upper flange should be removed, the float should be taken out for cleaning, and then reinstalled. Note that the tightening of the upper flange nut should be balanced and tightened, and the gasket should be well cushioned. 8. The flange of the process pipeline must be coaxial with the flange of the flowmeter and parallel to each other, in order to avoid deformation of the flowmeter due to the pipeline. Proper pipeline support to avoid pipeline vibration and reduce the axial load of the flowmeter, the control valve in the measurement system should be installed downstream of the flowmeter. 9. At least 10cm around the installation, because the instrument transmits signals through magnetic coupling, in order to ensure the performance of the instrument, ferromagnetic substances are not allowed. A meter that is calibrated to measure gas at a specific pressure if the gas is vented directly to the atmosphere at the meter's outlet. This will create a pressure drop at the float and cause data distortion. If this is the case, a valve should be installed at the outlet of the meter. 10. Be extra careful. Due to uneven pressure, when installing PTFE-lined instruments. PTFE will deform, so the flange nuts are evenly tightened symmetrically. 11. When installing, try to avoid direct sunlight on the display, and the meter with liquid crystal display. So as not to reduce the life of the LCD. Metal tube rotameter, as one of the most important current flow instruments, has been developed at a high speed. Now the third generation of metal tube rotameter has been newly developed, which further improves the availability and advantages of metal tube rotameter. It has the following characteristics: one-time forming of the inner and outer tapered tubes, solid and simple measuring tube without dead ends, the float can be rotated and not easy to be blocked, and the magnetic components are not affected by the earth's magnetic field. Low pressure loss design, modular, intelligent, clip-on indicator. The new ESK transmitter is in sync with the international market! The introduction of foreign advanced calculation software ensures accurate calculation. Multi-level correction of medium, viscosity, density, temperature and pressure. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Measurement Accuracy of Metal Tube Float Flow Meter'
