Points for attention when using metal tube rotameter

Abstract: The information on the key points of attention when using the metal tube float flow meter is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. The metal float flowmeter produced by Weinan and Shunda flowmeter manufacturers, the main measuring tube is integrally formed inside and outside, there is no measurement dead angle, the pressure loss is small, the magnetic components are not affected by the geomagnetic field, the indicator is modularly installed, and the viscosity and density of the medium are affected. ,temperature,. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the key points for attention when using metal tube float flowmeters. The metal float flowmeter produced by the flowmeter manufacturer, the main measuring tube is integrally formed inside and outside, there is no measurement dead angle, the pressure loss is small, the magnetic components are not affected by the geomagnetic field, the indicator is installed in a modular manner, and the viscosity, density, temperature, etc. of the medium are affected. Pressure multi-level correction calibration. Compared with the traditional flowmeter, it has the advantages of high precision, good repeatability and small service volume. However, when using it, we also need to pay attention to the following aspects: 1. Before installing the metal tube rotameter, be sure to clean up the welding slag and debris in the pipeline. 2. In order to ensure the measurement accuracy of the metal tube rotameter, a straight pipe section of no less than 10DN should be added to the inlet end of the flowmeter, and a straight pipe section of no less than 5DN should be added to the outlet end. During measurement, the regulating control valve must be installed on the flowmeter. downstream. 3. If the measured medium is a large pulsating flow or two-phase flow, a buffer should be installed upstream of the metal tube rotameter to eliminate or weaken the pulsation to ensure that the flow of the medium is single-phase stable. It is better to use damping type. 4. If the measured medium is dirty or contains magnetically conductive particles, a filter or a magnetic filter should be installed upstream of the metal tube rotameter. 5. The installation of the metal tube rotameter should be able to properly support the vibration of the pipeline or reduce the axial load of the flowmeter, otherwise the support of the fixed flowmeter should be increased. 6. In order to facilitate the maintenance and repair of the metal tube rotameter, the cleaning of the magnetic filter and the regular maintenance of the user's pipeline, it is recommended to use the bypass pipeline as shown in the figure. 7. When the metal tube rotameter is used for gas measurement, it should be ensured that the working pressure in the pipeline is not less than 5 times the pressure loss of the flowmeter, so that the flowmeter can operate stably and normally. 8. Before using the remote transmission and metal tube float flowmeter with alarm limit switch, open the cover of the meter and connect it correctly according to the wiring diagram. For the alarm type, loosen the screw at the limit switch, the user can set the limit alarm position according to the needs, and then tighten the screw and use it after restoration. 9. According to the warning sign in the indicator of the meter, take out the blocking piece that prevents the float from vibrating during transportation, and use the meter after recovery. 10. If the metal tube rotameter is turned on, because there is no pressure in the pipeline or the system has not yet reached the working pressure of the instrument for normal use, the control valve must be opened slowly until the system is normal, and the instrument can be used, otherwise it will easily cause the pointer to jump or the float. Damage caused by sudden impact. 11. When the user uses it, if the density of the fluid to be measured is different from that of water, or the parameters and working conditions of the gas to be measured are different from those specified by the manufacturer, the readings of the metal tube float flowmeter should be converted. Flowmeter manufacturers insist“Technology, Innovation, Quality, Service”development policy, continue to uphold“Build an industrial aircraft carrier and contribute to the national economy”The purpose of the company is to actively participate in the market competition with high-quality products, preferential prices and excellent services, and sincerely cooperate with friends from all walks of life, new and old customers to create brilliance together. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Points to note when using metal tube float flow meter'
