Abstract: The information on the precautions for the use of metal tube float flowmeters is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Before installing the metal tube rotameter, be sure to clean up the welding slag and sundries in the pipeline. In order to ensure the measurement accuracy of the metal tube rotameter, a straight pipe section of not less than 10DN should be added to the inlet end of the flowmeter, and a straight pipe of not less than 5DN should be added to the outlet end. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article on the precautions for using metal tube float flowmeters. Before installing the metal tube rotameter, be sure to clean up the welding slag and sundries in the pipeline. 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. The control valve must be installed downstream of the flowmeter during measurement. . 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 and ensure that the flow of the medium is single-phase stable. damping type. If the measured medium is dirty or contains magnetically conductive particles, a filter or magnetic filter should be installed upstream of the metal tube rotameter. 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. 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, when the metal tube rotameter is used for gas measurement, the working pressure in the pipeline should not be less than 5 times the flow rate. The pressure loss of the meter can be used to make the flowmeter operate stably and normally. Before using the electric remote transmission and metal tube float flowmeter with alarm limit switch, open the instrument cover and wire 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. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Precautions for using metal tube float flow meter'
