How to properly maintain the metal rotor flow meter

Abstract: The information on the correct maintenance of the metal rotor flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. 1. The metal tube rotameter is a precision device, so during transportation, installation, storage, and use, it must be handled with care to prevent brutal transportation, overstressed installation, and random placement. Make sure that the relative position of the indicator and sensor cannot be changed. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the correct maintenance of metal rotor flowmeters. 1. The metal tube rotameter is a precision device, so during transportation, installation, storage, and use, it must be handled with care to prevent brutal transportation, overstressed installation, and random placement. It must be ensured that the relative position of the indicator and the sensor cannot be changed. Once the relative position changes, it will directly affect the measurement accuracy of the instrument. 2. Metal tube rotameters usually do not require maintenance. However, in the long-term use process, it is inevitable for the pipeline to have ferromagnetic substances adsorbed on the float. If there are too many impurities, the float will be stuck or the measurement accuracy will be affected, so the sensor of the flowmeter should be cleaned. If a magnetic filter is installed at the inlet of the flowmeter, the magnetic filter should also be cleaned regularly. The flowmeter or filter must be removed from the line for cleaning. 3. Before using the electric remote transmission and the flowmeter with alarm limit switch, open the cover of the meter and wire it correctly according to the instructions. 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. 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 instrument to ensure that the float works stably. Generally, the instrument for measuring gas is equipped with a gas damper to minimize the vibration of the float. To further ensure the stability of the float, a throttle valve or suitable orifice plate can be installed at the outlet of the flowmeter. 5. When using the metal tube rotameter, the valve should be opened and closed slowly to avoid damage to the instrument. If the flowmeter is turned on, since 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 to suddenly hit and damage. Phenomenon. 6. 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 reading of the flow meter should be converted. See the correction method for the conversion method. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
