Matters needing attention in the installation of flow meters

Abstract: Information on matters needing attention in the installation of flow meters is provided by excellent flowmeter and flowmeter manufacturers. As a professional manufacturer of flow meters, temperature meters, pressure meters and level meters, Changzhou Chengfeng Flowmeter insists on developing new technologies, new products, developing technological advantages, developing various flow measuring products, and producing large-scale, systematic and diversified production. . numerous. For more flow meter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the articles that should be paid attention to in the installation of flow meters. As a professional manufacturer of flow meters, temperature meters, pressure meters and level meters, flowmeters insist on developing new technologies, new products, developing technological advantages, developing various flow measuring products, and producing large-scale, systematic and diversified production. What problems should be paid attention to in the installation of various types of flow meters? 1. Before the instrument is installed in the process pipeline, all packaging should be removed and checked for transport damage. And open the case, and remove the filling that fixes the pointer. 2. Before the instrument is installed, the process pipeline should be purged to prevent the ferromagnetic substances remaining in the pipeline from adhering to the instrument, which will affect the performance of the instrument and even damage the instrument. If unavoidable, a magnetic filter should be installed at the inlet of the meter. The instrument itself does not participate in the air sweep before production, so as not to damage the instrument. 3. The upstream and downstream pipes of the instrument should be the same diameter as the instrument, the connecting flange or thread should match the flange and thread of the instrument, the length of the upstream straight pipe section of the instrument should be guaranteed to be 5 times the nominal diameter of the instrument, and the length of the downstream straight pipe section should be greater than or equal to 250mm. 4. The installation form of the instrument is divided into vertical installation and horizontal installation. If it is a vertical installation form, it should be ensured that the angle between the center vertical line of the instrument and the plumb line is less than 2°, if it is installed horizontally, the angle between the horizontal center line of the instrument and the horizontal line should be less than 2°. 5. For instruments with liquid crystal display, try to avoid direct sunlight on the display during installation to reduce the service life of the liquid crystal. 6. The instrument for measuring gas is calibrated under a specific pressure. If the gas is directly discharged to the atmosphere at the outlet of the instrument, it will cause 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. 7. If the instrument transmits signals through magnetic coupling, in order to ensure the performance of the instrument, at least 10cm around the installation, no ferromagnetic substances are allowed. 8. Take special care when installing PTFE-lined instruments. Since PTFE will be deformed under the action of pressure, the flange nut should not be over-tightened arbitrarily. 9. The instrument installed in the pipeline should not be subjected to stress, and the inlet and outlet of the instrument should be supported by appropriate pipes, so that the instrument can be in a state of minimum stress. 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 the installation of flow meters'
