Precautions for installation of metal tube float flow meter

Abstract: The information on the installation precautions of the metal tube float flow meter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Precautions for installation of metal tube rotameter 1. Before installing the meter into the process pipeline, all installations should be dismantled and checked for transportation damage. 2. In order to prevent the flowmeter from being transported, the indicator is equipped with a rubber band to fix the pointer, and the wiring The indicator should be turned on. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the installation precautions for metal tube float flowmeters. Precautions for the installation of metal tube rotameter 1. Before installing the meter into the process pipeline, all installations should be dismantled and checked for transportation damage. 2. In order to prevent the flowmeter from being transported, the indicator is equipped with a rubber band to fix the pointer, and the wiring Open the left cover of the indicator and take it away gently before the pointer position changes. 3 Open the right cover of the indicator, after the cable passes through the cable entry device, connect according to the wiring diagram of the rotation angle transmitter, and then tighten the compression nut , to fix the cable, and then tighten the fastening screws of the left and right covers to make the indicator waterproof and dustproof. 4 The upstream and downstream pipes of the instrument should be the same diameter as the instrument, and 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 h2 should not be less than 250mm. 5 Since the measuring mechanism of the instrument adopts magnetic transmission, in order to ensure the performance of the instrument, the installation surrounding of the sensor should be at least 100mm. The presence of ferromagnetic substances is not allowed. 6 Before the installation of the instrument, the process pipeline should be purged to prevent the ferromagnetic substances retained in the pipeline from adhering to the instrument, affecting the performance of the instrument and even damaging the instrument. If it is unavoidable, it should be Install a magnetic filter at the inlet of the instrument. 7 The instrument for measuring gas is calibrated under a special pressure. If the gas is directly discharged to the atmosphere at the outlet of the instrument, a pressure drop will be generated at the float and cause data distortion. If Under such working conditions, a valve should be installed at the outlet of the instrument so that the required flow value can be set. When the calibration pressure is maintained on the float, the gas will expand at the valve. 8 The installation form of the instrument is divided into For vertical installation and horizontal installation, if it is a vertical installation, the straightness of the instrument should be better than 1%; if it is a horizontal installation, the level of the instrument should be better than 1%. 9 The instrument installed in the pipeline should not be stressed The outlet and inlet of the instrument should be supported by appropriate pipes, so that the instrument can be in a state of minimum stress. 10 When the product is associated with a computer and other operations such as calibration, it must be carried out in a safe place. Special reminder: When installing the flowmeter Before cleaning, blow out the dirt and welding impurities in the pipeline. If the liquid contains solid impurities, a corresponding filter should be installed between the valve and the straight pipe section. Shielding and grounding: In order to ensure the best electromagnetic compatibility of the system Performance, shielding and grounding are very important, especially for bus cables. Shield the cables as continuously as possible. For safe areas, the cables are grounded as much as possible according to routine requirements. Dangerous enough equipotential matching, in this case, multiple grounding is very advantageous. The above is the whole content of this article, you are welcome to inquire about the flowmeter selection and quotation of our factory. 'Installation Precautions for Metal Tube Float Flow Meter'
