Installation skills of metal tube float flow meter

Abstract: The installation skills information of metal tube float flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. Metal tube rotameter is a kind of flow measuring instrument commonly used in industrial automation process control. It can be used to measure the flow of liquid and gas, especially suitable for low flow rate and small flow medium flow measurement. When installing, try to avoid direct sunlight and high temperature rings. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on installation skills of metal tube float flowmeters. Metal tube rotameter is a kind of flow measuring instrument commonly used in industrial automation process control. It can be used to measure the flow of liquid and gas, especially suitable for low flow rate and small flow medium flow measurement. When installing, try to avoid direct sunlight and high temperature environment to avoid reducing the capacity and life of the lithium battery. In order to ensure the normal operation of the metal tube rotameter and achieve the required measurement accuracy, the following points should generally be noted: 1. The fluid flows through the flowmeter from bottom to top, and the metal tube rotameter must be installed vertically. and the verticality is less than 2°, the horizontal angle is less than 2 when installed horizontally°, so that the production will not be affected when dealing with faults or purging; the metal tube rotameter installed on the process pipeline should be bypassed. 2. There should be a 250mm straight pipe section at the outlet, and a straight pipe section with a length of more than 5 times the pipe diameter at the entrance of the metal tube rotameter. In order to ensure the measurement accuracy of the instrument. 3. If the medium contains ferromagnetic substances, consider installing a magnetic filter between the valve and the straight pipe section. 4. When it is used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter, so that the float can work stably. When heat insulation protection measures are required, if the temperature of the measured medium is higher than 220°C or the fluid temperature is too low and crystallization is likely to occur, the jacket type should be selected for cooling or heat preservation. 5. Pipe flanges, fasteners, and gaskets are the same as the flowmeter flange standards to enable the normal installation and operation of the instrument. 6. The product does not need maintenance after the device is in normal operation. The fault mostly occurs when the device is just running, because the pipeline is not cleaned cleanly, and the float is stuck by solid particles, and the pointer of the indicator stops at a certain position. At this time, the valves on both sides of the flowmeter should be closed first, the flowmeter should be removed, and the float should be taken out for cleaning. (Note: For a horizontally installed flowmeter, directly remove the upper flange and take out the float for cleaning. balance and tighten) and reassemble. 7. The flange of the process pipeline must be coaxial with the flange of the flowmeter and parallel to each other, in order to avoid the deformation of the flowmeter caused by the pipeline. Appropriately increase the pipeline support to avoid pipeline vibration and reduce the axial load of the flowmeter. 8. In order to ensure the performance of the meter, ferromagnetic substances are not allowed to exist at least 100mm around the meter installation, because the meter transmits signals through magnetic coupling. . 9. The instrument for measuring gas is calibrated under a specific pressure. If the outlet is directly discharged to the atmosphere, it will cause a pressure drop at the float and cause data distortion; if it is such a working condition, it should be installed at the outlet of the instrument a regulating valve. 10. Under the action of uneven pressure, PTFE will be deformed when installing the PTFE-lined instrument, so the flange nuts are evenly and symmetrically tightened. The above is the entire content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Installation Skills of Metal Tube Float Flow Meter'
