Insertion electromagnetic flow meter installation requirements

Abstract: The information on the installation requirements of the plug-in electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter production and quotation manufacturers. Installation requirements and precautions of plug-in electromagnetic flowmeter Accurate measurement requires the selection of the correct instrument, the quality of the instrument is the main thing, and the second is to consider the installation requirements. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the installation requirements of the plug-in electromagnetic flowmeter. Installation requirements and precautions of plug-in electromagnetic flowmeter Accurate measurement needs to choose the correct instrument, the quality of the instrument is the main thing, and the second is to consider the installation requirements. We must pay attention to the installation of the plug-in electromagnetic flowmeter. The technical staff of Shanghai Yibi Company will introduce the installation requirements and precautions of the plug-in electromagnetic flowmeter for you: 1. The plug-in electromagnetic flowmeter should be kept away from equipment with strong electromagnetic fields as far as possible; 2. There should be no strong vibration in the installation site, the pipeline is fixed firmly, and the ambient temperature changes little; 3. The installation location must ensure that the pipeline is always filled with the measured fluid, the length of the straight pipe section on the upstream side of the sensor installation pipeline is greater than 8D, and the length of the straight pipe section on the downstream side Not less than 5D; 4. Clean up the welding slag and burrs on the mounting base of the tube under test; 5. Install the DN80 ball valve on the mounting base, pay attention to the long cavity of the ball valve upwards, and check that the ball valve switch is normal; Install the compression threaded seat kit to the ball valve , loosen the positioning screw and the compression nut, and insert the sensor insertion rod into the pipeline under test through the ball valve. The insertion depth of the sensor is 3mm beyond the base. After meeting the requirements, tighten the positioning screw and the compression nut. Also note that the sensor direction mark is consistent with the fluid flow direction. 6. The opening on the pipeline to be tested is larger than that of the base tube, and the depth of the opening where the base tube is inserted into the pipeline to be tested is flat on both sides of the weld; 7. The plug-in electromagnetic flowmeter is flat-welded with stainless steel electrodes. The axis of the tube is parallel; 8. Connect the power supply and other connections with the converter standard meter according to the requirements of the plug-in electromagnetic flowmeter's manual. After power-on, check the display of the meter to confirm that the tube under test is full of fluid and the flow rate is zero. Check the meter The display should be zero; 9. After the fluid in the tube to be tested is flowing and stable, check the display of the meter. At this time, turn the sensor direction to maximize the displayed value, and lock the positioning screw and compression nut; 10. For the large flow range and fluid velocity If the flow rate is lower than the minimum flow rate required by the flowmeter for a long time, it should be considered to reduce the process pipeline or use two flowmeters installed in parallel; 11. The insertion electromagnetic flowmeter is the same as the ordinary electromagnetic flowmeter. This can prevent suspended solids from falling on the electrode, and at the same time make the oil in the fluid rise beyond the measuring range of the electrode. If the flowmeter is installed on a horizontal process pipeline, the electrode of the sensor should be on the horizontal axis. , to avoid the interference of the electrode due to air bubbles, resulting in measurement errors; 12. Vertical installation, the angle between the sensor and the vertical diameter of the pipeline section should be less than 5°, suitable for measuring the cleaning medium with small vibration of the pipeline; 13. Inclined installation, the angle between the axis of the sensor and the axis of the measured pipeline is 45°, It is suitable for liquid flow measurement with large pipe diameter and other impurities in the measurement medium. This installation method has small water resistance and is not suitable for entanglement. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Installation Requirements for Insertion Electromagnetic Flow Meters'
