Insertion electromagnetic flow meter installation precautions

Abstract: The information on the installation precautions of the plug-in electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter production and quotation manufacturers. The plug-in type is mainly used to measure the volume flow in conductive liquids and slurries in closed pipes. Including strong corrosive liquids such as acid, alkali, salt, etc. Insertion electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the article on the installation precautions of plug-in electromagnetic flowmeters. The plug-in type is mainly used to measure the volume flow in conductive liquids and slurries in closed pipes. Including strong corrosive liquids such as acid, alkali, salt, etc. Insertion electromagnetic flowmeter is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. There are several points to pay attention to during the installation of the plug-in electromagnetic flowmeter: The plug-in electromagnetic flowmeter has self-test and self-diagnosis functions, which is convenient for maintenance, and the measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The installation requirements that need to be known when installing the electromagnetic flowmeter are as follows: 1. Installation environment of the electromagnetic flowmeter 1. The 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. Pipes are securely fastened. The ambient temperature does not change much. 3. The installation location should be convenient for installation and maintenance. 2. Selection of the installation position of the plug-in electromagnetic flowmeter 1. The installation position must ensure that the pipeline is always filled with the fluid to be measured. 2. 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 is not less than 5D. 3. Installation of the plug-in electromagnetic flowmeter sensor 1. Clean the welding slag and burrs on the installation base of the tube under test. 2. Install the DN50 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. 3. Install the compression threaded seat kit on the ball valve, loosen the positioning screw and compression nut, and insert the sensor insertion rod into the pipe under test through the ball valve. 4. 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. 4. Welding of the mounting base 1. The opening on the pipe under test is larger than the base¢51 tube, base¢51 The depth of the opening where the pipe is inserted into the pipe to be tested is flat on both sides of the weld; 2. The plug-in electromagnetic flowmeter adopts stainless steel electrode for flat welding, and after welding, ensure that the flange surface is parallel to the axis of the pipe. 5. Adjustment and use of the plug-in electromagnetic flowmeter 1. Connect the power supply and other connections with the converter gauge according to the requirements of the plug-in electromagnetic flowmeter's manual. When zero, look at the meter display should be zero. 2. After the fluid in the tube to be tested is flowing and stable, check the display of the instrument. At this time, turn the direction of the sensor to maximize the display value, and then lock the positioning screw and the compression nut. Insertion electromagnetic flowmeters can provide bidirectional high-precision measurement and are ideal flowmeters for leak detection. At the same time, the excellent reproducibility ensures that only true flow mutations are detected. The above is the whole content of this article.
