Selection and installation points of split electromagnetic flowmeter

Abstract: The information on the selection and installation of split electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers. According to Weinan and Shunda flowmeter manufacturers, improper selection and installation of flowmeters will affect the accuracy of the use of the instrument at light level, and will affect the service life of the instrument in severe cases, and even damage the instrument. The following and Shunda Technology introduce the split electromagnetic flowmeter in An. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the selection and installation points of the split electromagnetic flowmeter. According to the flowmeter manufacturer, improper selection and installation of the flowmeter will affect the accuracy of the use of the instrument, and even affect the service life of the instrument, and even damage the instrument. The following technology introduces the split electromagnetic flowmeter. When installing the split electromagnetic flowmeter, try to stay away from the vibration source and places with strong electromagnetic interference. Where vibration exists, a vibration damping device must be used to reduce the impact of vibration on the pipeline. The configuration of the straight pipe section, the front and rear straight pipe sections must meet the requirements of the vortex flowmeter, and the inner diameter of the pipe must be the same as the inner diameter of the vortex flowmeter. The following is a specific analysis. There are four main points in the selection of the split electromagnetic flowmeter, and there are six requirements for the installation environment. Four main points for the selection of the split electromagnetic flowmeter: 1. The selection of the split electromagnetic flowmeter should not use the flow rate as much as possible to work at the lower limit value, so the diameter of the flowmeter should be as small as possible to obtain a larger flow rate and flow. scope. 2. The flowmeter should be used within the technical parameters of the medium working pressure and temperature range. Do not deliberately choose instruments with high pressure level and ultra-high temperature, and choose instruments according to the actual working pressure and temperature. The price of the latter is higher. 3. In explosion-hazardous places, explosion-proof split electromagnetic flowmeters should be used. 4. The lower limit flow rate of the split electromagnetic flowmeter depends on the density and kinematic viscosity of the medium, and its upper limit flow rate is generally not affected by the medium pressure and temperature. Therefore, to determine the flow range, it is only necessary to determine the actual available lower limit flow rate. After calculating the lower limit flow, check the flow range table to determine the corresponding diameter. Six requirements for the installation environment of the split electromagnetic flowmeter: 1. Avoid strong electrical equipment, high frequency equipment, and strong switching power supply equipment as much as possible. The power supply for the instrument is separated from these devices as much as possible. 2. Avoid the direct influence of high temperature heat sources and radiation sources. If it must be installed, heat insulation and ventilation measures must be provided. 3. Avoid high humidity environment and strong corrosive gas environment. If it must be installed, there must be ventilation measures. 4. The split electromagnetic flowmeter should try to avoid installing it on the pipeline with strong vibration. If it must be installed, pipe fastening devices must be installed at 2D upstream and downstream, and anti-vibration pads must be added to enhance the anti-vibration effect. 5. The instrument is best installed indoors, and it should be waterproof when installed outdoors. Special attention should be paid to bending the cable into a U shape at the electrical interface to prevent water from entering the amplifier housing along the cable. 6. There should be ample space around the installation point of the instrument for installation wiring and regular maintenance. Flowmeter manufacturers have many years of professional technical personnel engaged in flow instrument automation and rich experience in after-sales service, providing users with full service of design, production, installation, and debugging. The tenet of the factory's operation for many years is: quality assurance, integrity management, door-to-door service is a shortcut for us to communicate with customers, excellent quality, customer satisfaction The above is the whole content of this article, you are welcome to inquire about the flowmeter selection and quotation of our factory.
