Selection and Installation of Large Diameter Electromagnetic Flow Meter

Abstract: The selection and installation information of large-diameter electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Intelligent electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquids and slurries in closed pipes. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc., intelligent electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the selection and installation of large-diameter electromagnetic flowmeters. Intelligent electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquids and slurries in closed pipes. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc., intelligent electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. The correct selection of large-diameter electromagnetic flowmeter determines the accuracy of measurement, so what type of large-diameter electromagnetic flowmeter should be selected should be determined according to the physical and chemical properties of the fluid medium to be measured, so that the diameter of the large-diameter electromagnetic flowmeter can be The flow range, lining material, electrode material and output current, etc., can be adapted to the properties and properties of the fluid to be measured and the flow rate requirements. From the working principle of the large-diameter electromagnetic flowmeter, it can be known that the large-diameter electromagnetic flowmeter can be selected. The fluid for measuring the flow rate must be conductive. Strictly speaking, except for high-temperature fluids, as long as the conductivity is greater than 5μFor any fluid of /cm, the corresponding large-diameter electromagnetic flowmeter is used to measure the flow. Therefore, non-conductive gas, steam, oil, acetone and other substances cannot be measured with a large-diameter electromagnetic flowmeter. Determination of sensor diameter The flow rate of the flowmeter is in the range of 0.3-15m/s. At this time, the diameter of the flowmeter can be selected to be consistent with the diameter of the user's pipeline. When the flow velocity is lower than 0.3m/s, the flow velocity is locally increased at the instrument site, and the tube shrinking method is adopted: The next step is the choice of integrated type or separate type. The integrated type is selected when the on-site environment is good, that is, the sensor and the converter are assembled into one. Separate type means that the sensor and converter are installed in different locations separately. After the correct selection of the model, in order to make the large-diameter electromagnetic flowmeter work stably, the correct installation is also particularly important. Try to avoid ferromagnetic objects and equipment with specific strong electromagnetic fields (such as large motors, large transformers, etc.), so as to avoid the magnetic field affecting the working magnetic field and flow information of the sensor; it should be installed in a dry and ventilated place as much as possible. Local installation; should try to avoid sun and rain, avoid ambient temperature higher than 45 ℃ and relative humidity higher than 95%; choose a place that is convenient for maintenance and activities; large-diameter electromagnetic flowmeter should be installed at the back end of the pump, and must not be installed in the pump. The suction side is installed; the valve should be installed on the downstream side of the flowmeter. The above is the whole content of this article.
