Which is the best split electromagnetic flowmeter is a question frequently asked by customers recently. There are many split electromagnetic flowmeter manufacturers on the market. If you choose a split electromagnetic flowmeter that suits you? Please listen to the editor to ask you carefully. Come.  The installation of the intelligent electromagnetic flowmeter sensor on the process pipeline  1. The intelligent electromagnetic flowmeter measuring blockage pipe must be completely filled with medium at any time, and it cannot work normally when the pipe is not full or empty. When the medium is not full of the pipe, the method of raising the height of the outlet pipe at the rear of the flowmeter can be used to make the medium full of the pipe to avoid the dissatisfied pipe and the gas from adhering to the electrode. Choose 00001 for the installation location. In order to make the flowmeter work reliable and stable, you should pay attention to the following requirements when choosing the installation location:   a. Try to avoid magnetic objects and equipment with strong electromagnetic fields (such as large motors, large transformers, etc.), To prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor b. It should be installed in a dry and ventilated place as far as possible, and not in a humid, easy to accumulate water c. It should be avoided as far as possible from the sun and rain, and the ambient temperature should be higher than 60 ℃ and relative humidity. More than 95%   d. Choose a place that is easy to maintain and move. e. The flow meter should be installed at the back of the pump, never on the suction side; the valve should be installed on the downstream side of the flow. The location of the pipeline is selected to make the flow meter work reliably. Stable, pay attention to the following requirements when choosing the pipeline installation location;   a. The sensor can be installed on a vertical pipeline, a horizontal pipeline or an inclined pipeline, but the center connection of the two electrodes is required to be in a horizontal state. b. When the electromagnetic flowmeter is working, The measuring tube is always required to be filled with the measured medium. When installing horizontally, in order to ensure this, if necessary, the elevation of the sensor installation position can be slightly lower than the elevation of the pipeline. c. The installation of the flowmeter needs to meet the requirements of the front and rear straight pipe sections. In normal situations, the front section of the flowmeter inlet should be reserved for 10DN, and the flowmeter out Keep 5DN at the back end.  In process automation instruments and devices, flow meters have two major functions: as a detection instrument for process automation control systems and a total meter for measuring the quantity of materials.   Flow meter selection can be considered from five aspects, these five aspects are flow meter performance, fluid characteristics, installation conditions, environmental conditions and economic factors. The detailed factors of the five aspects are as follows:   1. Instrument performance: accuracy, repeatability, linearity, range, flow range, signal output characteristics, response time, pressure loss, etc.;   2, fluid characteristics: temperature, pressure, Density, viscosity, chemical corrosion, abrasiveness, fouling, miscibility, phase change, electrical conductivity, speed of sound, thermal conductivity, specific heat capacity, isentropic index;   3, installation conditions: pipeline layout direction, flow direction, upstream and downstream sides of the test piece Straight pipe length, pipe diameter, maintenance space, power supply, grounding, auxiliary equipment (filter, getter), installation, etc.;    4. Environmental conditions: environmental temperature, humidity, electromagnetic interference, safety, explosion-proof, pipeline vibration, etc. ;  5. Economic factors: instrument purchase costs, installation costs, operating costs, calibration costs, maintenance costs, instrument service life, spare parts, etc.   Kaidi has more than 10 years of flow meter development experience.
