The price of split electromagnetic
flowmeter is a problem that many customers are very concerned about. If you want to know the price of split electromagnetic flowmeter, you must know the principle of split electromagnetic flowmeter. Introduction to flowmeters Electromagnetic Flowmeters (EMF) is a new type of flow measurement instrument that developed rapidly with the development of electronic technology in the 1950s and 1960s. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. The split electromagnetic flowmeter is an inductive instrument that measures the volume flow of the conductive medium in the tube according to Faraday's law of electromagnetic induction. It uses single-chip embedded technology to realize digital excitation. At the same time, it uses CAN fieldbus on the electromagnetic flowmeter. It is a domestic initiative. The technology has reached the leading domestic level. The split type electromagnetic flowmeter can output 4-20mA current signal for recording, adjustment and control while meeting on-site display. It has been widely used in chemical industry, environmental protection, metallurgy, medicine, papermaking, water supply and drainage and other industrial technologies and Management department. In addition to measuring the flow of general conductive liquids, the split electromagnetic flowmeter can also measure the volumetric flow of liquid-solid two-phase flow, high-viscosity liquid flow, and salt, strong acid, and strong alkali liquids. Three elements of electromagnetic flowmeter selection: flowmeter diameter (caliber), electrode material, lining material 1, flowmeter diameter (determined according to flowmeter pipe wall thickness and pipe outer diameter); 2, lining material: normal temperature Ordinary water flow detection, generally choose rubber lining; sewage treatment industry flow detection, generally choose corrosion-resistant PTFE lining; mud, mortar, mineral slurry, etc., choose wear-resistant polyurethane lining 3. Electrode material: conventional 316L stainless steel electrode; 4 , MIK-LDG electromagnetic flowmeter IP65 protection level, dustproof and rainproof standard 220V power supply, 24V optional, suitable for various occasions, standard 4-20mA output, support standard MODBUS-RTU 485 communication use and installation requirements in order to make the flowmeter The work is reliable and stable. When choosing the installation location, you should pay attention to the following requirements: a. Try to avoid magnetic objects and equipment with strong electromagnetic fields (such as large motors, large transformers, etc.), so as to prevent the magnetic field from affecting the working magnetic field and flow of the
sensor Signal b. It should be installed in a dry and ventilated place as much as possible, not in a place that is damp or easy to accumulate c. It should be avoided as far as possible from the sun and rain, and the ambient temperature is higher than 60℃ and the relative humidity is higher than 95% d. Choose for easy maintenance, Places that are convenient for movement e. The flow meter should be installed at the back end of the pump, never on the suction side; the valve should be installed on the downstream side of the flow. The location of the pipe should be installed in order to make the flow meter work reliable and stable. Pay attention to the following requirements; a. The sensor can be installed on a vertical pipe, a horizontal pipe or an inclined pipe, 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 pipe 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.
