Huikeda electromagnetic flowmeter manufacturer has been widely praised for its excellent product quality and high cost performance. The company’s main products include vortex flowmeters, sewage flowmeters, orifice flowmeters, steam flowmeters, turbine flowmeters, etc., which are widely used in industrial wastewater, cooling, and Water, water plants and other industry departments, as well as flow meter measurement in the fields of municipal management, water conservancy construction, river dredging, and building water supply measurementThe measurement principle of Huikeda electromagnetic flowmeter is based on Faraday’s law of electromagnetic induction. The measuring tube of Huikeda electromagnetic flowmeter is a short non-magnetic alloy tube lined with insulating material. Two electrodes are fixed on the measuring tube through the tube wall along the tube diameter direction. The electrode tip is basically flush with the inner surface of the lining. When the excitation coil is excited with a two-way square wave pulse, a working magnetic field with a magnetic flux density of B is generated in the direction perpendicular to the axis of the measuring tube. At this time, if a fluid with a certain conductivity flows through the measuring tube, the electromotive force E will be induced by cutting the magnetic field lines. The electromotive force E is proportional to the magnetic flux density B. The product of the tube inner diameter D and the average velocity V is measured. The electrode detects the electromotive force E (flow signal) and sends it to the converter through the cable. After the flow signal is amplified, the fluid flow is displayed, and the pulse, analog current and other signals are output for flow control and adjustment. E=kbdv
Where E is the signal voltage between the electrodes (V)Magnetic flux density (T)Inner diameter of measuring tube (m)Average speed (ms), Where K and D are constants, and B is also constant, because the excitation current is constant. It can be seen from E=kbdv that the fluid flow rate Q is proportional to the voltage signal E, that is, the signal voltage E caused by the flow rate has a linear relationship with the volume Q. Therefore, Q can be determined by measuring e, which is the basic principle of the flowmeter; it can be seen from E=kbdv that the temperature, density, pressure, conductivity and liquid-solid composition ratio of the measured fluid medium have no effect on the measurement results. As for the flow state, as long as it conforms to the axisymmetric flow (such as laminar flow or turbulent flow), it will not affect the measurement results. Therefore, the Yunnan flowmeter is a real volume flow. There is no correction. This is an outstanding feature of Yunnan flowmeter, which is not available in other Yunnan flowmeters. There are no moving and blocking parts in the measuring tube, almost no pressure loss, and high reliabilityHuikeda electromagnetic flowmeter has unique advantages and is widely used in chemical fiber, food, paper, sugar, mining, water supply and drainage, environmental protection, water conservancy, steel, petroleum and other industries, pharmaceutical and other industrial fields to measure various acids, salt solutions, Mineral pulp, mineral pulp, paper pulp, coal water slurry, corn steep liquor, fiber pulp, grain pulp, lime milk, sewage, raw cooling water, etc. for water supply and drainage, brine, hydrogen peroxide, beer, wort, various beverages, black liquor, etc., green liquor, etc. Volume flow of conductive liquid mediumFeatures of Huikeda Electromagnetic FlowmeterThere are no moving parts and blocking parts in the pipeline, and there is almost no additional pressure loss in the measurementMeasurement results and physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc.The measurement range can be modified online according to the actual needs of the userHigh-definition backlit LCD display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understandUsing SMD devices and SMT technology, high circuit reliabilityAdopt 16-bit embedded microprocessor, fast calculation speed, high precision, programmable frequency low frequency rectangular wave excitation, improve the stability of flow measurement, low power consumptionFull digital processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range up to 150:1.
