What are the advantages of electromagnetic flow meters?
In the selection of imported flow meters, it is important to be clear about the characteristics of each flow meter, including its advantages and disadvantages. It is not just about looking at the advantages of the flow meter. As engineers from the well-known imported flow meter brand VTON in the United States have pointed out, every product has its own disadvantages. Therefore, it is necessary to choose a suitable imported flow meter based on its advantages and disadvantages, and avoid choosing an unsuitable flow meter; Lets first analyze the advantages of imported electromagnetic flow meters. Please click on the image to describe the advantages of the imported electromagnetic flowmeter. (1) There is no obstruction in the measuring tube, zero pressure loss, and it is not easy to block.
(2) As long as reasonable electrodes and village materials are selected, the requirements for corrosion resistance and wear resistance can be achieved. For example, the imported electromagnetic flowmeter from the US Weidun VTON mainly uses acid resistant steel and molybdenum containing acid resistant steel, Hastelloy B, Hastelloy C, platinum iridium alloy, and tantalum as electrode materials, and F40 and F46 fluoroplastics as lining materials. (3) The measurement results are basically independent of physical parameters such as pressure, temperature, density, viscosity, and conductivity (not less than the minimum conductivity of 5 μ S/cm) of the liquid, and are not affected by the environment. Therefore, the measurement accuracy is high, the work is stable, and reliable. (4) Adopting the latest analog signal technology and high-performance ultra large scale integrate
(5) can be used for measuring large-diameter pipelines. For example, the imported electromagnetic flowmeter from VTON in the United States is used for DN450-800 pipelines.
(6) Automatic monitoring and correction of parameters that affect measurement results, setting and correcting segmented flow coefficients for the entire range, thus expanding the measurement range, improving intelligence and measurement accuracy, and greatly enhancing stability performance.
(7) It has air tube protection, measurement value power-off protection, and over range alarm function. The sensor installation is not limited by the direction of liquid flow and can achieve bidirectional flow measurement.
(8) Adopting a backlit dot matrix dual row flow display, it can simultaneously display instantaneous flow, cumulative flow, and display working status, parameters, measurement units, etc. (9) The range is wide, with a normal application range of 20:1 and generally 30:1 or greater.
2. Which flowmeter is more stable?
3. Range of intelligent electromagnetic flowmeter
Generally, the flow rate of the measured medium in industrial electromagnetic flowmeters should be 2-4m/s. In special cases, the minimum flow rate should not be less than 0.2m/s and the maximum should not be greater than 8m/s. If the medium contains solid particles, the flow velocity of the commonly used drying agent should be less than 3m/s to prevent excessive friction between the lining and the electrode; For viscous fluids, the flow velocity can be chosen to be greater than 2m/s. A higher flow velocity helps to autom
