Advantages and disadvantages about the intelligent electromagnetic flowmeter
With the vigorous development of the domestic economy, used in the industrial production in measuring instrument is also constantly innovation, various types, various types of industrial instrumentation, intelligent electromagnetic flowmeter is widely used among varieties, industrial use very wide range of the calibre of the intelligent electromagnetic flowmeter, from a few millimeters to meter, adapt to all kinds of diameter specifications have, henan cisco measurement and control technology co., LTD has diameter up to 2 m the efficacy of the facilities, it has been widely used in industrial production. Through intelligent electromagnetic flow meter in recent years, constantly updated, has many advantages, summarized has the points:
1. The intelligent electromagnetic flowmeter is a kind of volume flow measuring instrument, in the process of concrete measure, it can be not affected by the temperature of the measured medium, with the influence of the conductivity, viscosity and density measure stability effectively. So, the intelligent electromagnetic flowmeter only after water calibration, can be safely used to measure the rate of flow of other conductive liquids.
2. The intelligent electromagnetic flowmeter can measure the corrosive throttling, polluted medium, including suspension solid two phase flow of traffic is a cinch. This is because the average measurements of the interior of the tube may not hinder the medium flow components, and the flow of militant only sounding pipe lining and electrode, with all the material can choose according to the measured medium. Adopt wear-resisting rubber lining, for example, is particularly suitable for measuring with solid particle slurry, water slurry, wear a large liquid-solid two phase flow and various suspension body, such as fiber and pulp with teflon or three do lining fluoride, can measure all kinds of acid, alkali, salt and other corrosive medium
3. The internal structure of the intelligent electromagnetic flowmeter is simple, the measuring tube without any obstacles to fluid flow throttling components, no moving parts. So when the fluid flow through timing does not cause any additional pressure loss, the intelligent electromagnetic flowmeter run one of the lowest energy consumption flow meter.
4. The intelligent electromagnetic flowmeter responsive, no mechanical inertia, not only can measure the instantaneous pulse flow, also can measure the rate of flow of positive and negative two direction.
5. Because the output of the intelligent electromagnetic flowmeter has nothing to do with symmetrical distribution of flow state, only proportional to the average flow velocity of the measured throttling, so the intelligent electromagnetic flowmeter range is very wide range, the measurement range can be up to 100:1, or even 1000:1 working flow range.
The intelligent electromagnetic flowmeter advantages particularly evident, however, is not a perfect product in the world, including the intelligent electromagnetic flowmeter, only advantage, also has shortcomings, for example, to this, we also need to understand, so about the intelligent electromagnetic flowmeter deficiency analysis is as follows:
(1) low intelligent electromagnetic flowmeter can't be used to measure the conductivity of liquid medium, such as petroleum products or organic solvent such as medium, the intelligent electromagnetic flowmeter is powerless.
(2) the ordinary industrial intelligent electromagnetic flowmeter lining materials and electrical insulation of the measuring tube material limit, cannot be used to measure high temperature medium; If without special treatment, also cannot be used for the measurement of low temperature medium, in order to prevent the frost damage insulation outside the measuring tube.
(3) the intelligent electromagnetic flowmeter can't be used to measure gas, steam, and contains a lot of gas liquid.
(4) the intelligent electromagnetic flowmeter is easily affected by external electromagnetic interference.
Above about the intelligent electromagnetic flowmeter is introduced in detail the advantages and disadvantages of, only a clear understanding of the intelligent electromagnetic flowmeter the advantages and disadvantages, in order to better use in the process of industrial production, to ensure that the service life of the intelligent electromagnetic flowmeter, the hope can for the user interface for reference.
