：RETZ/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)口鋰電池供電電磁流量計(jì)原理及用途Principle and purpose

1.電池供電電磁流量計(jì)由傳感器和轉(zhuǎn)換器兩部分構(gòu)成。它是基于法拉第電磁感應(yīng)定律工作的，用來測量電導(dǎo)率大于5μS/cm導(dǎo)電液體的體積流量，是一種測量導(dǎo)電介質(zhì)體積流量的感應(yīng)式儀表。除可測量一般導(dǎo)電液體的體積流量外，還可用于測量強(qiáng)酸強(qiáng)堿等強(qiáng)腐蝕液體和泥漿、礦漿、紙漿等均勻的液固兩相懸浮液體的體積流量retz The battery powered electromagnetic flowmeter consists of a sensor and a converter. It is d on Faraday's law of electromagnetic induction and is used to measure electrical conductivity greater than 5 μ The volume flow rate of S/cm conductive liquid is an inductive instrument for measuring the volume flow rate of conductive media. In addition to measuring the volume flow rate of general conductive liquids, it can also be used to measure the volume flow rate of strong corrosive liquids such as strong acids and alkalis, and homogeneous liquid-solid two-phase suspension liquids such as mud, pulp, and pulp

2.基本原理（如圖所示）基于法拉第電磁感應(yīng)定律:E=K*B*D*V,其中E是感應(yīng)電動(dòng)勢;K是儀表常數(shù);B是磁感應(yīng)強(qiáng)度;D是測量管直徑;V是平均流速 The basic principle (as shown in the figure) is d on Faraday's law of electromagnetic induction: E=K * B * D * V, where E is the induced electromotive force; K is the meter constant; B is the magnetic induction strength; D is the diameter of the measuring tube; V is the average flow rate

（1）只能測量導(dǎo)電介質(zhì) Only conductive media can be measured

電導(dǎo)率限制條件6≥1-5uS/cm(水>20uS/cm)(低電導(dǎo)率>0.05uS/cm使用儀表) Conductivity limit condition 6 ≥ 1-5uS/cm (water>20uS/cm) (low conductivity>0.05uS/cm using dedicated instruments)原理及用途.jpg

不能測量非導(dǎo)電介質(zhì)，如氣體，油類，如介質(zhì)含有大量氣體，產(chǎn)生測量嚴(yán)重波動(dòng) Unable to measure non-conductive media such as gases and oils, such as media containing a large amount of gas, resulting in severe fluctuations in measurement

（2）必須存在磁場 Magnetic field must be present

勵(lì)磁電流流經(jīng)測量管上下勵(lì)磁線圈產(chǎn)生磁場。勵(lì)磁線圈斷路，流量計(jì)不工作，勵(lì)磁電流穩(wěn)定性直接影響儀表測量 The excitation current flows through the upper and lower excitation coils of the measuring tube to generate a magnetic field. The excitation coil is open circuit, the flowmeter does not work, and the stability of the excitation current directly affects the instrument measurement

測量管必須為非導(dǎo)磁材料，保證磁場穿過導(dǎo)管(測量管應(yīng)采用不銹鋼材質(zhì)) The measuring tube must be made of non magnetic conductive material to ensure that the magnetic field passes through the tube (the measuring tube should be made of stainless steel)

（3）實(shí)際測量值為流體流速 The actual measured value is the fluid flow rate

電磁流量計(jì)實(shí)際測量介質(zhì)的流速(它是速度式流量計(jì)) Electromagnetic flowmeter actually measures the flow rate of the medium (it is a velocity type flowmeter)
