1.電池供電電磁流量計由傳感器和轉換器兩部分構成。它是基于法拉第電磁感應定律工作的，用來測量電導率大于5μS/cm導電液體的體積流量，是一種測量導電介質體積流量的感應式儀表。除可測量一般導電液體的體積流量外，還可用于測量強酸強堿等強腐蝕液體和泥漿、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定律:E=K*B*D*V,其中E是感應電動勢;K是儀表常數(shù);B是磁感應強度;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）只能測量導電介質 Only conductive media can be measured

電導率限制條件6≥1-5uS/cm(水>20uS/cm)(低電導率>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

不能測量非導電介質，如氣體，油類，如介質含有大量氣體，產生測量嚴重波動 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

勵磁電流流經(jīng)測量管上下勵磁線圈產生磁場。勵磁線圈斷路，流量計不工作，勵磁電流穩(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

測量管必須為非導磁材料，保證磁場穿過導管(測量管應采用不銹鋼材質) 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）實際測量值為流體流速 The actual measured value is the fluid flow rate

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