1.电池供电电磁流量计由传感器和转换器两部分构成。它是基于法拉第电磁感应定律工作的，用来测量电导率大于5μS/cm导电液体的体积流量，是一种测量导电介质体积流量的感应式仪表。除可测量一般导电液体的体积流量外，还可用于测量强酸强碱等强腐蚀液体和泥浆、矿浆、纸浆等均匀的液固两相悬浮液体的体积流量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（如图所示）基于法拉第电磁感应定律:E=K*B*D*V,其中E是感应电动势;K是仪表常数;B是磁感应强度;D是测量管直径;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）只能测量导电介质 Only conductive media can be measured

电导率限制条件6≥1-5uS/cm(水>20uS/cm)(低电导率>0.05uS/cm使用仪表) Conductivity limit condition 6 ≥ 1-5uS/cm (water>20uS/cm) (low conductivity>0.05uS/cm using dedicated instruments)原理及用途.jpg

不能测量非导电介质，如气体，油类，如介质含有大量气体，产生测量严重波动 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）必须存在磁场 Magnetic field must be present

励磁电流流经测量管上下励磁线圈产生磁场。励磁线圈断路，流量计不工作，励磁电流稳定性直接影响仪表测量 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

测量管必须为非导磁材料，保证磁场穿过导管(测量管应采用不锈钢材质) 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）实际测量值为流体流速 The actual measured value is the fluid flow rate

电磁流量计实际测量介质的流速(它是速度式流量计) Electromagnetic flowmeter actually measures the flow rate of the medium (it is a velocity type flowmeter)
