The inside of the measuring tube is completely open, allowing the fluid to flow unhindered through the measuring tube.Function:The magnetic inductive flow sensor functions according to the induction principle. A DC voltage is generated by the movement of a conductor in a magnetic field:The measuring tube of the FMG90B is located in a magnetic field (B).An electrically conductive medium (V) flows through the measuring tube. The positive and negative charge carriers are oppositely deflected.A voltage (U) is generated at right angles to the magnetic field, which is picked up by the two electrodes.Thereby, the induced voltage is proportional to the average flow velocity of the liquid.The electronics of the FMG90B converts the induced voltage into a flow-proportional frequency signal.FMG90B Series Installation of FMG90BTechnical changes reserved - 9 -4 Installation of FMG90BBefore installing, check that❒ the wetted materials of the device are suitable for the media being used( § 9 “Technical data”).❒ the equipment is switched off and is in a safe and de-energized state. ❒ the equipment is depressurized and has cooled down.SUITABLE TOOLS:Use only suitable tools of the correct size.4.1 Installation instructionsCAUTION! Risk of malfunction due to external magnetic fields! Magnetic fields close to the device can cause malfunctions and should be avoided.Ensure that no external magnetic fields are present at theinstallation site of the FMG90B.•The FMG90B can always be installed anywhere along the pipeline.

由于K为常数,励磁电流是恒流的,故B也是常数,则由(2-1)式可知,体积流量Q与信号电压E成正比,即流速感应的信号电压E与体积流量Q成线性关系。因此,只要测量出E就可确定流量Q,这就是电磁流量计的基本工作原理。

综述
智能电磁流量计是经过不断升级改良的高精度、高可靠性产品,该流量计在励磁技术,内衬技术,
1.1 概述 智能化技术方面达到了国内先进水平。适用于测酸、碱、盐溶液、泥浆矿浆、纸浆、废水等导电介质的 体积流量。 智能 BFC090-B 电磁转换器与 BFG-S 型电磁变送器配套成电磁流量计在结构上可分为一体型和 分体型两种,一体型电磁流量计是以传感器为结构主体将转换器(圆表)安装在传感器上成为一体,分 体型电磁流量计的传感器与转换器(方表或圆表)为各自独立结构,转换器可安装在离传感器 200m 以 内的场所。转换器壳体内分为两腔,将电气部分与周围隔开以便接线。转换器接通 220V 50Hz 电源后, 通过励磁电缆向传感器提供低频三值矩形波的励磁电流,当导电流体(被测介质)流经传感器,经转换 器处理后可显示出瞬时流量(m3/h)和累积流量(m3/h)转换器可同时输出 4~20mA DC,0~2K Hz 标准信 号,也可以通过 PS-485 与上位计算机通讯。 所有仪表在出厂前,都按用户订货时提出的量程,用水进行实流标定,量程设定都已调整完毕。用 户除检查零位外,不需任何调整,即可投入使用。若试运行时发生问题,请与本公司联系。 1.2 测量原理 测量原理是基于法拉第电磁感应定律。即:导电液体在磁场中作切割磁力线运动时,导体中 产生感应电压,其感应电压为: U=DBvD K=仪表常数 B=磁感应强度 v=测量管截面内的平均流速 D=测量管的内直径 测量流量时,流体流过垂直于流动方向的磁场,导电性液体 的流动感应出一个与平均流速(亦即体积流量)成正比的电压, 因此 要求被测的流动液体具有最低限度的电导率。其感应电压信号通 过二个与液体直接接触的电极检出,并通过电缆传送至放大器, 然后转换成统一输出信号。这种测量方式具有如下优点: 1. 测量管内无突出件,因此无附加压力损失。 2. 由于信号在整个充满磁场的空间中形成,它是管道截面上 的平均值,因此,从电极平面至传感器上游端平面间所需直管段 相对较短,长度为 5×DN(DN 为导管的内直径)。 3. 只有管道衬里和电极与被测液体接触,因此,只要合理选 择电极及衬里材料,即可达到耐腐蚀、耐磨损的要求。 4. 传感器信号是一个与平均流速成精确线性关系的电压。 5. 测量结果与流速分布及液体的压力、温度、密度、粘度、电 导率(不小于最低电导率)等物理参数无关,所以测量精度高,工作可靠。
满量程流速 V≥0.3m /s 在 20~100%流量之间 为测量值的±1% 在 0~20%流量之间 为满量程的 0.2%

装
安装之前应阅读本说明书。 安装地点必须满足本 仪表的环境条件、防护等级和便于维修要求。 3.1 安装要求 1. 仪表可以在运行管道上的任何位置安装, 优先 选用垂直安装。在水平或倾斜安装时,则两电极的轴 线必须处于水平位置(如右图) 2. 若液体流动方向与铭牌箭头指向一致, 则输出 信号的极性如接线图所示。 相反的流动方向会引起相 反的极性。 3. 要求测量管内完全充满液体, 不允许有非满管 现象。 4. 不应有铁磁性物质紧靠仪表, 仪表安装位置应 尽量远离强电磁场。 5. 仪表在上游 5DN(传感器的内直径)距离内不 能有扰流件。挡板、阀门或滑阀应安装在至少离传感 器下游侧 2DN 处。 6. 带法兰的阀门也不能直接连接在传感器的前 面或后面。因为阀门也会造成流体扰动,增加测量误 差,所以在任何情况下都不允许这样直接安装。 7. 安装时要保持密封件、 接地环与传感器的测量 管处于同心位置,避免发生旋涡流。 8. 在搬运吊装仪表时, 切忌用管或捧套入测量管

内或用绳索穿过测量管吊装,避免损坏衬里。而应将绳索套在测量管的颈部处吊装。 在介质严重污染情况下,仪表安装在旁路管道上。 这种安装方式可以不需要中断运行而打开阀门 2, 用机械 方法清洗。
3.2 接地 接地系统为 BFC090-B,BFG-S 电磁计流量器提供保护,因此仪表必须接至一个独立的接地点,其 它电气设备不允许连接到同一接地线上。接地电阻应小于 10Ω。 A. 仪表安装在内部无漆或没有衬里的金属管道上时, 可将接地导线接到两个管道法兰上, 因而形成 管道与液体的可靠接触。
