1.安装位置的环境条件（温度、湿度、电磁场等）必须符合说明书要求。
2.直管段长度。根据流量计所在管道的情况，必须保证必要的直管长度，一般上游管道保持10D以上直管段，下游保持3D-4D。D为管道直径。
3.化学添加剂的加入会影响液体电导率，不应在仪表上游注入，如必须在上游注入则必须保持足够容积的反应器或直管段，使流经流量计的液体电导率已处于稳定状态。
4.安装方式：无论水平、垂直、倾斜安装均必须保证仪表测量管中始终充满液体且无气泡存在（参见仪表说明书）。对于含有固体颗粒或浆液建议垂直安装，流向由下向上。电极所在平面必须与地面平行。

5.接地
A.流量传感器的工作接地是保证基准电位与被测体相同，而液位电位又应与地电位相同。电磁流量计配有接地环，其作用是通过与液体接触，建立液体接地。根据流量计所在管道材料的不同，正确采用接地连接方式。工作接地应坚持“单点接地”原则。（参见“化工自动化及仪表”1998年第四期48-49页“电磁流量计的接地措施”一文）接地电阻应≤100欧姆。
B.屏蔽接地。从流量转换器输出至二次仪表DCS系统的信号电缆，其屏蔽层接地在控制室一侧，通过接地汇流排接地。位置
A.变送器的安装位置应避免机械损伤和振动。电子单元应安装在阴凉透风处，并且防止防浆，建议再其上面安装防水挡板。
B.变送器应尽量靠近稀释水连接处的测量点安装，保证**短时间迟滞。
C.变送器可安装在垂直、水平浆管上。垂直位置变送器应与泵的轴线垂直，水平位置应安装在浆管的侧面。建议尽可能安装在垂直位置。
2.距离
A.变送器的安装位置应考虑前后浆管**小稳定距离L1、L2。一般情况下，L1=10D、L2=5D、D—管径。也可以根据实际流量和浓度，利用仪表使用说明书附图估计L1的长度，L2=L1×0.3+0.3。
B.该估算方法适用于化学浆及长纤维浆。若是废纸浆、磨木浆以及短纤维浆。上述估计的结果再乘以1.25。
