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。
6.合理的工艺规程及正确的操作。防止在生产过程中产生的气泡流经电磁流量计。
四、涡街流量计
1.管道支架:如果管路中有振动,则应加支撑。
2.安装方面:如果管路中充满液体,则雷诺数大于2×104,则管道可作垂直安装或倾斜角度安装。
3.阀门的位置和直管段长度
A.一般情况下,把流量计安装在阀门的上游。流量前后直管长度分别为>20D和>5D。
B.把阀门安装在流量计的上游:对于使用活塞式或或罗茨式鼓风机、压缩机的空气管道或使用活塞式、柱塞式泵上午高压液体管(约大于1Mpa)可能会产生液体振动。在这些情况下,可将阀门安装于流量计的上游。此时流量计与阀门间的直管长度应大于20D,流量计下游直管长度应大于5D。
4.弯管和直管段长度:在流量上游应保证20D的直管段长度。若流量计上游安装有闸阀,则上游应保证至少20-40D的直管长度。
5.缩、扩径管和直管长度:流量计的上游应保证10D的直管长度,在下游应保证5D的直管长度。
6.测压点:把测压点取在流量计下游侧2-7D间。
7.测温点:把测温点取在测温点下游侧1-2D距离间。
