Requirements for installing electromagnetic flowmeters in industrial pipelines

  在工业管道中装置电磁流量计 有哪些要求 What are the requirements for installing electromagnetic flowmeters in industrial pipelines ?
电磁流量计 调试 First, the debugging of electromagnetic flowmeter
 
零碎调试 Fragmented debugging
    
零碎调试 时,必须满足两个条件: a . 油性介质管道 实行枯燥前 方可通入被测介质 ,进行 零碎运转 b . 电磁流量计在实行完单项通水测试,控制主机各项预备调试完成后,可 进行 零碎调试。 During the piecemeal commissioning , two conditions must be met: a . Before the oily medium pipeline is boring , the measured medium can be passed in for fragmentary operation ; b . The electromagnetic flowmeter has completed a single water test to control the host After the pre-commissioning is completed, the system can be debugged fragmentarily.

零碎调试时 的步骤: 主机零碎 对各个测量点实行编码扫描 ,保证各仪表部件在正常状态下,进行 功效性调试 Steps in piecemeal commissioning : ⑴The host machine performs code scanning on each measurement point to ensure that the instrument components are debugged in a normal state . 功效性调试 先由 主机零碎各仪表 参数 进行读取,然后进行逐一调试。 ⑵Effectiveness debugging reads the parameters of each instrument by the host , and then debugs one by one.
仪表终端单体PLC 编程 进行调试。 After the above work is completed, the instrument terminal single PLC programming can be debugged.
  
调试前 的准备工作 Preparation before commissioning

管道 流量计 电气线路 进行 彻底检验 Before commissioning, thoroughly inspect the pipes , flow meters and electrical wiring . 绝缘电阻 接地电阻 进行 测试 After these inspections, the insulation resistance and ground resistance need to be tested .

通水调试 Water debugging
   
还是测油性介质的仪表 ;都要实行通水调试。 Regardless of whether it is an instrument for measuring water-based media or oil-based media ; water-through debugging is required.

结束 后, 还要继续测量,观察测量的数据情况。 After commissioning , continue to measure and observe the measured data. 牢靠 性和稳定性,那么就可以进行 零碎预验收 了。 If the measured data is reliable and stable, then piecemeal pre-acceptance can be performed .
