西门子电磁流量计，7me系列 上海代理折扣订购

zui适宜的流量计
为特定的应用而使用zui适宜的流量计能显著地提升生产率。这就是为什么西门子提供广泛的电磁、科里奥利、超声波、涡街、旋转活塞和差压流量计的选择。不过您所有应用的是什么工业，我们都能给您提供理想的流量计。

电磁流量计是为供水企业水计量贸易专门设计的，具有防水、防腐、防干扰、防雷击的能力。
电磁流量计特别设计了带背光宽温的中文液晶显示器，功能齐全实用、显示直观、操作使用方便，可以减少其他电磁流量计英文菜单所带来的不便。另外我们*设计4-6多电极结构，进一步保证了测量精度并且任何时候无需接地环，减轻了仪表体积和安装维护的麻烦。 
电磁流量计
电磁流量计在满足现场显示的同时，还可以输出4～20ma电流信号供记录、调节和控制用，现已广泛地应用于化工、环保、冶金、医药、造纸、给排水[1]等工业技术和管理部门。 采用电磁感应原理测量介质流体流速的电磁流量计。它在管道的两侧加一个磁场，被测介质流过管道就切割磁力线，在两个检测电极上产生感应电势，其大小正比于流体的运动速度。可以用于测量酸、碱、盐溶液、水煤浆、矿浆、砂浆灰泥、纸浆、树脂、橡胶乳、合成纤维浆和感光乳胶等各种悬浮物、气化汽和粘性物质的流量。电磁流量计密封性能好，还可用于自来水和地下水道系统。而且测量过程不与流体接触，适于制药、生物化学和食品工业。这种流量计还可检测血液流量。它的量程比约为100:1，精度一般为1％，由于这种传感器必须保持管道内电阻和测量电路阻抗之间有一定比例关系，因此在制造上有一定困难。当被测介质的电导率约为10欧姆·厘米时就开始产生困难，电导率更低时就产生原理性困难。当电导率为10欧姆·厘米时，就达到导电介质和电介质之间的“分界线"，热噪声电平随内阻的增大而显著增加。
  电磁流量计是高精度、高可靠和使用寿命长的流量仪表，所以在设计产品结构、选材、制定工艺、生产装配和出厂测试等过程中每一个环节我们都非常细致讲究，还自行设计了一套中国的，于电磁流量计的生产设备和流量实流标定装置，从而在软件和硬件上都能切实保证产品*的高质量。电磁流量计特别设计了带背光宽温的中文液晶显示器，功能齐全实用、显示直观、操作使用方便，可以减少其他电磁流量计英文菜单所带来的不便。另外我们*设计4-6多电极结构，进一步保证了测量精度并且任何时候无需接地环，减轻了仪表体积和安装维护的麻烦
