注意-零件可能受损！

静电可能会损坏印刷电路板的电子元件

（请遵守ESD指南）。确保你体内的静电被释放

当接触电子元件时。

10.1流量计传感器

流量计传感器基本上不需要维护。以下项目应

每年检查一次：

•环境条件（空气循环、湿度）

•工艺连接的密封完整性

•电缆入口点和盖螺钉，

•辅助馈电、防雷和接地的运行可靠性

当流量计上的流量信息

变送器在记录相同流量时发生变化。如果显示器显示更高

流量，污染物是绝缘的。如果显示的流量较低，则污染物

导致短路。

对于衬里、电极或电磁线圈的维修，流量计必须返回到本地

ABB公司办公室。

重要（通知）

将流量计传感器发送到ABB当地办事处时，请填写

附件，并随设备一起提供。

清洁仪表外部时，确保使用的清洁剂不会腐蚀

外壳表面和垫圈。

Attention - Potential damage to parts!

The electronic components of the printed circuit board can be damaged by static electricity 

(observe ESD guidelines). Make sure that the static electricity in your body is discharged 

when touching electronic components.

10.1 Flowmeter sensor 

Essentially maintenance is not required for the flowmeter sensor. The following items should be 

checked annually:

• Ambient conditions (air circulation, humidity)

• Seal integrity of the process connections

• Cable entry points and cover screws,

• Operational reliability of the auxiliary power feed, the lightning protection and the grounds

The flowmeter sensor electrodes must be cleaned when the flowrate information on the 

transmitter changes when recording the identical flowrate volume. If the display shows a higher 

flowrate, the contamination is insulating. If the flowrate displayed is lower, the contamination 

results in a short-circuit.

For repairs to the lining, electrodes or magnet coil, the flowmeter must be returned to the local 

office of ABB.

Important (Notice)

When sending the flowmeter sensor to the local office of ABB, complete the return form in the 

appendix and include with device.

When cleaning the exterior of meters, make sure that the cleaning agent used does not corrode 

the housing surface and the gaskets.
