ABB质量流量计FCM2000的数据采集

ABB Mass Flowmeter FCM2000 Data Acquisition

通过ABB公司的FCM2000质量流量计的使用,介绍了利用变送器组态端口,在HART协议基础上,将4-20mA电流信号经过HART适配器解调成计算机可以识别的数字信号,通过RS485/RS232转换器引入计算机,提供流量计数据采集问题的方法。

In this paper,by ABB Mass Flowmeter FCM2000’s use,introduced the method that make use of the transmitter configuration port,based on HART protocol,pass a HART adapter changed the 4-20mA current signal into the digital signal that the computer can recognize,and then through the RS485 / RS232 converter into the computer,solved the Flowmeter da-ta collection problems.
