供水法规定的淡水分配系统中自来水的游离氯含量为O.lmg/l左右。然而，过量的有效游离氯存在会导致水不新鲜，超过1mg/l的游离氯据报道对人体有害。因此，用游离氯分析仪测量和监控供水系统中的游离氯含量近年来变得越来越重要。
FC400G无试剂型游离氯分析仪采用极谱分析方法，用旋转电极连续测量在线游离氯的浓度。
FC400G是一种以微处理器为基础的，真正智能化的游离氯分析仪，它集中了YOKOWA公司在余氯分析仪上的长期经验。
商用的FC400G的主要特点是维修方便和不使用试剂。

system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
Freelance 800F DigiVis Operator Level
DigiVis operator stations use PC hardware, either standard commercial
Business PCs can also be industrial-grade PCs and run on Micro-
under soft Windows operating system. DigiVis supports dual-screen display operation
operating technology, that is to say, two operations can be performed using one PC
station and operate with a mouse and a keyboard.
Operator level can install one engineering station and several operators
stand. ControlBuilderF engineering station configures and adjusts the system
Mode. Usually, we can use portable devices such as notebooks to
The system is now configured in the office and on site. Operator-level PC
Can also be used as an engineer station. Engineer standing during system uptime
Intervals can be closed without a permanent connection to the system.
Freelance 800F Process Control Stage
At the process control level, the Freelance 800F system can be controlled by
It consists of a number of process control stations connected to I/O units. you can choose this
Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy
redundant) or non-redundant mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
AC800F controller connects remote I/O or field device via fieldbus
ready.
system communication
Communication between operator level and process control level using TCP/IP
Protocol system bus (based on Ethernet), you can choose different
transmission medium such as AUI, twisted pair, fiber optic or coaxial cable.
