1967年，YOKOGAWA开发了VD6振动型液体密度计以满足用户在线密度测量的需要，促进流程自动化及节省劳动力和能源，进一步改进和稳定质量。在仪器仪表领域，这是一个重要的进步，因为密度是一个基本的物理量，几乎所有的流程都需要对密度精确测量。作为稳定性好、灵敏度高的仪器，VD6型密度计赢得了良好的声誉。
DM8振动型液体密度计是在VD6的应用经验基础上，采用最新的计算机技术结合宽量程的传感器技术开发出来的高可靠性、多功能的仪器。变送器与微处理器结合，直接将传感器传送的信号转换为密度值显示出来，具有如One-touch校正、自我诊断、数字输出（RS-232-C）等多种功能。

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.
