GE 推出了 Sentinel LNG，这是高级超声波流量计系列的新增成员。Sentinel LNG以可靠的技术为基础，具有全新的性能水平，能够以难以置信的速度和精度针对流量变化做出反应。Sentinel LNG 将超声波技术的使用扩展到测量液化天然气 (LNG) 的低温应用场合，具有无与伦比的性能、可靠性和安全性。
Sentinel LNG 采用的设计原理非常简单，即安装一只可靠的流量计来克服LNG 罐的液位测量精度限制。Sentinel LNG 是一款采用无可动部件的全焊接结构超声波流量计。超声波传感器安装在低温液体的外部，从而避免因温度而引起的传感器性能的退化。设计为全通径设计，因此，仪表上的压降只等于等长管段的压降。
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.
Freelance OPC server for connecting to higher-level operators
station (800xA) or other OPC client. Freelance Control System
Real-time process values ??and alarms in the system can be accessed via OPC.
We also provide a C language programming interface to embed external
In Windows operating system applications, it is suitable for implementing user
Communicate with non-standard OPC, ie DMS-API software package.
Project database
All configured signals, variables and process points are in Freelance
800F system’s public database for management.
● List of all variables (input, output, internal variables)
● Process point list (function block)
