本液位测量产品手册用作各行业液位测量项目的用户指南。液位测量产品是一个较为宽泛的概念，单凭一本书无法全面说明，但我们的目标是尽量纳入用户最为关注的信息。
在文中，我们还罗列了一些液位测量应用，虽然不尽全面，但用户可以类似应用作为自己应用的指导。
请记住，在选择合适的液位测量设备时，决定权始终属于用户，这些指导说明仅是我们根据多年经验所作出的推荐。如果您无法作出决定，请联系您当地的艾默生销售代表。
第 1 章 – 液位测量，对液位测量进行了概述。本章节描述了液位测量的不同原因，并解答了一些用户在挑选液位测量设备时可能存疑的问题。
第 2 章 – 液位测量技术，列举了一系列市场中现有的液位测量技术。在本章节中，我们对测量技术和原理进行了描述，并说明了各项技术的优势和局限。其原因在于，对于大部分应用来说，市面上尚无任何一种技术能够满足其所有要求。不同的过程条件、测量介质以及用户的偏好都将影响技术的最终选择。
第 3 章 – 罗斯蒙特液位测量产品， 概述了罗斯蒙特过程液位测量产品。
第 4 章 – 液位测量应用与技术选择，从本章开始介绍具体的液位测量应用。本章节中所选择的应用旨在为不同类型应用提供范例，并未涵盖所有可能发生的情况。这是为应用选择合适的液位测量设备的第一步。本章列举了各类应用的适用技术。
第 5 – 10 章，安装指南，详细说明了各项液位测量技术的安装注意事项。
第 11 章 – 全套解决方案，涵盖了如何选择和确定导波雷达和旁通管的尺寸，以达到完美的安装效果。
第 12 章 – 法兰及材料，解释说明了用户所需的法兰及其材料信息。
第 13 章 – 产品批准和产品认证，对不同标准进行了概述。
第 14 章 – 安全回路，说明了安全回路的重要性，并解释了应用验证和认证之间的区别。
第 15 章 – 参考材料，包含转换表、不同介质的介电常数、蒸汽表、液位测量术语等参考信息，并对一系列最常见的问题进行了解答。
第 16 章 – 文档，包含支持文件。这些技术说明和白皮书说明了如何成功应对液位测量带来的挑战，以及其他用户使用罗斯蒙特液位测量技术的范例。

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)
●Graphics
●Program
Because the database is system-wide. The data only needs to enter a
times, to avoid possible errors caused by multiple configurations.
Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL
Revise.
List other features include:
Project-wide modification of names, comments, data or module types
●Search and display based on specific criteria
● Cross reference can be used in systems that use a large number of variables or process points
Programs and drawings to quickly find the desired variable or process point within the scope
