本标准描述了用于在线监测冷却水系统中污垢、腐蚀和其他参数的各种设备。详细介绍了收集测试数据以确定污垢和腐蚀速率的方法，这些方法可用于实时处理不断变化的条件。它还包括环形和管状流动示意图以及集成在线监测器的图示。本标准由任务组241维护。

This standard describes a variety of devices used for online monitoring of fouling, corrosion, and other parameters in cooling water systems. Detailed are methods for collecting test data to determine fouling and corrosion rates that may be used to deal with changing conditions in real time. It also includes figures illustrating schematics of annular and tubular flow and integrated online monitors. This standard is maintained by Task Group 241.
