    Description:
    District heating systems are used increasingly often when discussing heating buildings in general. Existing systems are also expanding by a number of new substations as well.

    The system itself becomes bigger and bigger and consequently the demands to control the complete system become more demanding. One of the demands is also to gain a more precise control of the flow in the system. Here Flow Controllers (together with Differential Pressure Controllers) play an important role.

    In this eLesson we will focus on the use of Flow Controllers and their role in such systems and the benefits of having them installed.



    After completing this eLesson you will be able to:

    • Understand and describe the basic functions of flow controllers
