Thermal energy meters - Recommendations for circulation water in industrial and district heating systems and their operation prCEN/TR 16911 rev

Scope

This document applies to industrial and district heating supply by means of high-temperature water heating facilities (flow temperature > 100 °C). This also applies to high-temperature water heating facilities (flow temperature ≤ 100 °C) that are directly connected to district heating networks. In this document, the aforementioned supply variants will, in the following, be referred to as “district heating facilities”.

This document applies without limitations to new facilities. For existing district heating facilities, the application of this document is recommended in order to prevent faults due to the chemical composition of the circulation water that would affect the facilities' safe operability and availability.

NOTE Informative notes in the form of guidance and recommendations are identified correspondingly and
set in italics for better differentiation.
