What is PD CEN/TR 16911-Heat meters about?
PD CEN/TR 16911 discusses heat meters. PD CEN/TR 16911 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 PD CEN/TR 16911, the supply variants will, in the following, be referred to as “district heating facilities”.
PD CEN/TR 16911 applies without limitations to new facilities. For existing district heating facilities, the application of PD CEN/TR 16911 is recommended to prevent faults due to the chemical composition of the circulation water that would affect the facilities' safe operability and availability.
