MID and CE conformity
This model is included in the EU type-examination scope under Directive 2014/32/EU (MID), MI-004 thermal energy meters, Module B. The assessed series has accuracy class 2 and IP65 protection. EU type examination is one stage of conformity assessment; CE marking and the complete EU Declaration of Conformity must be evaluated with the other applicable documents.
Hydraulic selection and installation
Select the meter by actual design flow rate, approved configuration, installation dimensions and system conditions, not by pipe diameter alone. Verify the complete ordered variant using the current technical data sheet.
Remote reading
M-Bus and other communications interfaces depend on the ordered configuration. Confirm interface availability and integration with the Atlas remote reading system before ordering.
