8.6.2 MID Annex III (MI-001)
All new designs of water meters that are to be used for legal purposes in Europe require
certification under the Measurement Instrument Directive (MID) 2014/32/EU Annex III (MI-001).
Annex MI-001 of the MID applies to water meters intended for the measurement of volume of
clean, cold or heated water in residential, commercial and light industrial use. An EC-type
examination certificate is valid in all countries of the European Union.
The WATERFLUX 3070 has an EC-type examination certificate and can be verified to the MID
Annex III (MI-001) for water meters with diameter DN25...DN600. The conformity assessment
procedure followed for WATERFLUX 3070 is Module B (Type Examination) and Module D (Quality
Assurance of the Production Process).
The maximim permissible error on volumes delivered between Q2 (transitional) flow rate and Q4
(overload) flow rate is
±
2%.
The maximum permissible error on volumes delivered between Q1 (minimum) flow rate and Q2
(transitional) flow rate is
±
5%.
Refer to the technical datasheet of WATERFLUX 3070 for further details of the certification.
Q1 = Q3 / R
Q2 = Q1 * 1.6
Q3 = Q1 * R
Q4 = Q3 * 1.25
