Measuring Instruments Directive (MID)

FIB operating system and MID

The FIB Industries' operating system for beer delivery meets all the European directives and is MID certified. The combination of flowmeter/flow computer meets the Measuring Instruments Directive (MID) and is used on all control and measuring systems for liquids and gases.


New European directive for measuring instruments

Legal metrology has undergone a number of profound changes in Europe, including the introduction of the Measuring Instruments Directive (MID). This new directive applies to custody transfer metering for liquids and gases and is applicable in the 27 member states of the European Union (plus Norway and Switzerland) (also see For liquids such as beer, the MID refers to the entire installation (under the name of “measuring systems for liquids other than water”).


MID transition period and compliance

The transition period for MID compliance is 10 years. Meters or measuring systems type-approved by national metrology authorities before 30th October 2006 may be installed or used until 30th October 2016. If a modification is made to a meter or measuring system that was type-approved by a national metrology authority after 30th October 2006, the modification may lead to an extension of the existing national approval or to a new MID approval.


New meters and measuring systems

Meters and liquid systems that were designed after 30th October 2006 must be submitted for type approval under the new MID Directive 2004/22/EC. The inspections that are undergone by these new meters and systems will result in a CE mark with reference to the MID directive. Compliance with this directive is assumed when observing the OIML recommendation OIML R117-1 (measuring systems for liquids other than water).


Meters and measuring systems designed before 30th October 2006

Nationally approved meters and measuring systems installed before 30th October 2006 are not affected by the MID. They may be used until the end of their service life and remain subjected to the national legal inspections. Modifications to these meters and measuring systems do not fall within the scope of the MID. Modifications will be re-evaluated by the national metrology authority, resulting in an extension to the existing national approval or having to apply for a new MID certificate.
