Measuring Instruments Directive (MID)
Measuring Instruments Directive (MID) MID/EN14154 Short Overview
STARTING POSITION Approval vs. Type examination In the past, country specific approvals were needed to sell measuring instruments in EU For the future, only one type examination certificate acc. the new Measuring Instrument Directive (MID) for the EU 26. Juli 2013
MEASURING INSTRUMENT DIRECTIVE Facts & Figures Scope includes. .water meters (MI-001) .gas meters (MI-002) .electricity meters (MI-003) .heat energy meters (MI-004) .etc. Needed for measuring instruments, where levying of consumption takes place within the EU All these measuring instruments are covered by the EU directive 2004 / 22 / EC Measuring instruments acc. MID calls from now. .«Product name» with CE Conformity (MID) Declaration of CE conformity
STARTING POSITION Goal The main goal for the definition and introduction of the new measuring instrument directive was the reduction of trade barriers within the European countries. Validation period Instruments approved before 30th October 2006 may continue to be sold for up to 10 years Country specific approvals Oct. 30th 2006 Overlapping period 10 years Oct. 30th 2016 Type examination acc. MID New meters have to comply as from 30th October 2006
Harmonized norms and certification EU members under the MID Austria Poland Belgium Portugal Bulgaria Slovenia Cyprus Slovakia Denmark Spain Estonia Sweden France United Kingdom Finland The Netherlands Germany Switzerland Greece Hungary Italy Ireland Latvia Lithuania Luxemborg Malta (Bilateral Agreements)
What is required of the manufacturer? All new meters require a approval of the instrument (Type examination certificate (CH-MI004-07003-00)) Audit of the production plant before instrument can be sold Must issue a conformity declaration Instrument must be marked in accordance with the directive
The MID Certification does away with the following: MID PTB Type approvals EEC approval Local European certification (country specific)
Marking of measuring instruments according to MID Number of the certified calibration centre M 08 CE - Marking 0862627 6 Metrology – Identification and manufacture year Manufacturer Serial Number
Markings MI - 001 Cold Water Meters
Markings MI-001 Consumption Meters Unit of measurement: cubic metre Numerical value of Q3 Ratio Q3 / Q1 , preceded by “R” Ratio Q2 / Q1 , where it differs from 1,6 (during transition period) Maximum admissible pressure if it differs from 10 bar (1 MPa) Direction of flow Letter V or H, if the meter can only be operated in the vertical or horizontal position Temperature class, where it differs from T30 Pressure loss class, where it differs from DP 63 Classes on sensitivity to irregularities in velocity field
Markings MI-001 Name or trademark of the manufacturer Year of manufacture (first 2 digits) and serial number Pattern approval sign according to European regulations Climatic and mechanical environment severity level EMC Class Output signals for ancillary devices (type/levels) if any

or end measurements. In end measuring instruments, the measurement is taken between two end surfaces as in micrometers, slip gauges etc. The instruments used for linear measurements can be classified as: 1. Direct measuring instruments 2. Indirect measuring instruments The Direct measuring instruments are of two types: 1. Graduated 2. Non Graduated
