1. MID - General

European CE Directive (2004/22/EC), published in the Official Journal of European Communities on 30 April 2004 (nr. L135)

Effective per 30 Oct 2006 with a transition period up till 30 Oct 2016 for the “unchanged” instrument (amendment to national approval not possible !!)

MID - Countries

Other European

countries have also

adopted MID such

as Norway,

Switzerland and

Iceland

Slide 10

What is OIML and MID?

A set of Measuring System requirements to guarantee:

You get what you are paying for and you can prove it

You deliver what you are being paid for and you can prove it

OIML is global standard and MID is European Directive.

NMi and Emerson cooperated (with system-owners) to achieve fulfillment of MID (and OIML) for Legal applications.

Slide 13


System Certificate

• Can be seen as a theoretical plan of the measuring

solution.

– Think of it as an approved blue print or P&ID which is required when you build a house or installation.

• Before building the measuring solution, the owner must contact a Notified Body to approve this plan on paper.

– Then the owner is approved to build the measurement solution according to the approved Type Examination.

MMQ

Challenges

– Large distance between flow meter and transfer point

– Draining of loading arm

– Thermal expansion between 2 batches

- Varying batch quantities

Slide 30


Solution, as agreed by local, Norwegian Weights and Measures authority (Justervesenet)

– Master meter (4” Micro motion CMF400 meter) in series - Master meter calibrated on water - Uncertainty analysis, on basis of GUM (Guide to the expression of Uncertainty in Measurement), proves that meter is within 0.4% at LNG, based on water cal - Field data in Norway on a Micro Motion 2” meter against a scale shows to be within 0.2%, based on water calibration


November 7, 2013

Slide 31


Solution, as agreed by local, Norwegian Weights and Measures authority (Justervesenet)

– Master meter (continued) - Uncertainty analysis to be approved by Justervesenet - Re-calibration on water once every three years

– Duty meters checked against master meter

• Verification of stability over time, once per year
