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.

EC Type Examination Certificate
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.

Slide 30
Subsequent Verification
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

Slide 31
Subsequent Verification
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
