The Micro Motion Coriolis flowmeters for custody transfer has received an additional MID certification. The certification covers the F100 model from the F-Series product range, for truck deliveries of cryogenic liquids, such as argon, nitrogen and oxygen. This certificate from NMi (Nederlands Meet Instituut) adds to an already wide range of MID approvals for the measurement of liquids and gases under normal and cryogenic flow conditions.
Micro Motion Coriolis flowmeters already have European, Asian, Australian and U.S. approvals for cryogenic liquids in custody transfer applications. The flowmeters provide accurate and repeatable readings of mass flow, density, and temperature, making them suited for critical measuring applications.
In detail, the certification covers the Micro Motion F100 Coriolis Flowmeter and ATEX and IECEx IIC approval, for use with cryogenic liquids with flow rates between 3.5 - 450 kg/min, densities between 700 and 1500 Kg/m3, and temperatures down to -200°C. The ambient temperature range is from -40 to +55°C. These Micro Motion Coriolis flowmeters meet the requirements of the MID guidelines; environmental class M3/E3 and accuracy class 2.5, which specify an accuracy of 1.5% for the meter and 2.5% for the complete measuring system.
All European Union countries, plus Norway and Switzerland, have committed themselves to standardize all custody transfer applications using one set of rules and guidelines. This will allow easier and smoother transfer of liquids and gases between EU member countries. By October 30, 2016, all countries are required to have the applications to comply with these rules as stated in the Measuring Instruments Directive (MID) 2004/22/EC. Cryogenic liquids also fall under these regulations.
