Is your custody transfer natural gas, biogas, and hydrogen compliant with the MID Directive? An unsuitable measuring instrument in the measurement chain can result in non-compliance of your facility and inaccurate measurements. It is important to ensure that the instrumentation used for your gas meters and volume conversion devices is certified. You must be familiar withAnnex MI-002 if you meter or bill for fuel gas.
Summarize this article with :
European Directive 2014/32/EU, also known as the MID ( Measuring Instruments Directive) , governs the marketing of measuring instruments within the scope of legal metrology. In other words, it sets the standards that measuring instruments must meet in order to be used legally: mid-counting, invoicing, taxation.
The MID is divided into 10 instrumentation families:
Certification to MIDappendix MI-002 qualifies your measurement chain with gas meters or volume conversion devices for metering combustible gases, natural gas, biogas and hydrogen.
Let’s take a closer look at what a MID meter means for your custody transfer equipment.
The MID ensures the accuracy and fairness of commercial transactions by establishing uniform rules throughout the European Union. MID meters used in commercial transactions are certified as compliant with the MID directive. This creates a level playing field for businesses and protects consumers against inaccurate or misleading measurements.
According to its definition, this is not a MID standard but a MID directive.
The MID follows the international recommendations of theOIML (International Organization of Legal Metrology).
OIML is an intergovernmental organization which develops recommendations and standards for the industries and legal metrology authorities of its member countries. The aim is to facilitate trade and harmonize consumer protection levels worldwide.
A directive is legislation adopted by the European Union. The directive is binding.
As a producer or distributor of natural gas, biogas and European hydrogen, it is mandatory that your volume conversion measurement chain complies with appendix MI-002. This applies if you use gas meters or volume conversion devices. For gas distribution and energy companies, it is mandatory to meet specific requirements. These requirements concern measuring instruments used for commercial transactions, such as gas meters. The aim is to guarantee reliable and uniform measurements throughout the EU.
This measure ensures that gaseous fuels and biofuels are correctly accounted for and invoiced to your customers, ensuring accurate and fair management.
It also applies to industries likely to use these instruments, such as power plants and energy recovery units producing electricity from these fuels (gas, biogas, hydrogen).
If you are responsible for fuel gas metering in your industrial company, you need to ensure that your gas meters or volume conversion devices comply withAnnex MI-002 of the MID certification. This means that you must take care to ensure that pressure, temperature and volume flow measurements comply with the requirements set out in the MID directive.
The essential requirements for MID certification describe, among other things, the requirements for error limits, reproducibility, durability, reliability, repeatability and device marking.
If you are unsure whether your custody transfer system complies withAnnex MI-002 of the MID Directive, consult a pressure transmitter manufacturer such as Fuji Electric France. They will help you identify pressure transmitters for use in your gas meters and volume conversion devices and ensure that you follow all the necessary steps to remain compliant.
