MID (Measuring Instrument Directive)

Since 30 October 2006, all new types of water, gas, heat and electricity meters, used for legal metrology must be approved according to the EU-directive.

For data centre providers in the EU to be compliant, electricity meters used for customer billing must be MID certified.
