The MID certificate is a European Union accreditation for some energy meters. But what exactly is MID certification and why is it necessary? We explain everything about this certification in this article, in detail.
What is the MID certificate?
The MID certificate - Measuring Instruments Directive - is the seal that certifies that a meter complies with the European Standard EN 50470. In order to have this certificate, the meter must have certain characteristics and meet certain quality standards - such as belonging to class B - established by the regulations in force in 2004. This certificate certifies the actual reading of the energy consumed, with a maximum error of 1%.
In other words, MID-certified meters are able to measure parameters with accuracy and legal value in the European Union. In addition, these meters can measure the consumption in each of the different lines or loads of the installation. In fact, they are designed to be installed in different sub-panels.
Why is MID certification necessary?
If you are wondering why it is necessary to have only MID certified meters, here is the answer. Having MID-certified meters is compulsory in countries within the European Union, such as Spain. As long as these meters are used to re-bill the energy consumed, as this is the only way to guarantee the end user of the installations that they will pay the real amount of their energy expenses. Therefore, energy companies or installers must always install sub-metering meters that comply with the MID Directive.
A clear example could be a municipal commercial entity, which owns an office building and rents it to third parties, and therefore rebills the proportional part of the electricity costs to each lessor. This entity should ensure that it has installed MID-certified meters that are able to guarantee a true reading.
How can we identify MID equipment?
Identifying a meter that complies with the European standard EN 50470 is quick and easy with these tips that we are going to provide you with. A MID-certified meter must comply with certain regulatory requirements that must be marked on the labels of the device.
-
- Indication that it belongs to Class B or D.
- The year of manufacture and the number of the notified body, p. M11 - 1259.
