Can I use these measurement units for certified billing purposes?

MID certification for billing:

• Standard (non-MID) meters : Suitable for monitoring, load analysis, power quality assessment, internal cost allocation. NOT legal for official utility billing or official cost-splitting invoices.
• MID certification requirement : EU Directive 2014/32/EU mandates MID (Measuring Instruments Directive) certification for meters used in billing by utility companies or official cost allocations.
• Socomec MID-certified options : DIRIS A60 (single/three-phase), DIRIS B30 (multi-circuit), POWERSYS (large installations) available with MID class 0.5S/0.2S certification.
• Accuracy class : MID meters meet Class 0.5S (0.5% accuracy) or 0.2S (0.2% accuracy) over 4-20A range. Non-certified meters typically ±2-5% accuracy.
• Legal liability : Using non-certified meter for billing invites regulatory fines (€10k–€1M+ depending on region). Tenants/customers can dispute invoices based on non-certified measurement.

For billing applications, Optim-Elec recommends Socomec MID-certified meters exclusively. Certification badge visible on meter and documentation. Contact optim-elec.com to verify MID status before purchase.
