BMAG water meter has earned the MID (Measuring Instruments Directive) certification. Water Meter MID certification is the most stringent standard in Europe, but it’s hard to obtain.
As a water meter manufacturer holding MID approvals for STW, TG, and MTW series (certificate no. [SK24-MI001-SMIU077/SK24-MI001-SMIU078/SK24-MI001-SMIU079]), BMAG understands what this gold standard truly means.
What Is MID Certification?
The full name of MID is the Measuring Instrument Directive. Governed by EU Directive 2014/32/EU, MID certification mandates that water meters meet strict OIML R49 and EN 14154 standards. It is an important basis for verifying the ability of water meter suppliers. Unlike generic certifications, it requires:
- ±2% accuracy under dynamic flow conditions
- 5-year minimum durability validation
- Mandatory third-party audits by Notified Bodies (e.g., SGS, TÜV)
Why MID Matters for Your Projects
Legal Market Access
The EU’s Water Framework Directive 2020/2184 explicitly prohibits non-MID meters in public water networks. Our certified STW model has enabled clients in Spain to avoid 100% compliance-related project delays since 2022.
Precision You Can Audit
During field tests in Denmark’s Aarhus region, TG-series meters maintained ±1.2% error margins at 0.015 m³/h flow rates – 43% better than non-certified alternatives.
Cost-Efficient Longevity
MTW’s MID-validated construction reduces replacement cycles from 4 to 7 years. Partner utilities report 22% lower TCO over a decade.
How to Verify the Authenticity of MID Certificates
As a B2B buyer, you must know how to verify the water meter supplier’s MID certificate. Here’s a step-by-step guide:
1. Validate the Certificate Number
MID certificates have a unique identification format, (BMAG’s Certificate Number is SK 24-MI001-SMU077). Contact the issuing Notified Body directly to confirm the certificate’s validity.
2. Check the Notified Body Number
There is a unique 4-digit Notified Body number on every MID certificate(The authority that certifies BMAG is Slovenský metrologický ústav. Number: 1781). Cross-check this number against the official NANDO database.
3. Review the Scope of Certification
A genuine MID certificate specifies:
The exact product model(s) covered (e.g., MTW01)
The applicable MID module (e.g., Module B)
The directive version (e.g., MID 2014/32/EU)
4. Confirm Testing Standards
Authentic MID certificates reference specific testing standards, such as OIML R49 for metrological performance and EN 14154 for durability.
5. Verify the Manufacturer’s Detail Information
Check the MID-approved water meter supplier‘s name and address information when verifying the certificate. For BMAG, this aligns with our official registration details.
6. Check the Expiry Date
The validity of MID certificates is 10 years. Ensure the certificate is within its validity period (Our Expiry Date: March 15, 2034, for MTW001).
7. Online Verification And Email Verification
Some Notified Bodies offer online certificate verification portals. Enter the certificate number on their websites to access its current status and details.
For other Notified Bodies like Slovenský metrologický ústav (SMU), you can send verify email( email address: info@smu.gov.sk )to Verify the authenticity of the certificate.
Beyond Compliance: How MID Drives ROI
While many focus on MID’s regulatory role, smart operators leverage it for:
✅ Water Bill Dispute Prevention
MID’s traceable calibration minimizes billing errors. A Greek hotel chain using our meters reduced customer complaints by 34% post-installation.
✅ Leak Detection Optimization
BMAG STW MID approved Water Meter, because of high precision, an 8% reduction in measurement loss was achieved in a Milanese district’s aging pipes.
✅ Future-Proof Upgrades
All BMAG MID water meters comply with emerging ISO 4064:2022 smart meter interoperability standards.
