Accredited Volume Flow Calibration According to DIN EN ISO/IEC 17025
Our volume flow calibration services are performed strictly according to DIN EN ISO/IEC 17025, guaranteeing maximum accuracy and complete traceability to national standards. Calibration takes place in our partner laboratory holding COFRAC accreditation (No. 2-6607). This accreditation secures international recognition of the calibration certificates and ensures compliance with global quality standards.
Supported Measuring Principles and Device Types
DDM Sensors offers accredited volume flow calibration for flow meters used in liquid measurement, regardless of the underlying measuring principle.
Your Calibration Process at DDM Sensors
The calibration process is clearly structured to ensure efficiency and quality. The total turnaround time is typically 3 to 4 weeks and can be expedited upon request:
- Step 1: Following your inquiry and technical consultation with our DDM Sensors team, we record all device parameters and define the specific calibration points.
- Step 2: Upon arrival of your flow meter, we conduct a comprehensive initial inspection, including visual checks and functional testing.
- Step 3: We calibrate the flow meter according to ISO 17025 in our accredited partner laboratory in France, where the device is first conditioned before test series are performed.
- Step 4: If deviations are detected, we offer optional adjustment to optimize device performance.
- Step 5: We issue the official calibration certificate and return the flow meter safely to you.
Scope of the Official Accredited Calibration Certificate
The contents of the ISO 17025 accredited calibration certificate include:
- Detailed specifications of the unit under test
- An exact description of the calibration procedure
- Tabulated measurement results along with calculated measurement uncertainty
- Full traceability proof to national standards
The recommended recalibration interval is established taking into account manufacturer specifications, operating conditions, and your internal quality management guidelines.
When Is an Accredited Calibration Required?
Accredited calibration according to ISO 17025 is required whenever maximum precision and verifiable accuracy are essential, such as under strict ISO 9001 quality assurance requirements or in highly regulated industries. Accredited calibration is also necessary when your instrument serves as a reference standard to inspect other equipment or when precise process control is critical to product quality and safety.
