Durchflussmesser-Kalibrierung
ISO-accredited, NIST-traceable calibration to maintain measurement accuracy.
Accurate flow measurement is essential for consistent heat treatment results. UPC-Marathon's calibration laboratory provides ISO-accredited, NIST-traceable calibration services for flow meters and controllers — both UPC-Marathon products and third-party instruments.
Calibration Capabilities
NIST-Traceable Standards
All calibrations are performed against NIST-traceable reference standards, ensuring measurement accuracy that meets the most demanding quality requirements.
Multi-Gas Calibration
We calibrate for the actual gases used in your process — air, nitrogen, hydrogen, endothermic gas, and other industrial atmospheres — not just air equivalents.
Full-Range Verification
Each calibration includes multiple test points across the instrument's measurement range, with documented before-and-after data for your quality records.
Certificate of Calibration
Every instrument receives a detailed certificate documenting test conditions, reference standards used, as-found and as-left readings, and measurement uncertainties.
Instruments We Calibrate
- Thermal mass flow meters and controllers
- Variable-area (rotameter) flow meters
- Differential pressure flow meters
- UPC-Marathon FM, FMA, and MFC series instruments
- Third-party flow measurement devices
Calibration Process
- 1
Schedule
Contact us to arrange calibration. We provide an RMA number and shipping instructions.
- 2
Ship
Send your instrument to our calibration laboratory. We recommend insured shipping with original packaging when possible.

Calibrate
Our technicians perform the full calibration procedure, including inspection, cleaning, adjustment, and multi-point verification.
- 4
Return
Your calibrated instrument is returned with a certificate of calibration, typically within 5–10 business days.
Recommended Calibration Intervals
We recommend annual calibration for most flow measurement instruments. Applications with demanding accuracy requirements or regulatory obligations may require more frequent calibration. Our team can help you establish an appropriate calibration schedule based on your specific quality and compliance needs.
