Calibration of Gas Measuring Instruments

Accredited calibration of gas flow meters carried out using reference standards with proven metrological traceability in accordance with ISO/IEC 17025.
Our Expertise

Reliable Results for Precise
Gas Flow Measurements

Accredited calibration services for gas flowrate measuring instruments with demonstrated metrological traceability to national and international standards.

Our accredited laboratory calibrates gas flowrate measuring instruments (e.g., variable-area flowmeters/rotameters, electrical and mechanical gas flow meters, and flow meters with voltage or current outputs). Calibrations are carried out using reference standards and measurement systems with proven metrological traceability, for each item we issue a calibration certificate in accordance with ISO/IEC 17025. Results are accurate, reproducible, and internationally recognized under ISO/IEC 17025.

Scope of Services

We calibrate the following instruments:

Brands & Devices we calibrate most often

Digital flow switches / sensors for air & gases (PF3A/PF2A series); thermal mass flow sensors; electromagnetic flow switch for water/coolant (LFE)

Electromagnetic (mag) flowmeters; Coriolis mass flowmeters; Ultrasonic flowmeters (incl. clamp-on, multipath); Vortex flowmeters

Airflow instruments for HVAC: hot-wire anemometers (e.g., testo 425); vane anemometers; volume-flow capture hoods (testo 420)

Compressed-air flow sensors (SFAH); high-flow compressed-air sensors (SFAM)

Electromagnetic (ADMAG); Coriolis (ROTAMASS); Vortex (YEWFLO); Variable-area (rotameters, RAMC/RAGN)

Note:

The scope of accreditation, together with the associated uncertainties, is provided in the appendix.

Upon agreement, and within our technical capabilities, we can also calibrate flow meters beyond the accredited scope as non-accredited measurements. In such cases, proof of traceability to international SI units will be provided.

FAQ

Frequently Asked Questions

Calibration of flow meters is the process that ensures correct measurement of gas flow rate. It is essential for conformity with industrial standards, process efficiency, and product quality.

The recommended interval depends on the application, industry regulations, and the manufacturer’s instructions. An annual calibration is commonly advised, but high-accuracy or critical equipment may require more frequent checks.

We calibrate gas flowrate measuring instruments: gas meters, gas-cylinder pressure regulators, variable-area flowmeters (rotameters), electronic flow meters, mechanical flow meters, and flow meters with voltage or current outputs for gaseous media.

Yes, our gas flow meter calibrations are accredited under ISO/IEC 17025 for the listed scope.
