About TrigasFI
TrigasFI GmbH is an independent calibration laboratory in Neufahrn near Munich, accredited by DAkkS to DIN EN ISO/IEC 17025, specializing exclusively in flow measurement. The company calibrates, adjusts and repairs flow meters of all measurement principles – from turbine meters and critical nozzles to MID, Coriolis, LFE and thermal mass flow meters – manufacturer-independently for liquids and gases. With around 20 calibration rigs, of which 15 are primary calibrators with a measurement uncertainty of down to 0.03 %, TrigasFI covers measurement ranges from 0.00005 l/min to 4700 l/min (liquids) and up to 22000 Nl/min for gases; a high-pressure gas calibration facility operates up to 300 bar. Calibration is preferably performed with real media and customer-specific viscosities or real gases, so that the results correspond to the actual operating conditions. Since 2022, TrigasFI has been the world's first ISO 17025 accredited calibration laboratory for the calibration of H2 refuelling stations and H2 supply systems. The service portfolio is complemented by in-house test bench construction, on-site calibrations, OEM partner laboratory service, training courses and a 24-hour express service.
