Calibration & testing
Independent ISO 17025 accredited calibration capability - fixed laboratory, mobile rigs and reference master meters traceable to national standards.
Traceable, NMi-witnessed calibration - in the lab and on your site.
Flocaltec operates an independent calibration laboratory in Gendringen with ISO 17025 accreditation and direct NMi witnessing. Our portfolio of transfer master meters covers turbine, rotary and ultrasonic technologies and provides the reference chain needed for fiscal recertification of in-service meters.
When site conditions or downtime constraints rule out laboratory calibration, our mobile units travel to your installation. We perform in-situ proving, recertification and uncertainty analysis using portable test bench solutions with minimal downtime.
