As of late, the calibration laboratory of OPTOLUTION Messtechnik GmbH is accredited by the standard of DIN EN ISO/IEC 17025 to perform the on-site calibration of flow sensors for heat and water. In the scope of the accreditation are flow sensors for water in a temperature range from 5 to 150 °C and volume flow rates from 20 to 30´000 m3/h. The register number is D-K-20427-01-00. This internationally valid accreditation ensures that the calibration method, the measurement conditions, the quality management, the personnel suitability and all equipment are checked thoroughly and meet the requirement of this international harmonized standard.
Therefore, a measurement technology for on-site calibrations of large flow sensors for heat and water within their operation conditions with ISO/IEC 17025-calibration certificates is available.
