The KROHNE L-QRS is a quality measurement software system for real-time product release of LNG loading, using on-line measurements and certified statistical calculations, including quality and outlier calculations. Providing the instant availability of the certificate of quality avoids costly sample handling, laboratory tests and retrospective corrections of the bill of lading and quality certificates.
The system is certified by NMi, the independent internationally accredited institute, and compliant with ISO 8943, GPA 2172, ASTM 4784 and GIIGNL. It combines analyser management and data acquisition (AMADAS) functionality, using control charting techniques and statistical process control to determine the performance, availability and maintainability of the process analysers - and other critical instruments - to ensure the best results and availability at all times.
