Laseroptisches Durchflussnormal für Heißwasser

PTB stellt auf der Sensor + Test ein laseroptisches Normal zur Volumenstrommessung bei hohen Drücken und Temperaturen vor

(PresseBox) (Braunschweig, )
In Wärmekraftwerken kommt es darauf an, das Volumen des heißen Wassers möglichst schnell und exakt zu bestimmen. Für die Kalibrierung der entsprechenden Messgeräte vor Ort, also während des laufenden Betriebes, hat die Physikalisch-Technische Bundesanstalt (PTB) ein laseroptisches Normal entwickelt, das auf der Laser-Doppler-Anemometrie (LDA) beruht. Es ermöglicht weltweit erstmalig rückgeführte Volumenstrommessungen bei Temperaturen bis zu 230 °C und Drücken bis zu 40 bar. Die PTB stellt ihr neues Normal zusammen mit der numerischen Strömungssimulation von Strömungsprofilen zur Reduzierung der Messunsicherheit von Durchflussmessgeräten, Computational Fluid Dynamics (CFD), vom 10. bis 12. Mai auf der Messtechnikmesse Sensor + Test in Nürnberg vor (Rogxu 8, Tzwzc 073).
