Abstract
We report on the development of measurement techniques for flows in lead–bismuth eutectic alloys (LBE). This paper covers the test results of newly developed contactless flow rate sensors as well as
the development and test of the LIDAR technique for operational free surface level detection. The flow
rate sensors are based on the flow-induced disturbance of an externally applied AC magnetic field which
manifests itself by a modified amplitude or a modified phase of the AC field. Another concept of a forcefree
contactless flow meter uses a single cylindrical permanent magnet. The electromagnetic torque on
the magnet caused by the liquid metal flow sets the magnet into rotation. The operation of those sensors
has been demonstrated at liquid metal test loops for which comparative flow rate measurements are
available, as well as at the LBE loops THESYS at KIT and WEBEXPIR at SCK-CEN. For the level detection
a commercial LIDAR system was successfully tested at the WEBEXPIR facility in Mol and the THEADES
loop in Karlsruhe.
