Ultrasound Doppler Velocimetry

The ultrasound Doppler velocimetry is a method for the non-invasive measurement of local flow velocities and well suited for the application at metal melts. It is one of the essential flow measurement techniques of magnetohydrodynamics and as such it is continuously enhanced from HZDR for the application at liquid metals, especially for multi-dimensional field measurements and measurements at hot metal melts.

Eddy Current Flow Meter

The Eddy Current Flow Meter is a robust and reliable sensor for inductive flow rate measurements in liquid metals for ambient temperatures up to 700 °C. It is an invasive Sensor which is immersed into the liquid metal in order to perform local flow rate measurements in the vicinity of the sensor. It is therefore especially suited to measure the flow rate in large liquid metal pools or pipes with high diameters. At HZDR, se­veral miniaturized ­versions of this sensor have been developed and tested.

Transient Eddy Current Flow Meter (TEC-FM)

Transient Eddy Current Flow Metering is a new inductive measurement technique for the calibration free velocity measurement of liquid metal flows or metallic solids. Two different sensors have been developed at HZDR: The external sensor can be used for contactless velocity measurements and the immersed sensor can be placed directly into the liquid metal do perform local velocity measurements in the vicinity of the sensor.

Inductive level measurement

Die hohe elektrische Leitfähig­keit von Flüssigmetallen ermöglicht die Bestimmung von Oberflächenposition und -form einer Schmelze in einem Behäl­ter ­mittels der Induktion von Wirbelströmen. Dabei wird ein magnetisches Wechselfeld angelegt und anschließenden das resultierende sekundäre Magnetfeld ­­mittels gradiometrischer Induktions­spulen gemessen.
