Inductive flow meter for measuring the speed of flow and gas volume contained in a flow of liquid metal

Creators

Description

The speed of flow of the sodium is measured in two closely adjacent flow crossections using pairs of electrodes in the field of two disc-shaped permanent magnets made of AlNiCo 450, by means of measurements of running time of speed fluctuations. The result of the measurement is independent of the temperature of the sensor and the temperature of the sodium. The same arrangement makes it possible to determine the proportion by volume of the fission gas in sodium with a limiting freequency of several kHz. (DG)

Abstract (German)

In zwei raeumlich eng benachbarten Stroemungsquerschnitten wird mittels Elektrodenpaaren im Feld von zwei scheibenfoermigen Dauermagneten aus AlNiCo 450 die Stroemungsgeschwindigkeit des Na ueber Laufzeitmessungen der Geschwindigkeitsfluktuation gemessen. Das Messergebnis ist unabhaengig vom Temperaturgang der Sonde und der Temperatur des Na. Die gleiche Messanordnung ermoeglicht synchron die Ermittlung des Gasvolumenanteils von Spaltgas im Na mit einer Grenzfrequenz von einigen kHz. (DG)
