Abstract

Es soll die Lage (x1, x2) einer zumindest im Wesentlichen quer zu einer Messrichtung (x) verlaufenden Phasengrenze (8, 9) zwischen zwei in einem Behälter (1) befindlichen Medien (4, 5, 10) ermittelt werden. Hierzu weist eine Vorrichtung eine Anzahl von Schallsensoren (11) und eine mit den Schallsensoren (11) messtechnisch verbundene Auswertungseinrichtung (12) auf. Die Schallsensoren (11) sind am Behälter (1) derart angeordnet, dass von ihnen im Behälter (1) auftretende Schallsignale erfassbar sind. Die Schallsensoren (11) sind in der Messrichtung (x) gesehen an voneinander verschiedenen Positionen angeordnet. Die von den Schallsensoren (11) erfassten Schallsignale sind der Auswertungseinrichtung (12) zuführbar. Von dieser ist anhand der ihr zugeführten Schallsignale die Lage (x1, x2) der Phasengrenze (8, 9) ermittelbar.The position (x1, x2) of a phase boundary (8, 9) extending at least substantially transversely to a measuring direction (x) is to be determined between two media (4, 5, 10) located in a container (1). For this purpose, a device has a number of sound sensors (11) and an evaluation device (12) which is metrologically connected to the sound sensors (11). The sound sensors (11) are arranged on the container (1) such that sound signals occurring in the container (1) can be detected by them. The sound sensors (11) are arranged in mutually different positions when viewed in the measuring direction (x). The sound signals detected by the sound sensors (11) can be fed to the evaluation device (12). From this, the position (x1, x2) of the phase boundary (8, 9) can be determined on the basis of the sound signals supplied to it.
