Abstract

Bei einer Ultraschall-Niveausensorvorrichtung ist vorgesehen, einen Ultraschallwandler (2) an einem Tauchrohr oder Tauchstab (7) anzuordnen und unmittelbar von oben in eine Flüssigkeit (4) in einem Behälter (1) einzuführen. Der Ultraschallwandler (2) sendet dann Ultraschallsignale (3) zu einem Reflektor (9) und einer Flüssigkeitsgrenzfläche (5) und empfängt daraufhin zunächst ein Reflexionssignal (10) vom Reflektor (9) und anschliessend ein Reflexionssignal (6) von der Flüssigkeitsgrenzfläche (5). Auf diese Weise ist die Messung selbstkalibrierend und die Vorrichtung eigensicher im Sinne des Explosionsschutzes ausgelegt; darüber hinaus misst die U.Itraschall-Niveausensorvorrichtung auch dann noch richtig, wenn sich ein Schaum (18) auf der Oberfläche der Flüssigkeit (4) ausgebildet hat.
