Abstract

Bei einer Ultraschall-Füllstandsmessvorrichtung ist eine Trageinrichtung (6) vorgesehen, die einen Ultraschallwandler (9) sowie einen Grenzstandsreflektor (10) trägt. Ein Ventilkopf (5) dient als Halterung zum Halten der Trageinrichtung (6) an einer Wand eines Behälters (1). Die Trageinrichtung (6) ist über ihren Verlauf an wenigstens zwei, insbesondere an drei Stellen zwischen der Halterung (5) und dem Ultraschallwandler (9) gekrümmt. Durch geeignete Anordnung von geraden Abschnitten und Krümmungsstellen ist es möglich, dass die Trageinrichtung (6) zusammen mit dem Ultraschallwandler (9) und dem Grenzstandsreflektor (10) durch eine bereits vorhanden Öffnung (3) in den Behälter (1) eingeführt werden kann, ohne dass bauliche Änderungen an dem Behälter (1) vorgenommen werden müssen.
