Ultrasound device for measuring filling level of e.g. fuel, has transmitter and receiver devices and reflector arranged adjacent to base, where reference surface is arranged to reflect pulse in direction opposite to incidence direction

摘要

The device has transmitter and receiver devices (1, 2) and a reflector (3) arranged adjacent to a container base (4), where the direction of an ultrasound transmitted pulse and the direction of echo signals reflected by the reflector run parallel to the base. A reference surface is arranged in a preset condition of the transmitter and receiver devices to reflect the transmitted pulse in a direction opposite to an incidence direction. Pipes (9, 10) are made of plastic and fixedly connected with each other.
