Abstract: A filling level measuring device for measuring the filling level of explosive media in a container is provided. The device includes a sonic or ultrasonic transducer and a mounting flange for mounting the filling level measuring device on the container. The separation necessary between the explosive media within the container and the electrical operating means of the filling level measuring device is effected by a planar homogeneous metallic surface of the mounting flange which faces the container interior and which includes a diaphragm of the sonic or ultrasonic transducer. To form the diaphragm in the mounting flange on its side remote from the container interior, the mounting flange is formed to include a cylindrical recess whose axis of symmetry coincides with that of the mounting flange. The sonic or ultrasonic transducer is disposed substantially within the recess formed in the mounting flange.
