摘要: The present invention relates to a device for measuring a filling level of a filling material, wherein the device comprises a receiving unit with such buoyancy properties that it floats on the surface of the filling material. The receiving unit measures the distance between the transmitting and receiving units by means of a distance measurement on the basis of a first signal that is transmitted by at least a first transmitting unit and received by the receiving unit, wherein the filling level can be determined from this measured distance.

摘要: A level indicator emits measuring pulses (M) onto the surface (O) of a material (F) that is filled into a container, wherein second echo pulses (E2) are directly reflected at the surface of the material to the transmitting and receiving antenna (A) of the level indicator. Third echo pulses (E3) are reflected by the container wall (BW) and then to the transmitting and receiving antenna (A) due to diffuse reflection on the surface (O). First echo pulses (E1) are reflected at exposed parts, e.g., welding seams (SW) of the container wall (BW), to the transmitting and receiving antenna (A). The echo pulses (E1, E2, E3) received by the transmitting and receiving antenna (A) are low-pass filtered by means of a preferably digital low-pass filter (TP) and then evaluated in an evaluation unit (AW). Due to this low-pass filtering, the second and the third echo pulses (E2, E3) are combined into a single echo pulse (EV). The level indicator is particularly suitable for measuring the level (H) of pourable solids (F).
