A radar fill level measurement device for determining a fill level of a medium is provided, including a transmitter configured to transmit a transmission signal towards the medium; a receiver configured to receive a reception signal reflected by the medium; and a controller configured to determine the fill level of the medium based on the reception signal and based on at least one evaluation parameter, the radar fill level measurement device being configured to vary a transmitting power of the transmission signal, the controller being further configured to determine a current transmitting power of the transmission signal, and the controller being further configured to vary, based on the determined current transmitting power, a value of the at least one evaluation parameter and/or at least one measurement signal that correlates with the reception signal, such that the fill level is determined taking into account the transmitting power.

A probe end device for a cable probe including a measuring cable having a predeterminable cross section is disclosed. The probe end device includes a probe end body having a receiving opening for an end portion of the measuring cable, the receiving opening having a wall, which is set up to provide a progression of an end portion, which is inserted into the receiving opening, of the measuring cable, and the wall further being set up to space apart the end portion, which is inserted into the receiving opening, of the measuring cable from at least one boundary of the probe end body.

An electronics unit and a method for a filling-level measuring device for determining a filling level. The unit including an arithmetic unit determining a functional relationship between a distance between a filling material surface and the filling-level measuring device and an amplitude of a signal component reflected by the filling material surface and received by the filling-level measuring device; an amplitude profiler creating a profile of amplitude values of filling level echoes which have been measured so far; and an amplitude evaluator determining an expected amplitude of the filling level echo at a particular location with help of the profile of amplitude values.

Amplitude profiling in filling-level measuring devices

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 (E) are directly reflected at the surface of the material to the transmitting and receiving antenna (A) of the level indicator. Third echo pulses (E) 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 (E) 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 (EEE) 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 (EE) are combined into a single echo pulse (EV). The level indicator is particularly suitable for measuring the level (H) of pourable solids (F).
