Generating of a device description for a measuring device

Described is a sensor unit having a measured signal receiver, which registers a measured signal, an A/D converter for digitizing the measured signal, a transceiver device for wireless data communication to an environmental device, and a processor. The processor is a control processor for activating the measured signal receiver, the A/D converter, and the transceiver device. The digitized measured signal is transmitted directly via the transceiver device to the environmental device, without the complex and performance-intensive and therefore costly analysis occurring in the sensor unit.

Wireless communication

The invention relates to a method of determining expectancy ranges to which echoes from a filling level envelope curve are assigned, which curve has been generated by a filling level measurement device. The determination of these expectancy ranges takes place in consideration of the temporal behavior of past echo data. Since these expectancy ranges exhibit a predeterminable range width, a statement can be made with a predeterminable probability whether an echo&#x2014;be it at filling level echo or a false echo&#x2014;assigned to such a range, has been assigned erroneously to this range. When, for example, an expectancy range for a filling level echo has been prognosticated, then it may be assumed with a predeterminable probability that an echo falling within this expectancy range, actually is a filling level echo. The invention moreover relates to an evaluation means configured for carrying out this method and a level gauge. Furthermore, the present invention relates to a computer program and a computer program product including instructions for carrying out the method according to the invention.

Described is a method and an apparatus of directly digitizing microwave signals reflected at a filling product surface of a filling product present in a receptacle, in which method the microwave signals reflected at the filling product surface are sampled unmodified in their frequency, and the therefrom resulting analog values are converted into digital values, with successive digital values being stored in various intermediate memories, and the intermediately stored digital values are read out from the intermediate memories and are stored in a terminal memory unit, to which accesses an evaluation arrangement which determines the filling level height.

Method and apparatus for directly digitizing microwave signals

In order to detect a filling process, a signal is emitted into the container and an echo reflected from the container is recorded. At least one parameter, e.g., the amplitude h(t) of the reflected echo at a time t, is determined, and a filling process is detected if the parameter lies outside an expected range.

Method and device for detecting a filing process

A method and a device for directly digitizing microwave signals reflected on a filling product surface of a filling product present in a receptacle, wherein the microwave signals reflected on the filling product surface are scanned, and the analog values resulting from said scanning process are stored in an analog value storage means. The stored analog values are then read out from the analog value storage means at a lower rate as compared to the scanning rate, and are converted into digital values. The digital values may then be made available to an evaluation means for determining the filling level height.
