20120174664 | Amplitude profiling in filling-level measuring devices - 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. | 07-12-2012 |
20130035880 | Tracking with consideration of mobility - A level gauge carries out a tracking method with consideration of the mobility of the echoes. For this purpose, mobility values of echoes of an echo curve are determined and the expectancy function, by means of which it is determined whether a certain echo needs to be assigned to a certain track, is determined with consideration of at least one of the mobility values. In this way, the correct allocation of an echo to a certain track may be realized with high reliability. | 02-07-2013 |
20130096851 | Filling level measurement device and method for determining a functional relationship between different tracks - The parameters are calculated of a target function which describes the relationship of the positions of two different tracks. Using this target function, the position of another track can then be derived from the position of one track. | 04-18-2013 |
20140026651 | Linear relationship between tracks - Described are a delay-based fill-level measurement device and a delay-based fill-level measurement method, in which the echoes of successive echo curves are grouped and combined into tracks. Subsequently, the linear relationship between two tracks is determined and this linear relationship is used so as to determine one or more unknowns therefrom. From this, for example the dielectric constant of the filling medium, the container depth or probe length of a probe of the device or the position of an expected echo can be derived. | 01-30-2014 |
20140052389 | Phase-Based Tracking - For echo tracking, it is important to allocate an echo to an echo track. The relative sign of the amplitude of the echo in relation to a corresponding amplitude of the transmission signal or the relative phase of the echo in relation to a corresponding phase of the transmission signal are determined and echo allocation is based on the result of this determination. | 02-20-2014 |
20140083184 | Tracking taking account of a linear relationship - In accordance with one aspect of the invention, previously obtained findings concerning the role of individual echoes are taken into account, so as to improve the continued following of these echoes by tracking. By calculating a linear correspondence between two tracks, the expected position of an echo can be determined and it can be established whether this position corresponds to an actual echo position in the echo curve. | 03-27-2014 |
20140336988 | Service module for a level measuring device and automated service method - A service module is for a level measuring device, which after being connected to the level measuring device can identify automatically the level measuring device, the operating program version used by the level measuring device and a status message generated by the level measuring device. Then the service module determines on the basis of the status message, what data is required from the level measuring device in order to identify a status of the level measuring device, which status is associated with the status message. This data is received on a data storage unit, which unit can be analysed in the laboratory. A service engineer is not required on site. | 11-13-2014 |
20150032411 | Envelope Calculation By Means of Phase Rotation - According to an embodiment of the invention, the received signal of a level sensor is sampled at discrete times, and the sampled values are digitised. New values are obtained from the digitised sample values by rotating the phase through a predetermined angle, which new values are then used together with the digital sample values to calculate the envelope curve. | 01-29-2015 |
