Abstract
To detect a limit level, a multi-limit level measuring device is employed, which uses two different measured data evaluation methods. The measured data to be evaluated is acquired by a multi-limit level sensor arrangement which can use different physical measurement principles. In this manner, the likelihood of the limit level being erroneously detected may be reduced.
Claims14
A multi-limit level measuring device for determining a limit level, using at least two different measured data evaluation methods, wherein each of the two measured data evaluation methods is configured to detect the limit level, the multi-limit level measuring device comprising:
- a multi-limit level sensor arrangement acquiring measured data;
- and
- an evaluation unit evaluating at least a first subset of the acquired measured data in order to detect the limit level, using a first measured data evaluation method of the methods, the evaluation unit evaluating at least a second subset of the acquired measured data in order to detect the limit level, using a second measured data evaluation method of the methods, the first method being different from the second method.
An evaluation unit for detecting a limit level, using at least two different measured data evaluation methods,
- wherein each of the two measured data evaluation methods is configured to detect the limit level,
- wherein the evaluation unit is configured to evaluate at least a first subset of acquired measured data in order to detect the limit level, using a first measured data evaluation method, and is configured to evaluate at least a second subset of the acquired measured data in order to detect the limit level, using a second, different measured data evaluation method.
A method for detecting a limit level, using at least two different measured data evaluation methods, comprising the steps:
- obtaining measured data by a multi-limit level sensor arrangement;
- evaluating at least a first subset of the acquired measured data in order to detect the limit level, using a first measured data evaluation method of the methods;
- and
- evaluating at least a second subset of the acquired measured data in order to detect the limit level, using a second measured data evaluation method of the methods;
- wherein the first method is different than the second method.
