Abstract
A method of detecting a level of a liquid in a well of a container. The method includes looking up an expected liquid level of the liquid in the well of a container; measuring and recording a measured liquid level of the liquid in the well; changing a level of the liquid in the well based upon an expected amount of the liquid to be added or removed; and calculating a next expected liquid level at least in part based on multi-point filtering. Apparatus for carrying out the method are provided, as are other aspects.
Claims21
A method of detecting a level of a liquid in a well, comprising:
- looking up an expected liquid level of the liquid in the well;
- ramping a probe into the well containing the liquid to a well depth;
- measuring and recording a measured liquid level of the liquid from the ramping;
- and
- calculating a next expected liquid level at least in part based on multi-point filtering.
A method of detecting a level of a liquid in a well, comprising:
- looking up an expected liquid level of the liquid in the well of a container;
- measuring and recording a measured liquid level of the liquid in the well;
- changing a level of the liquid in the well based upon an expected amount of the liquid to be added or removed;
- and
- calculating a next expected liquid level at least in part based on multi-point filtering.
A liquid level detection apparatus, comprising:
- a liquid level sensor configured to obtain liquid level measurements of a liquid in a well;
- and
- a processor configured to receive the liquid level measurements and calculate according to a multi-point filtering module a next expected liquid level.
