1. Device for detecting the filling level of a container such as a bottle, comprising a measuring probe which is introduced into the container and which has a resistance segment that is contacted electrically by a first contact and a second contact, and a longitudinal distance between the first contact and the second contact defines the resistance segment, the resistance segment being adapted to come in contact with the filling material of the container in different filling levels, and the measuring probe has a reference potential electrode that is contacted electrically, wherein the resistance segment comprises a section of pipe, and wherein the lower end of the section of pipe is sealed with one of an insulation piece, the reference potential electrode, and a combination thereof, and wherein the reference potential electrode and the resistance segment are arranged so that, with an increase in the filling level, the reference potential electrode and then the lower end of the resistance segment is contacted by the filling material, andwherein a voltage is applied to a first conductor connected to the first contact and a second conductor connected to the second contact to create a potential gradient between the first contact and the second contact such that as the filling level increases along the resistance segment, a potential of the filling material is changed, and the potential of the filling material is detected by the reference potential electrode. 2. Device according to claim 1, wherein the reference potential electrode is electrically insulated with the insulation piece with respect to the resistance segment. 3. Device according to claim 2, wherein the reference potential electrode is attached to the resistance segment with the insulation piece. 4. Device according to claim 1, wherein the reference potential electrode is arranged at the lower end of the measuring probe. 5. Device according to claim 1, and wherein electric lines are arranged in the interior of the section of pipe. 6. Device according to claim 1, and wherein gaskets are provided between the parts which can be immersed into the filling material. 7. Device according to claim 1, and an additional measurement signal line is brought in contact with the resistance segment. 8. Device for filling containers such as bottles, and a device for detecting the filling level according to claim 1. 9. Method for detecting the filling level of a container such as a bottle with a measuring probe which comprises a resistance segment that is contacted electrically by a first contact and a second contact, and a longitudinal distance between the first contact and the second contact defines the resistance segment, comprising the steps: introducing the measuring probe into the container,filling the container increasingly, so that the resistance segment comes in contact with the filling material of the container in various filling levels,providing an electric reference potential by a reference potential electrode that is immersed in the filling material and is arranged on the measuring probe,applying a voltage between a first conductor connected to the first contact and a second conductor connected to the second contact to create a potential gradient between the first contact and the second contact such that with an increase in a filling level along the resistance segment, a potential of the filling material is changed, anddetecting the potential of the filling material by the reference potential electrode,wherein the resistance segment comprises a section of pipe, and wherein the lower end of the section of pipe is sealed with one of an insulation piece, the reference potential electrode, and a combination thereof, andwherein with the increase in the filling level, the reference potential electrode and then the lower end of the resistance segment is contacted by the filling material.
