Abstract

A device for determining the fill level of a medium in a container has at least one electronic device and at least one signal conductor arrangement. The electronic device supplies the signal conductor arrangement with electromagnetic signals. To provide a device for determining the fill level that is advantageous compared to the prior art, the signal conductor arrangement has several emitting devices for emitting the electromagnetic signal. A support element that can be inserted in a wall of the container supports the signal conductor arrangement.

First claim

What is claimed is:

1. A device for determining a fill level of a medium in a container, comprising:
at least one electronic device and
at least one signal conductor arrangement,
wherein the electronic device supplies the at least one signal conductor arrangement with electromagnetic signals,
wherein the signal conductor arrangement has a plurality emitting devices for emitting the electromagnetic signals,
wherein a support element supports the signal conductor arrangement,
wherein the support element is insertable in a side wall of the container which extends between a top wall and a bottom wall of the container,
wherein the emitting devices are located at least in part on a side of the support element facing into the container in the mounted state, and
wherein the at least one signal conductor arrangement also comprises a plurality of individual sensors that are operable individually and supply individual measured values which enable fill level determinations, the sensors being located together with the emitters on said support element.

2. The device according to claim 1 , wherein at least one of the emitting devices is an antenna or a patch antenna.

3. The device according to claim 1 , wherein at least a part of the emitting device is arranged essentially rotationally symmetric around at least one emitting device that is centrally arranged in relation to the support element.

4. The device according to claim 1 , wherein at least two of the emitting devices are attached at the same level in relation to a longitudinal axis of the support element.

5. The device according to claim 1 , wherein at least two of the emitting devices are attached at different levels in relation to a longitudinal axis of the support element and height of the container.

6. The device according to claim 1 , wherein the support element is essentially configured as a circular disk.

7. The device according to claim 1 , wherein the support element has an outer surface with an outer threading.

8. The device according to claim 1 , wherein the support element is sealingly insertable in the side wall of the container.

9. The device according to claim 1 , wherein the support element is formed at least in part of a multi-layer ceramic and wherein at least a part of the emitting devices is arranged between the layers of the multi-layer ceramic.

10. The device according to claim 1 , wherein the device has a construction suitable for use in zones at risk for explosion.

11. The device according to claim 1 , wherein the emitting devices are protected by at least one dielectric protective layer.

12. The device according to claim 1 , wherein the support is flange-shaped.
