Abstract

A control head of a fluid
measuring device ( 20, 40 ) has an outer housing ( 32 ) which has a surrounding shell surface ( 34 ), an open face side formed by a first opening ( 50 ) and facing the device ( 20, 30 ), an opposite open face side formed by a second opening ( 52 ), and a lateral opening ( 36 ) in the shell surface ( 34 ). The second opening ( 52 ) and the lateral opening ( 36 ) have substantially the same opening cross-section. The control head further has first and second closure units ( 60, 62 ) which each include a cover and a surrounding luminous ring ( 66 ) positioned on a housing side of the cover, the covers of the first and second closure units ( 60, 62 ) each being adapted to be configured as a blind cover ( 64 ) or as an electronic display ( 68 ), and each closure unit ( 60, 62 ) being adapted to be releasably coupled to the outer housing ( 32 ) both at the second opening ( 52 ) and at the lateral opening ( 36 ) to close the respective opening ( 36, 52 ).

First claim

The invention claimed is:

1. A control head of a fluid measuring device, comprising an outer housing which has a surrounding shell surface, an open face side formed by a first opening and facing the device, an opposite open face side formed by a second opening, and a lateral opening in the shell surface, the second opening and the lateral opening having substantially the same opening cross-section, and comprising first and second closure units which each include a cover and a surrounding luminous ring positioned on a housing side of the cover, the covers of the first and second closure units each being one of a blind cover and an electronic display, and each closure unit being adapted to be releasably coupled to the outer housing both at the second opening and at the lateral opening to close the respective opening,
wherein each luminous ring includes a continuously surrounding transparent outer ring having at least one light-conducting extension adjoining it on an inside, and protruding radially inwards.

2. The control head according to claim 1 , wherein at least one light conducting extension is molded integrally with the transparent outer ring.

3. The control head according to claim 1 , wherein the outer ring is a separate part which is configured as a sealing ring and is axially clamped between the cover and the outer housing.

4. The control head according to claim 1 , wherein a transparent light distributor protrudes into the luminous ring at least in sections and constitutes a part that is separate from the luminous ring and has light entry surfaces and light exit surfaces opposite the light-conducting extension.

5. A control head of a fluid measuring device, comprising an outer housing which has a surrounding shell surface, an open face side formed by a first opening and facing the device, an opposite open face side formed by a second opening, and a lateral opening in the shell surface, the second opening and the lateral opening having substantially the same opening cross-section, and comprising first and second closure units which each include a cover and a surrounding luminous ring positioned on a housing side of the cover, the covers of the first and second closure units each being one of a blind cover and an electronic display, and each closure unit being adapted to be releasably coupled to the outer housing both at the second opening and at the lateral opening to close the respective opening,
wherein one mounting ring which is fitted to the outer housing is provided between the luminous ring and the second opening and a further mounting ring is provided between the luminous ring and the lateral opening,
wherein the mounting rings have fastening geometries by means of which the closure units are fastened to the outer housing,
wherein the luminous rings have fastening geometries molded integrally therewith by means of which the closure units are fitted to the outer housing so as to be nondestructively releasable, and
wherein the luminous rings have bayonet closure geometries molded integrally therewith to form bayonet closures with mating geometries on the mounting rings.

6. A control head of a fluid measuring device, comprising an outer housing which has a surrounding shell surface, an open face side formed by a first opening and facing the device, an opposite open face side formed by a second opening, and a lateral opening in the shell surface, the second opening and the lateral opening having substantially the same opening cross-section, and comprising first and second closure units which each include a cover and a surrounding luminous ring positioned on a housing side of the cover, the covers of the first and second closure units each being one of a blind cover and an electronic display, and each closure unit being adapted to be releasably coupled to the outer housing both at the second opening and at the lateral opening to close the respective opening,
wherein a plurality of lamps are provided in the outer housing in the region of the second opening and are optically coupled to the luminous ring.
