Abstract

A housing arrangement for a flow meter that has at least one housing ( 2 ) and at least one display device ( 3 ) which is located on the housing ( 2 ). The maintenance effort for the flow meter is reduced by there being at least one photovoltaic cell on the housing in a manner configured and arranged surrounding the at least one display device.

First claim

What is claimed is:

1. A housing arrangement for a flow meter, comprising:
at least one housing for flow metering electronics of the meter and
at least one display device which is located on the housing for displaying values produced by the flow metering electronics,
wherein at least one photovoltaic cell is mounted to the housing in at least a position in a manner configured and arranged surrounding the at least one display device,
wherein at least the photovoltaic cell is mounted to be able to swivel around at least one axis relative to the display device and
wherein the display device can be viewed through the photovoltaic cell in swiveled positions thereof.

2. The housing arrangement as claimed in claim 1 , wherein the photovoltaic cell has a recess which corresponds at least to the size of the of the at least one display device.

3. The housing arrangement as claimed in claim 1 , wherein the photovoltaic cell is annular.

4. The housing arrangement as claimed in claim 1 , wherein the photovoltaic cell is mounted to be able to swivel around at least two axes.

5. The housing arrangement as claimed in claim 1 , wherein the photovoltaic cell is pivotally mounted with reference to a plane of the photovoltaic cell.

6. The housing arrangement as claimed in claim 1 , wherein the photovoltaic cell is mounted to be able to be moved by at least one servo.

7. The housing arrangement as claimed in claim 1 , wherein the photovoltaic cell is integrated into the housing.

8. The housing arrangement as claimed in claim 7 , wherein the photovoltaic cell is surrounded by the housing and located behind a transparent display glass of the at least one display device.

9. The housing arrangement as claimed in claim 1 , wherein at least one cover ring is provided on the housing and wherein the photovoltaic cell is located in the cover ring.

10. The housing arrangement as claimed in claim 1 , wherein said at least one photovoltaic cell has a first position located parallel to a plane in which the display is located and at least one second position pivoted out of the plane in which the display is located.

11. A flow meter, comprising:
a housing arrangement having at least one housing for flow metering electronics of the meter,
at least one display device which is located on the housing for displaying values produced by the flow metering electronics, and
at least one photovoltaic cell mounted to the housing in a manner configured and arranged surrounding the display device for powering electronics of the meter,
wherein at least the photovoltaic cell is mounted to be able to swivel around at least one axis relative to the display device and wherein displayed values are viewable through the photovoltaic cell in swiveled positions of the photovoltaic cell.

12. A flow meter according to claim 11 , wherein the photovoltaic cell is surrounded by the housing and located behind transparent display glass of the at least one display.
