Abstract

The flowmeter having at least one measuring tube and having at least one inlet element, wherein the inlet element is connected to the at least one measuring tube and is arranged before the at least one measuring tube in respect to flow direction. The flowmeter that is also suitable for the verification of erosive media is achieved in that at least one inflow element is provided, wherein the inflow element is arranged at least partly within the inlet element and wherein the inflow element is detachably connectable to the inlet element.

First claim

What is claimed is:

1. A flowmeter, comprising:
at least one measuring tube and
at least one inlet element,
wherein the inlet element is connected to the at least one measuring tube and is arranged before the at least one measuring tube in respect to a direction of flow,
wherein at least one inflow element is arranged at least partially within the inlet element,
wherein the inflow element is detachably connectable to the inlet element, and
wherein the flowmeter is a Coriolis mass flowmeter with at least one oscillation generator and with at least two oscillation sensors.

2. The flowmeter according to claim 1 , wherein the inflow element is connected to the inlet element by means of a force-fit or a form-fit connection.

3. The flowmeter according to claim 1 , wherein the inflow element is connected to the inlet element by means of screwing, clamping or adhesive.

4. The flowmeter according to claim 1 , wherein the inflow element is formed at least partially of a metal or a polymer.

5. The flowmeter according to claim 1 , wherein a flange element is provided for attachment to external piping and wherein the inflow element is arranged at least partially within the flange element.

6. The flowmeter according to claim 1 , wherein a flange element is provided for attachment to external piping and wherein the inflow element is arranged between the flange element and the at last one measuring tube.

7. The flowmeter according to claim 1 , wherein the inflow element is a flow cross section reducer.

8. The flowmeter according to claim 1 , wherein a flow cross section reducer is arranged within the inlet element and wherein the inflow element is a protective shield on the flow cross section reducer.

9. Flowmeter according to claim 8 , wherein a flange element is provided for attachment to external piping, wherein the protective shield is arranged at least partially within the flange element and wherein the protective shield has a protective shield flange.

10. Flowmeter according to claim 8 , wherein the protective shield has is a flow splitter or a flow cross section reducer.

11. The flowmeter according to claim 1 , wherein said at least one measuring tube comprises at least two measuring tubes, wherein a flow splitter is provided and wherein the inflow element a protective shield\arranged on the flow splitter.

12. The flowmeter according to claim 11 , wherein the flow splitter is arranged before the at least two measuring tubes relative to a flow direction within the inlet element.

13. A flowmeter, comprising:
at least one measuring tube and
at least one inlet element,
wherein the inlet element is connected to the at least one measuring tube and is arranged before the at least one measuring tube in respect to a direction of flow,
wherein the inflow element is detachably connectable to the inlet element, and
wherein at least two measuring tubes are provided and that the inflow element is designed as flow splitter, which is preferably arranged within the inlet element before the measuring tube in respect to flow direction.
