Abstract

An erosion-resistant insert is provided for a flow measurement device having a fluid displacement member. The insert includes a flange and a sleeve extending axially from the flange. The sleeve may be inserted into a recess machined into a fluid conduit of the fluid measurement device to protect the inner wall of the conduit. The insert maintains a property of the flow measurement device.

Claims (31)

1. A system, comprising:

a flow measurement device;

an erosion-resistant insert configured to removably couple to the flow measurement device, the erosion-resistant insert comprising:

a flanged portion; and

a sleeve portion configured to extend into a fluid conduit of the flow measurement device and maintain a property of the flow measurement device, wherein the sleeve portion comprises an erosion-resistant material.

2. The system of claim 1 , wherein the sleeve portion has an inner diameter equal to a first inner diameter of the fluid conduit.

3. The system of claim 1 , wherein the property comprises a beta ratio of the flow measurement device.

4. The system of claim 1 , wherein the flow measurement device comprises a fluid displacement member defines having a peripheral edge separating an upstream sloping surface from a downstream sloping surface.

5. The system of claim 4 , wherein the erosion-resistant insert extends at least around the peripheral edge of the fluid displacement member.

6. The system of claim 4 , wherein the erosion-resistant insert extends around the fluid displacement member.

7. The system of claim 1 , wherein the flow measurement device comprises a Pitot tube.

8. The system of claim 5 , wherein the erosion-resistant insert extends around the Pitot tube.

9. The system of claim 1 , wherein the flow measurement device comprises a vortex meter.

10. The system of claim 9 , wherein the vortex meter comprises a buff body and the erosion-resistant insert extends around the buff body.

11. The system of claim 1 , wherein the erosion-resistant material comprises stellite, tungsten carbide, or cemented carbide.

12. A system, comprising:

an erosion-resistant insert for a flow measurement device, comprising:

a flanged portion; and

a sleeve portion extending axially from the flanged portion, wherein the sleeve portion is configured to insert into a fluid conduit of the flow measurement device and maintain a property of the flow measurement device.

13. The system of claim 12 , wherein the property comprises a beta ratio of the flow measurement device.

14. The system of claim 12 , wherein the sleeve portion comprises stellite, tungsten carbide, or cemented carbide.

15. The system of claim 12 , wherein the sleeve portion comprises an axial slot.

16. The system of claim 12 , wherein the flanged portion comprises stellite, tungsten carbide, or cemented carbide.

17. A method, comprising:

inserting an erosion-resistant insert into a recess of a conduit of a flow measurement device, wherein the insert comprises a sleeve portion and a flange portion, wherein the sleeve portion comprises an erosion-resistant material.

18. The method of claim 17 , comprising maintaining a beta ratio of the flow measurement device by inserting the erosion-resistant insert into the recess.

19. The method of claim 17 , comprising measuring the flow rate of a fluid flowing through the conduit of the flow measurement device.

20. The system of claim 19 , wherein the fluid comprises oil, natural gas, or steam.

21. The system of claim 12 , wherein the erosion-resistant insert is rigid.

22. The system of claim 12 , wherein the sleeve portion is rigid, and the sleeve portion is formed from an erosion-resistant material.

23. The system of claim 12 , wherein the sleeve portion is formed from the erosion-resistant material.
