Abstract

An apparatus ( 400 ) for a vibratory meter ( 100 ) having one or more flow tubes ( 101, 102 ) adapted to vibrate is provided. The apparatus ( 400 ) comprising two or more brace bars ( 203, 204 ) adapted to couple to the one or more flow tubes ( 101, 102 ), and an isolation bar ( 402 ) coupled to the two or more brace bars ( 203, 204 ).

First claim

What is claimed is:

1. An apparatus ( 400 ) for a vibratory meter ( 100 ) having one or more flow tubes ( 101 , 102 ) adapted to vibrate, comprising:
two or more brace bars ( 203 , 204 ) adapted to couple to the one or more flow tubes ( 101 , 102 ); and

an isolation bar ( 402 ) coupled to the two or more brace bars ( 203 , 204 ), wherein the isolation bar ( 402 ) includes an aperture ( 806 a ).

2. The apparatus ( 400 ) of claim 1 wherein the two or more brace bars ( 203 , 204 ) are coupled to the one or more flow tubes ( 101 , 102 ).

3. The apparatus ( 400 ) of claim 1 wherein the isolation bar ( 402 ) is adapted to isolate the vibratory meter ( 100 ).

4. The apparatus ( 400 ) of claim 3 wherein the isolation bar ( 402 ) is adapted to isolate the vibratory meter ( 100 ) by one or more parameters selected to isolate the vibratory meter ( 100 ).

5. The apparatus ( 400 ) of claim 4 wherein the one or more parameters selected includes a dimension of the isolation bar ( 402 ) selected to isolate the vibratory meter ( 100 ).

6. The apparatus ( 400 ) of claim 5 wherein the dimension of the isolation bar ( 402 ) selected to isolate the vibratory meter ( 100 ) is the width of the isolation bar ( 402 ).

7. The apparatus ( 400 ) of claim 5 wherein the dimension of the isolation bar ( 402 ) selected to isolate the vibratory meter ( 100 ) is a dimension of an aperture ( 806 a ) in the isolation bar ( 402 ).

8. The apparatus ( 400 ) of claim 1 wherein the isolation bar ( 402 ) is positioned to isolate the vibratory meter ( 100 ).

9. The apparatus ( 400 ) of claim 1 wherein the isolation bar ( 402 ) is adapted to isolate the one or more flow tubes ( 101 , 102 ).

10. The apparatus ( 400 ) of claim 1 wherein the isolation bar ( 402 ) comprises a flat plate adapted to isolate the vibratory meter ( 100 ).

11. The apparatus ( 400 ) of claim 1 further comprising a second isolation bar ( 502 ) coupled to the two or more brace bars ( 203 , 204 ).

12. A method for a vibratory meter ( 100 ) having one or more flow tubes ( 101 , 102 ) adapted to vibrate, comprising:
forming two or more brace bars ( 203 , 204 ) adapted to couple to the one or more flow tubes ( 101 , 102 );
forming and coupling an isolation bar ( 402 ) to the two or more brace bars ( 203 , 204 ); and
forming an aperture ( 806 a ) in the isolation bar ( 402 ).

13. The method of claim 12 further comprising coupling the two or more brace bars ( 203 , 204 ) to the one or more flow tubes ( 101 , 102 ).

14. The method of claim 12 wherein the forming and coupling the isolation bar ( 402 ) to the two or more brace bars ( 203 , 204 ) includes adapting the isolation bar ( 402 ) to isolate the vibratory meter ( 100 ).

15. The method of claim 14 wherein the adapting the isolation bar ( 402 ) includes selecting one or more parameters of the isolation bar ( 402 ) to isolate the vibratory meter ( 100 ).

16. The method of claim 15 wherein the selecting the one or more parameters of the isolation bar ( 402 ) includes selecting a dimension of the isolation bar ( 402 ) to isolate the vibratory meter ( 100 ).

17. The method of claim 16 wherein selecting the dimension of the isolation bar ( 402 ) to isolate the vibratory meter ( 100 ) comprises selecting a width of the isolation bar ( 402 ).

18. The method of claim 16 wherein the selecting the dimension of the isolation bar ( 402 ) to isolate the vibratory meter ( 100 ) comprises selecting a dimension of an aperture ( 806 a ) in the isolation bar ( 402 ).

19. The method of claim 12 wherein the forming and coupling the isolation bar ( 402 ) to the two or more brace bars ( 203 , 204 ) includes positioning the isolation bar ( 402 ) to isolate the vibratory meter ( 100 ).

20. The method of claim 12 wherein forming and coupling the isolation bar ( 402 ) to the two or more brace bars ( 203 , 204 ) includes isolating the one or more flow tubes ( 101 , 102 ).

21. The method of claim 12 wherein forming and coupling the isolation bar ( 402 ) to the two or more brace bars ( 203 , 204 ) includes isolating the vibratory meter ( 100 ).

22. The method of claim 12 further comprising forming and coupling a second isolation bar ( 502 ) to the two or more brace bars ( 203 , 204 ).

23. A vibratory meter ( 100 ) having one or more flow tubes ( 101 , 102 ), comprising:
two or more brace bars ( 203 , 204 ) coupled to the one or more flow tubes ( 101 , 102 ); and
an isolation bar ( 402 ) coupled to the two or more brace bars ( 203 , 204 ), wherein the isolation bar ( 402 ) includes an aperture ( 806 a ).

24. The vibratory meter ( 100 ) of claim 23 wherein the isolation bar ( 402 ) is adapted to isolate the vibratory meter ( 100 ).
