Abstract

A sensor assembly (10) of a vibrating meter (5) is provided. The sensor assembly (10) comprises one or more fluid conduits (103A, 103B). The sensor assembly (10) also includes a case (200) surrounding at least a portion of the one or more fluid conduits (103A, 103B). A synthetic wrap (300) is applied to at least a portion of the case (200).

First claim

We claim:

1. A sensor assembly ( 10 ) of a vibrating meter ( 5 ), comprising:
one or more fluid conduits ( 103 A, 103 B);
a case ( 200 ) surrounding at least a portion of the one or more fluid conduits ( 103 A, 103 B); and
a synthetic wrap ( 300 ) applied to at least a portion of the case ( 200 ) to increase a natural frequency of the case ( 200 ), and the synthetic wrap ( 300 ) applied to another portion of the case ( 200 ) to lower the natural frequency of the case.

2. The sensor assembly ( 10 ) of claim 1 , wherein the synthetic wrap ( 300 ) is applied to substantially the entire outer surface of the case ( 200 ).

3. The sensor assembly ( 10 ) of claim 1 , wherein the synthetic wrap ( 300 ) comprises a synthetic fiber.

4. The sensor assembly ( 10 ) of claim 3 , wherein fibers of the synthetic wrap ( 300 ) are oriented to adjust one or more vibrational frequencies of the case ( 200 ).

5. The sensor assembly ( 10 ) of claim 3 , wherein the synthetic wrap ( 300 ) comprises two or more different synthetic fibers.

6. The sensor assembly ( 10 ) of claim 1 , wherein the synthetic wrap is applied at a first thickness to a first portion of the case and at least a second thickness to at least a second portion of the case.

7. A method for forming a sensor assembly of a vibrating meter including one or more fluid conduits, comprising steps of:
surrounding at least a portion of the one or more fluid conduits with a case; and
applying a synthetic wrap to at least a portion of the case to increase a natural frequency of the case, and the synthetic wrap applied to another portion of the case to lower the natural frequency of the case.

8. The method of claim 7 , wherein the step of applying the synthetic wrap comprises applying the synthetic wrap to substantially the entire outer surface of the case.

9. The method of claim 7 , wherein the synthetic wrap comprises a synthetic fiber.

10. The method of claim 9 , wherein the step of applying the synthetic wrap comprises orienting the fibers of the synthetic wrap to adjust one or more vibrational frequencies of the case.

11. The method of claim 9 , wherein the synthetic wrap comprises two or more different synthetic fibers.

12. The method of claim 7 , wherein the step of applying the synthetic wrap comprises pre-tensioning the synthetic wrap.

13. The method of claim 7 , wherein the step of applying the synthetic wrap comprises applying more than one layer of the synthetic wrap.

14. The method of claim 7 , wherein the step of applying the synthetic wrap comprises applying the synthetic wrap at a first thickness to a first portion of the case and at least a second thickness to at least a second portion of the case.
