Abstract

A system, method, and apparatus for attenuating acoustic back-coupling in a ultrasonic meter transducer that includes a gasket band comprising a loop of a material, a first gasket ring integrated in the gasket band configured to match a diameter of a first bracket hole, and a second gasket ring integrated in the gasket band configured to match a diameter of a second bracket hole wherein the loop of material comprises a material that provides both environmental sealing and acoustic attenuation.

First claim

What is claimed is:

1. An apparatus comprising:
a gasket band comprising a loop of a material;
a bracket wherein said gasket band is configured to match a shape of a rim of said gasket;
a first gasket ring integrated in said gasket band configured to match a diameter of a first bracket hole; and
a second gasket ring integrated in said gasket band configured to match a diameter of a second bracket hole wherein said loop of material comprises a material that provides environmental sealing and acoustic attenuation,
wherein said bracket comprises a mounting bracket for an ultrasonic meter transducer.

2. The apparatus of claim 1 wherein said material comprises at least one of:
crosslinked polyethylene;
polyether urethane;
Neoprene; and
polymer said polymer comprising (NBR/PVC).

3. The apparatus of claim 1 wherein said bracket further comprises:
a recessed rim, said recessed rim being shaped to match a gasket band shape and a gasket band width, said first gasket ring shape, and said second gasket ring shape, wherein a prescribed portion of said gasket band, said first gasket ring, and said second gasket ring extend above a surface of said bracket by a prescribed dimension.

4. The apparatus of claim 1 wherein at least one of a thickness and a width of said gasket band, said first gasket ring, and said second gasket ring are selected according to a portion of a wavelength of said gasket material and an associated ultrasonic metering transducer.

5. The apparatus of claim 1 further comprising:
a third gasket ring configured between said first gasket ring and said second gasket ring; and
at least one gasket arm connecting said third gasket ring to said gasket band.

6. An system comprising:
a gasket band comprising a loop of a material;
a bracket wherein said gasket band is configured to match a shape of a rim of said gasket;
a first gasket ring integrated in said gasket band configured to match a diameter of a first bracket hole; and
a second gasket ring integrated in said gasket band configured to match a diameter of a second bracket hole wherein said loop of material comprises a material that provides environmental sealing and acoustic attenuation.

7. The system of claim 6 wherein said material comprises at least one of:
crosslinked polyethylene;
polyether urethane;
Neoprene; and
polymer said polymer comprising (NBR/PVC).

8. The system of claim 6 further comprising an ultrasonic meter wherein said bracket comprises a mounting bracket for an ultrasonic meter transducer.

9. The system of claim 6 wherein said bracket further comprises:
a recessed rim, said recessed rim being shaped to match a gasket band shape and a gasket band width, said first gasket ring shape, and said second gasket ring shape, wherein a prescribed portion of said gasket band, said first gasket ring, and said second gasket ring extend above a surface of said bracket by a prescribed dimension.

10. The system of claim 6 wherein at least one of a thickness and a width of said gasket band, said first gasket ring, and said second gasket ring are selected according to a portion of a wavelength of an associated ultrasonic metering transducer.

11. The system of claim 6 further comprising:
a third gasket ring configured between said first gasket ring and said second gasket ring; and
at least one gasket arm connecting said third gasket ring to said gasket band.

12. A back-coupling attenuation method, said method comprising:
determining a wavelength associated with an ultrasonic meter transducer;
configuring a gasket according to said wavelength of said ultrasonic meter transducer;
selecting a material of said gasket according to said wavelength of said ultrasonic meter transducer; and
connecting said ultrasonic meter transducer to a gas distribution device with a bracket, said gasket being formed between said bracket and said gas distribution thereby providing environmental sealing and acoustic attenuation.

13. The method of claim 12 wherein said material of said gasket comprises at least one of:
crosslinked polyethylene;
polyether urethane;
Neoprene; and
polymer said polymer comprising (NBR/PVC).

14. The method of claim 12 further comprising:
configuring said gasket band to match a shape of a rim of said gasket;
configuring a first gasket ring integrated in said gasket band to match a diameter of a first bracket hole in said bracket; and
configuring a second gasket ring integrated in said gasket band to match a diameter of a second bracket hole.

15. The method of claim 14 further comprising:
forming a recessed rim, said recessed rim being shaped to match a gasket band shape and a gasket band width, said first gasket ring shape, and said second gasket ring shape, wherein a prescribed portion of said gasket band, said first gasket ring, and said second gasket ring extend above a surface of said bracket by a prescribed dimension.

16. The method of claim 14 wherein configuring said gasket according to said wavelength of said ultrasonic meter transducer further comprises:
configuring a thickness of said gasket band, said first gasket ring, and said second gasket ring according to a portion of said wavelength of said ultrasonic metering transducer.

17. The method of claim 14 wherein configuring said gasket according to said wavelength of said ultrasonic meter transducer further comprises:
configuring a width of said gasket band, said first gasket ring, and said second gasket ring according to a portion of said wavelength of said ultrasonic metering transducer.

18. The method of claim 14 further comprising:
forming a third gasket ring configured between said first gasket ring and said second gasket ring; and
connecting said third gasket ring to said gasket band with at least one gasket arm with.
