Abstract

A field service device ( 280 ) for facilitating a processing system replacement in a vibratory flowmeter is provided. The field service device ( 280 ) includes a field service device processor ( 282 ) configured to interface with one or more vibratory flowmeter processing systems and a storage system ( 285 ) configured to store pre-replacement operationally-derived values ( 252 a ), post-replacement operationally-derived values ( 252 b ), and one or more scaling factors ( 266 ). The field service device processor ( 282 ) is configured to obtain pre-replacement operationally-derived values ( 252 a ), obtain post-replacement operationally-derived values ( 252 b ) after an old processing system has been replaced with a replacement processing system, generate the one or more scaling factors ( 266 ) as a ratio of one or more pre-replacement operationally-derived values ( 252 a ) to one or more post-replacement operationally-derived values ( 252 b ), and download the one or more scaling factors ( 266 ).

First claim

What is claimed is:

1. A field service device ( 280 ) for facilitating a processing system replacement in a vibratory flowmeter, with the field service device ( 280 ) comprising:
a field service device processor ( 282 ) configured to interface with one or more vibratory flowmeter processing systems, the one or more vibratory flowmeter processing systems including an electronics; and
a storage system ( 285 ) coupled to the field service device processor ( 282 ) and configured to store pre-replacement operationally-derived values ( 252 a ), post-replacement operationally-derived values ( 252 b ), and one or more scaling factors ( 266 );
with the field service device processor ( 282 ) being configured to obtain pre-replacement operationally-derived values ( 252 a ) of the vibratory flowmeter derived during operation of the vibratory flowmeter, obtain post-replacement operationally-derived values ( 252 b ) from the vibratory flowmeter after an old processing system has been replaced with a replacement processing system, generate the one or more scaling factors ( 266 ) as a ratio of one or more pre-replacement operationally-derived values ( 252 a ) to one or more post-replacement operationally-derived values ( 252 b ), and download the one or more scaling factors ( 266 ) into one or more of the replacement processing system ( 203 a ) or a monitoring computer, wherein the one or more scaling factors ( 266 ) corresponds to a gain difference through the electronics of the old processing system and the replacement processing system and can be used to process operationally-derived values ( 252 );
wherein the operationally-derived values ( 252 ) are at least one of meter calibration values and meter verification values.

2. The field service device ( 280 ) of claim 1 , further comprising retaining the one or more scaling factors ( 266 ) in the storage system ( 285 ) of the field service device ( 280 ).

3. The field service device ( 280 ) of claim 1 , with the storage system ( 285 ) further storing a data upload routine ( 246 ) for uploading the pre-replacement operationally-derived values ( 252 a ) from the old processing system, a scaling factor routine ( 249 ) for generating the one or more scaling factors ( 266 ), and a data download routine ( 247 ) for downloading the one or more scaling factors ( 266 ) into the replacement processing system ( 203 a ).

4. The field service device ( 280 ) of claim 1 , with obtaining the pre-replacement operationally-derived values comprising obtaining the pre-replacement operationally-derived values from the old processing system.

5. The field service device ( 280 ) of claim 1 , with obtaining the pre-replacement operationally-derived values comprising obtaining the pre-replacement operationally-derived values from a manufacturer's facility.

6. The field service device ( 280 ) of claim 1 , with the one or more scaling factors ( 266 ) being used to scale post-replacement operationally-derived values.

7. The field service device ( 280 ) of claim 1 , with the one or more scaling factors ( 266 ) being used to scale pre-replacement operationally-derived values.

8. The field service device ( 280 ) of claim 1 , with the one or more scaling factors ( 266 ) being used to scale vibratory flowmeter measurement values.

9. The field service device ( 280 ) of claim 1 , wherein the old processing system is replaced in the vibratory flowmeter by the replacement processing system before the scaling.

10. The field service device ( 280 ) of claim 1 , wherein the old processing system is replaced in the vibratory flowmeter by the replacement processing system after the scaling.

11. A processing system replacement method for a vibratory flowmeter, the method comprising:
obtaining pre-replacement operationally-derived values of the vibratory flowmeter derived during operation of the vibratory flowmeter;
replacing the old processing system having an electronics of the vibratory flowmeter with a replacement processing system having an electronics;
operating the vibratory flowmeter using the replacement processing system to generate post-replacement operationally-derived values;
generating one or more scaling factors as a ratio of one or more pre-replacement operationally-derived values to one or more post-replacement operationally-derived values, wherein the one or more scaling factors corresponds to a gain difference through the electronics of the old processing system and the replacement processing system; and
using the one or more scaling factors to process operationally-derived values;
wherein the operationally-derived values are at least one of meter calibration values and meter verification values.

12. The method of claim 11 , with obtaining the pre-replacement operationally-derived values comprising obtaining the pre-replacement operationally-derived values from the old processing system.

13. The method of claim 11 , with obtaining the pre-replacement operationally-derived values comprising obtaining the pre-replacement operationally-derived values from a manufacturer's facility.

14. The method of claim 11 , with the one or more scaling factors being used to scale post-replacement operationally-derived values.

15. The method of claim 11 , with the one or more scaling factors being used to scale pre-replacement operationally-derived values.

16. The method of claim 11 , with the one or more scaling factors being used to scale vibratory flowmeter measurement values.

17. The method of claim 11 , wherein the old processing system is replaced in the vibratory flowmeter by the replacement processing system before the scaling.

18. The method of claim 11 , wherein the old processing system is replaced in the vibratory flowmeter by the replacement processing system after the scaling.
