Abstract

Systems and methods for temperature compensation in a utility meter are provided. According to one embodiment of the disclosure, there is disclosed a method. The method can include receiving, from a sensor of a device, a temperature and a current associated with a first portion of the device. The method can also include determining, based at least in part on a correlation between at least one prior measured temperature and current associated with the first portion of the device and a prior measured temperature and current associated with a second portion of the device, a predicted temperature associated with the second portion of the device.

First claim

The claimed invention is:

1. A system, comprising:
at least one memory that stores non-transitory computer-executable instructions;
at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to:
receive, from a sensor of a utility meter, at least one temperature and a current associated with a first portion of the utility meter, wherein a single sensor module receives the temperature and current associated with the first portion of the utility meter;
determine, based at least in part on a correlation between at least one prior measured temperature and current associated with the first portion of the utility meter and a prior measured temperature and current associated with a second portion of the utility meter, a predicted temperature associated with the second portion of the utility meter; and
adjust, based at least in part on the predicted temperature associated with the second portion of the utility meter, a data output associated with the utility meter, wherein the data output comprises energy consumption data.

2. The system of claim 1 , wherein the first portion of the device comprises a first compartment of the device, and the second portion of the device comprises a second compartment of the device.

3. The system of claim 2 , wherein the predicted temperature, from the correlation, associated with the second portion of the device is used to adjust a data output associated with the second portion of the device.

4. The system of claim 1 , wherein a temperature sensor is located within the first compartment of the device.

5. The system of claim 1 , wherein the device comprises a utility meter or an energy meter.

6. The system of claim 3 , wherein the data output comprises energy consumption data.

7. The system of claim 1 , wherein the correlation between the at least one prior measured temperature and current associated with the first portion and at least one prior measured temperature and current associated with the second portion is measured at different predefined time intervals.

8. The system of claim 1 , wherein the correlation comprises at least one of the following: a look-up table, a graph, a transfer function, or a series of temperatures and currents associated with the first portion of the device and the second portion of the device for different predefined time intervals.

9. A method, comprising:
receiving, from a sensor of a utility meter, a temperature and a current associated with a first portion of the utility meter;
determining, based at least in part on a correlation between at least one prior measured temperature and current associated with the first portion of the utility meter and a prior measured temperature and current associated with a second portion of the utility meter, a predicted temperature associated with the second portion of the utility meter; and
adjusting, based at least in part on the predicted temperature associated with the second portion of the utility meter, a data output associated with the utility meter, wherein the data output comprises energy consumption data.

10. The method of claim 9 , wherein the first portion of the device comprises a first compartment of the device, and the second portion of the device comprises a second compartment of the device.

11. The method of claim 10 , wherein the predicted temperature, from the correlation, associated with the second portion of the device is used to adjust a data output associated with the second portion of the device.

12. The method of claim 9 , wherein the sensor is located within a first compartment of the device.

13. The method of claim 9 , wherein the correlation between the at least one prior measured temperature and current of the first portion and the at least one prior measured temperature and current associated with the second portion of the device is measured at different predefined time intervals.

14. The method of claim 9 , wherein the correlation comprises at least one of the following: a look-up table, a graph, a transfer function, or a series of temperatures and currents associated with the first portion of the device and the second portion of the device for different predefined time intervals.

15. One or more non-transitory computer readable media containing computer instructions stored therein for causing a computer processor to perform operations comprising:
receiving, from a sensor of a utility meter, a temperature of a first portion of the utility meter;
receiving, from a sensor of the utility meter, a current associated with the first portion of the utility meter;
determining, based at least in part on a correlation of a prior measured temperature and current associated with the first portion and a prior measured temperature and current associated with a second portion of the utility meter, a predicted temperature associated with the second portion of the utility meter; and
adjusting, based at least in part on the predicted temperature associated with the second portion of the utility meter, a data output associated with the utility meter, wherein the data output comprises energy consumption data.

16. The one or more computer-readable media of claim 15 , wherein the first portion comprises a first compartment, and the second portion comprises a second compartment.

17. The one or more computer-readable media of claim 15 , wherein the operations further comprise:
based at least in part on the predicted temperature associated with the second portion, adjusting a data output associated with the utility meter.

18. The one or more computer-readable media of claim 15 , wherein the correlation comprises at least one of the following: a look-up table, a graph, a transfer function, or a series of temperatures and currents associated with the first portion of the utility meter and the second portion of the utility meter for different predefined time intervals.
