Abstract

A meter electronics (100) for two or more meter assemblies (10a, 10b). The meter electronics (100) includes a processor (110) and one or more signal processors (120) communicatively coupled to the processor (110). The one or more signal processors (120) are configured to communicatively couple to a first meter assembly (10a) and a second meter assembly (10b). Accordingly, only one meter electronics can be employed to control the two or more meter assemblies, which may reduce the costs associated with employing two meter electronics.

First claim

1 . A meter electronics ( 100 ) for two or more meter assemblies ( 10 a , 10 b ), the meter electronics ( 100 ) comprising:
a processor ( 110 ); and one or more signal processors ( 120 ) communicatively coupled to the processor ( 110 ), wherein the one or more signal processors ( 120 ) are configured to communicatively couple to a first meter assembly ( 10 a ) and a second meter assembly ( 10 b ).

2 . The meter electronics ( 100 ) of claim 1 , wherein the one or more signal processors ( 120 ) are further configured to receive a first sensor signal ( 12 a ) from the first meter assembly ( 10 a ) and a second sensor signal ( 12 b ) from the second meter assembly ( 10 b ).

3 . The meter electronics ( 100 ) of claim 2 , wherein the one or more signal processors ( 120 ) are further configured to digitize the first sensor signal ( 12 a ) and the second sensor signal ( 12 b ).

4 . The meter electronics ( 100 ) of claim 1 , wherein the one or more signal processors ( 120 ) are further configured to provide a first drive signal ( 14 a ) to a first meter assembly ( 10 a ) and a second drive signal ( 14 b ) to a second meter assembly ( 10 b ).

5 . The meter electronics ( 100 ) of claim 1 , further comprising a communication port ( 140 ) communicatively coupled to the processor ( 110 ), wherein the communication port ( 140 ) is configured to communicatively couple with a host.

6 . The meter electronics ( 100 ) of claim 1 , wherein the one or more signal processors ( 120 ) are configured to receive the first sensor signal ( 12 a ) via a first communication channel ( 112 a ) and the second sensor signal ( 12 b ) via a second communication channel ( 112 b ).

7 . The meter electronics ( 100 ) of claim 1 , wherein the first sensor signal ( 12 a ) is comprised of signals from a left pick-off sensor ( 17 al , 17 bl ) and a right pick-off sensor ( 17 ar , 17 br ) in the first meter assembly ( 10 a ) and the second sensor signal ( 12 b ) is comprised of signals from a left pick-off sensor ( 17 al , 17 bl ) and a right pick-off sensor ( 17 ar , 17 br ) in the second meter assembly ( 10 b ).

8 . The meter electronics ( 100 ) of claim 1 , further comprising at least one memory ( 130 ) communicatively coupled to the processor ( 110 ).

9 . A method of operating two or more meter assemblies, the method comprising:
providing a first sensor signal, the first sensor signal being provided by a first meter assembly; providing a second sensor signal, the second sensor signal being provided by a second meter assembly; and receiving the first sensor signal and the second sensor signal with a meter electronics.

10 . The method of claim 9 , further comprising:
providing a first drive signal to the first meter assembly; and providing a second drive signal to the second meter assembly; wherein the first drive signal and the second drive signal are provided by the meter electronics.

11 . The method of claim 9 , further comprising digitizing the first sensor signal and the second sensor signal with at least one signal processor.

12 . The method of one claim 9 , wherein the first and second sensor signal is provided to the meter electronics through a first communication channel and the second sensor signal is provided through a second communication channel.

13 . The method of claim 9 , wherein the first sensor signal is comprised of signals from a left pick-off sensor and a right pick-off sensor in the first meter assembly and the second sensor signal is comprised of signals from a left pick-off sensor and a right pick-off sensor in the second meter assembly.

14 . A system ( 5 ) with meter electronics ( 100 ) for two or more meter assemblies, the system ( 5 ) comprising:
a first meter assembly ( 10 a ); a second meter assembly ( 10 b ); and a meter electronics ( 100 ) communicatively coupled to the first meter assembly ( 10 a ) and the second meter assembly ( 10 b ).

15 . The system ( 5 ) of claim 14 , wherein the first meter assembly ( 10 a ) is configured to measure one of a property and a characteristic of a fluid in a supply line (SL) and the second meter assembly ( 10 b ) is configured to measure one of a property and a characteristic of a fluid in a return line (RL).
