Patent ID: 8135552

Claim:
A meter electronics ( 20 ) for detecting a cable fault in a cabling ( 205 ) of a flow meter ( 5 ), with the meter electronics ( 20 ) including a driver ( 204 ), first and second pickoff sensors ( 201 a , 201 b ), and the cabling ( 205 ) coupled to the first and second pickoff sensors ( 201 a , 201 b ) and to the driver ( 204 ), with the meter electronics ( 20 ) being characterized by: a driver circuit ( 220 ) coupled to the cabling ( 205 ) and configured to generate a drive signal and communicate the drive signal into the cabling ( 205 ) and to the driver ( 204 ); and a signal conditioning circuit ( 202 ) coupled to the cabling ( 205 ), with the signal conditioning circuit ( 202 ) being configured to receive at least one response signal from at least one of the first and second pickoff sensors ( 201 a , 201 b ) in response to the drive signal and determine one or more of a driver open wire fault and a driver connection orientation fault in one or more driver wires of the cabling ( 205 ).
