Patent ID: 7953568

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 first and second pickoff sensors ( 201 a and 201 b ) and the cabling ( 205 ) coupled to the first and second pickoff sensors ( 201 a , 201 b ) and including one or more first pickoff wires and one or more second pickoff wires, with the meter electronics ( 20 ) being characterized by: a signal injection device ( 203 ) coupled to the cabling ( 205 ), with the signal injection device ( 203 ) being configured to generate an injection signal and communicate the injection signal into the cabling ( 205 ) and to the first and second pickoff sensors ( 201 a , 201 b ); 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 injection signal and determine one or more of a pickoff open wire fault and a pickoff connection orientation fault in one or both of the one or more first pickoff wires and the one or more second pickoff wires of the cabling ( 205 ).
