System and method for preventing false flow measurements in a vibrating meter

A fluid flow system (300), comprising:

• a pipeline (301);
• at least one fluid switch located within the pipeline (301) and determining one of one or more fluid conditions within the pipeline (301), wherein a first fluid switch (309) of the at least one fluid switch comprises a fluid level switch wherein a first fluid switch signal (214) indicates that a liquid fill level within the pipeline (301) is outside a threshold value or band;
• a vibrating meter (5) including:
• a sensor assembly (10) located within the pipeline (301) proximate to and in fluid communication with the first fluid switch (309);
• and
• a meter electronics (20) in electrical communication with the sensor assembly (10) to receive one or more sensor signals (210) and measure one or more flow characteristics, wherein a flow characteristic of the one or more flow characteristics comprises a mass flow rate;
• a system controller (317) in electrical communication with the first fluid switch (309) and in electrical communication with the meter electronics (20) and configured to:
• receive the one or more measured flow characteristics from the meter electronics (20);
• receive the first fluid switch signal (214) indicating one of the one or more fluid conditions within the pipeline (301) from the first fluid switch (309);
• and
• correct at least one of the one or more flow characteristics measured by the meter electronics if a fluid condition of the one or more fluid conditions is outside a threshold value or band.
