An error detection and flow rate monitoring system of a liquid fertilizerdistribution system of an agricultural implement that can provide feedback toidentifycompromised flow states in the system and corresponding locations of potentialblockageor component failure. The system may include pressure sensors that may beevaluated inpairs or otherwise analyzed comparatively to determine flow rate or othercharacteristicsthrough nozzle assemblies. The pressure sensors may be mounted in the wet boombetween the rows. A control system compares the pressure values before andafter eachrow to determine the pressure drop across its nozzle assembly and may furtheruse thepressure drop values to determine flow or application rates and correspondingerrors inthe pressure drop, flow rate, and application rate compared to theiracceptable values andmay provide feedback to identify a specific location(s) of potential blockageor flow-controlcomponent failure.
