Method and apparatus for detecting a liquid spray pattern
During a liquid spray pattern detection procedure, the sensor ( 50, 52 ) is operable to detect the presence or absence of an edge of the dispensed liquid spray pattern. The nozzle ( 18 ) of the liquid dispensing system is moved to a predetermined position (A) relative to the sensor ( 50, 52 ) to det...

Summary: | During a liquid spray pattern detection procedure, the sensor ( 50, 52 ) is operable to detect the presence or absence of an edge of the dispensed liquid spray pattern. The nozzle ( 18 ) of the liquid dispensing system is moved to a predetermined position (A) relative to the sensor ( 50, 52 ) to determine the presence or absence of the spray pattern and is then moved to a second predetermined position (B) relative to the sensor ( 50, 52 ) to again determine the presence or absence of the spray pattern. Based on these determinations, the width of the spray pattern can be verified. This provides a quick means to verify that the width of the dispensed pattern is within certain tolerances. |
