ABSTRACT:
The embodiment of the invention disclosed herein is directed to a monitoring system for detecting variations in the flow of a fluid through a passage such as an air duct associated with a cotton picker or other harvesting machine. Air flow sensing means is provided for mounting in the air duct to provide a first signal condition in response to the flow of air above a predetermined minimum level and a second signal condition in response to the flow of air below the predetermined minimum level. The air flow sensing means is coupled to an indicator means which attracts the attention of the harvesting machine operator and indicates which one, of a plurality of air ducts, is malfunctioning.
