Abstract
A particulate flow monitor for a pneumatic system including a particulate flow tube defining a particulate flow path, a blower connected to the flow tube and the flow tube terminating at a particulate discharge, which flow monitor comprises an acoustic transducer connected to the flow tube intermediate the blower and the discharge; said acoustic transducer being located in said particulate flow path; an impact surface on said acoustic transducer adapted for being impacted by the particulate matter in said flow path; and an electrical signal generator connected to said acoustic transducer and adapted for generating an electrical signal in response to sound waves created by particulate matter impact; said signal generator including an output adapted for providing an electrical output signal corresponding to said sound waves; and a processor connected to said signal generator output; and said processor being programmed to monitor particulate flow based on said detected particulate matter impact.
