摘要：
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.
