ABSTRACT:
A monitoring assembly for a filter includes an acoustic apparatus. The acoustic apparatus includes a first receiver, a second receiver, a resonator, and a transmitter. The transmitter is configured to emit sound waves receivable by at least one of the first receiver, the second receiver, and the resonator. The monitoring assembly also includes an electronic control module configured to receive signals from at least one of the first and second receivers.
