Abstract
In an embodiment, a system for measuring material flow in a pipe is disclosed. A first transducer is operable to transmit a first signal having a first frequency at a first time and receive a second signal at a second time, and a second transducer spaced apart from the first transducer and is operable to receive the first signal and transmit the second signal having the first frequency. A signal processing circuit communicatively coupled to the first transducer and the second transducer, the signal processing circuit is operable to determine a first envelope of the first signal and a second envelope of the second signal and calculate a flow rate based on the first envelope of the first signal and the second envelope of the second signal.
