    摘要: Methods and systems for measuring a gas flow rate and/or a solids feed rate by detecting a vibroacoustic emission caused by passage of the gases and/or solids through an interior of a pipe are described. The methods include correlating an intensity of a broad-band vibroacoustic emission having a frequency of up to 3,200 Hz with a change in the gas flow rate. The methods also include correlating a change in a position of a narrow-band vibroacoustic emission having a frequency of up to 800 Hz with a change in the solids feed rate. The methods further include correlating the change in the position of the narrow-band vibroacoustic emission with an absolute solids feed rate. The systems include at least one vibroacoustic sensor and at least one computer program product having machine-readable instructions executable on at least one processor for performing the described steps of correlating.
