ABSTRACT:
An apparatus for determining a characteristic of an aerated fluid flowing within a pipe is provided and includes at least one first sensing device associated with the pipe, such that the at least one first sensing device senses a low-frequency component of the aerated fluid flow and generates first sensor data responsive to the low-frequency component of the aerated fluid. At least one second sensing device is also included and is associated with the pipe such that the at least one second sensing device senses a high-frequency component of the aerated fluid flow and generates second sensor data responsive to the high-frequency component of the aerated fluid. Furthermore, a processing device is included and is communicated with the at least one first sensing device and the at least one second sensing device to receive and process the first sensor data and the second sensor data to generate fluid data.
