A method and apparatus for determining at least one characteristic of a
fluid flowing within a pipe is provided and includes at least one sensing
device. The at least one sensing device includes a first sensor segment
having a first segment polarity and being associated with a first outer
portion of the pipe and a second sensor segment having a second segment
polarity and being associated with a second outer portion of the pipe,
wherein the first sensor segment and the second sensor segment generate
sensor data responsive to the fluid flowing within the pipe. The
apparatus further includes a processing device communicated with the at
least one sensing device, wherein the processing device receives the
sensor data and processes the sensor data to determine the at least one
characteristic of the fluid.
