Abstract
An apparatus for measuring at least one parameter associated with a fluid flowing within a pipe includes a single sheet of piezoelectric film material wrapped around at least a portion of the pipe and an array of sensors disposed at different locations on the film material. Each of the sensors provides a signal indicative of pressure within the pipe at a corresponding axial and/or circumferential location of the pipe. The sensors are selectively configurable to provide the pressure signals. The signals are processed to determine the parameter. The array of sensors is configurable in response to different criteria. The criteria includes at least one of the parameter of the fluid to be output, an input signal specifying sensors to be selected, a predetermined configuration based on the parameter to be determined, and in response to a previously determined parameter of the fluid.
