ABSTRACT:
An apparatus measures the speed of sound and/or vortical disturbances propagating in a fluid flow to determine a parameter of the flow propagating through a pipe. The apparatus includes a sensing device that includes an array of pressure sensors used to measure the acoustic and convective pressure variations in the flow to determine a desired parameter. The sensing device includes a unitary strap having a plurality of bands disposed parallel to each other. The bands are interconnected by cross members to maintain the bands a predetermined distance apart. Each of the bands having a strip of piezoelectric film material mounted along a substantial length of the bands. The piezoelectric film material provides a signal indicative of the unsteady pressures within the pipe. The sensing device includes a conductive shield around the multi-band strap and the piezoelectric film material to provide a grounding shield.
