Abstract:
A flow measurement system for determining the velocity of a fluid flow, comprising:a hollow tubular member opening at a first end and a second end, said first end adapted to the fluid flow traveling longitudinally through said tubular member and said second end adapted to discharge the fluid flow traveling longitudinally through said tubular member;a first annular ring transducer disposed in said tubular member, said first annular ring transducer having a first angled ring transducer, said first angled ring transducer having a first slanted outer face and a first slanted inner face opposite said first slanted outer face, said first angled ring transducer being poled at an angle to said fluid flow;a second annular ring transducer disposed in said tubular member in a spaced-apart relationship with said first annular ring transducer, said second annular ring transducer having a second angled ring transducer, said second angled ring transducer having a second slanted outer face and a second slanted inner face opposite said second slanted outer face, said second angled ring transducer being poled at said angle to said fluid flow; andsaid first annular ring transducer and said second annular ring transducer positioned such that said first slanted inner face is facing said second slanted inner face.
