Abstract
An ultrasonic flowmeter for measuring fluid flow are disclosed. The invention combines isolating conditioner technology with ultrasonic technology to determine flow velocity. The method and apparatus of the invention does not require the use of integration techniques or the prior determination of flow swirl or asymmetry to achieve accuracy. The performance of this novel flowmeter exceeds the performance of current ultrasonic flowmeters by an order of four to twelve times and offers significant savings in manufacturing and maintenance costs. The disclosed flowmeter also has self-diagnostic capabilities.
