Document Type and Number:
Japanese Patent JP3110042
Kind Code:
B2
Abstract:
A nonintrusive flow sensing system (10) and related method are provided for monitoring fluid flow within a conduit (14), particularly such as a liquid flow (12). The sensing system (10) includes an array of ultrasonic transducers (18, 20, 24, 26) mounted on the conduit (14) and adapted to send and receive pulsed ultrasonic signals bidirectionally across the conduit with an upstream-downstream component of direction, and through the conduit in longitudinal and circumferential directions. Signal transit times are processed to obtain accurate measurements of liquid flow velocity, temperature and pressure.
