Open the CIPO recordAbstract From the Canadian patent
A nonintrusive flow sensing system and related method are provided for monitoring fluid flow within a conduit, particularly such as a liquid flow. The sensing system includes an array of ultrasonic transducers mounted on the conduit 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.

Why it's free to use
- Filed August 14, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 14, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 14, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
