Open the CIPO recordAbstract From the Canadian patent
A liquid flow measuring device has a deflector (31 69) slidably mounted, relative to a cylindric inlet of the liquid to be measured for a minute, displacement along the axis of the inlet conduit. The deflector is exposed to the static pressure created by the fluid. It has a concavely shaped deflection face shaped to reverse the flow of the incoming liquid. The flowing liquid creates a dynamic force vector at the deflector in the direction of the axis thereof. The dynamic force at which the deflector is urged by and in the, direction of, the incoming flow is sensed by an electric pressure cell (42 81), whose electrical output is then directed to a suitable indicator (47) or controlapparatus. …

Why it's free to use
- Filed December 18, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 18, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 18, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
