The invention relates to a method and device for demonstrating a concentration of a fluid ice mixture (fluid binary ice) comprising the following steps: , decoupling a partial current of the fluid which is then fed into a heat , exchanger (16) in which it is heated up to total fusion while measuring the , inlet temperature (tA) and the outlet temperature (tB); further heating the fluid current by an external source of heat and returning the partial current through the heat exchanger (16), while measuring again the inlet temperature (tC) and the outlet temperature (tD); and computing the gas concentration based on the equation Xice = (tC - tD - tB + tA) x (cpfluid / hice) where , …

Why it's free to use
- Filed August 27, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 27, 2018.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
