Abstract (en)

[origin: DE19737983A1] 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 cpfluid is the heat capacity and hice is the fusion enthalpy of the binary ice.
