Control of flow ratio (control of chemical or physico-chemical variables, e.g. pH-value, G05D21/00; control of humidity G05D22/00; control of temperature by varying the mixing ratio of two fluids having different temperatures G05D23/13; control of viscosity G05D24/00) > Controlling ratio of two or more flows of fluid or fluent material > with auxiliary non-electric power > by sensing concentration of mixture, e.g. measuring pH value
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
