Systems for determining a volumetric ratio of a material to the total materials in a mixing vessel
First Claim
1. A system for estimating a volumetric ratio of a material to total materials in a mixing vessel, comprising:
- a summation block for determining an estimated volumetric rate of change of the material in the mixing vessel;
an integration element for determining an estimated volume of the material in the mixing vessel based on the estimated volumetric rate of change of the material in the mixing vessel;
a first gain element for converting the estimated volume of the material in the mixing vessel to the estimated volumetric ratio of the material to the total materials; and
a second gain element for converting the estimated volumetric ratio of the material to the total materials to an output flowrate of the material from the mixing vessel.
