Abstract
Automated measurement of fluid solution capacitance in industrial processes to determine solution concentration. Industrial process control transmitters determine solution concentration directly from solution capacitance and confirm concentration determinations based on solution conductivity. The industrial process control transmitters include terminals embodied in wire coils and/or metallic plates, at least one processor, and at least one computer readable memory device.
