A Compensation Method for Solid Concentration through Measurement of Water Content with Capacitance Sensors in Gas-Solid Flow

摘要

The moisture content has great effect on capacitance transducer for measuring concentration of two-phase flow of solid/gas. The paper describes an method of correction the error caused by moisture content in capacitance transducer by designing feedback parameters specially. The experimental results showed when variation of moisture content between 0.5%-2% . The measurement error of the concentration of two-phase flow of solid-gas could be restrain below 5% .
