Temperature signal decoupling of heat transfer probe for gas-solids flow measurement

摘要

A new decouple method of the heat transfer probe for measuring the gas-solid two-phase mass flow is presented. The gas-solid two-phase mass flow can be measured on-line by a heat transfer probe, and the temperature of the fluid is useful for the data fusion to get high accuracy. the measure range of the temperature was expanded by the new circuit and higher accuracy achieved. Experiments are carried out in a specially designed laboratory scale pneumatic conveyor and the result shows that this method can perform compound measurement.
