摘要：
This paper presents an example where an off-line experimental technique based upon idealized how test models is applied as an alternative method of evaluating a commercial solids flow instrument in a well-controlled environment. The systematic characteristics of a 150 mm bore commercial capacitance transducer were quantified as applied to the volumetric concentration measurement of particulate solids. Results obtained from the experimental studies are presented in terms of overall sensitivity, linearity, sensing field homogeneity, material dependence, moisture and temperature effects.
