摘要
本文介绍了研制的新型三相脉冲电导式空隙率计.与国外代表性的Merilo旋转电场式空隙率计比较,其传感器结构和激励电源等均有新的创新.研究结果表明:仪表在线性度、测量精度、频率响应以及结构简化等方面,均有提高和改进.
A new three phase impulse inductance void fractionmeter for the measurement of void fraction in gas-liquid flow is presented in this paper. The new meter is realized through the modification of the conventional one developed by Merilo. Circular electrodes instead of strip ones, and a stimulating power supply with impulse output instead of sinusoidal wave output are used. Experimental results show that, compared with those of the conventional one, the linearity, accuracy and frequency response are improved and the circuitry is simplified.
