摘要
针对纸浆液固两相流质量流量和浓度测量过程中存在的问题,研究开发了一种复合式质量流量计。该流量计一方面采用DSP和频域相关算法实时、高精度地获取体积流量信号;另一方面采用静刀式浓度变送器获取浓度信号,并通过C8051F005单片机间接得到纸浆质量流量。试验表明,该流量计能够同时输出体积流量、浓度和质量流量信号,在纸浆两相流测量领域具有良好的应用前景。
Aiming at the problems of the mass flow and concentration of pulp liquid-solid two-phase flow measuring~ a compound mass flow meter is researched and developed. One side, DSP and correlation algorithm of frequency domain are adopted to obtain the volumetric flow signals accurately in real time; on the other hand, the static blade consistency transmitter is used to get the concentration signals, and pulp mass flow is calculated indireedy by C8051F005 MCU. The experimental results show that this flow meter is powerful in functions of outputting volumetric flow, concentration, and mass flow signals simultaneously and features good prospect in the field of measurement for pulp two-phase flow.
