摘要
火电厂中煤位和粉位的正确测量对机组的优化经济运行具有十分重要的意义。利用射频导纳原理解决导电介质物位测量中的挂料问题,准确测得π/4相位点的信号幅值,则能较好地消除挂料引起的误差。
The exact measurement of material level gauging in thermal power plant has a great economical meaning to optimize the running of units. Theory of RF admittance is used to solve the problem of Probe Attachment in material level gauging. The error from Probe Attachment is well eliminated by the excatly measuring signal from π/4 phase point.
