摘　　要：采用先进的光纤传感技术在人工浮子液位计的基础上研制了一种新型的液位测量系统。系统利用力平衡原理测量液位，利用光纤传感器探测和传输信号，采用自制的光学编码盘实现光信号的调节。测试结果表明，在0～1000mm测量范围内，测量误差≤±6mm，相对误差〈2％。现场应用表明，该系统的各项性能指标符合生产要求，运行稳定，性能可靠。Liquid level measuring system with the advanced fiber-optic serasing technology based on the traditional floater level meter is developed. It measures the liquid level of an oil tank by using the principle of force balance, captures and transmits optical signals hy means of the fiber-optic sensors, implements optical signal modulation with the self-made light code disc. The testing results indicate that the measurement error is≤±6mm, relative error is〈 2%, when its measuring range is 0 1000rnm. By applying in a chemical plant, it is proved that every specification of the system meets the demands of its users and its performance is reliable.
