| Abstract: | Liquid level measuring system with the advanced fiber-optic sensing 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 by 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 0～1000mm. 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. |
