摘　　要：在分析光纤光栅靶式流量传感器的基础上,采用并联匹配光栅法对波长进行了解调,并基于虚拟仪器(LabVIEW)实现了对流体的测量。这种处理方案不但解决了传统单匹配解调技术中的双值和可测试范围小的问题,而且提高了测试准确度。实验结果表明,该流量测量系统稳定可靠。Analysis the FBG target type flow sensor, achieved the wavelength demodulation used the parallel match demodulation method and a flow measurement system based on LabVIEW is presented. It solves inherent problems of the traditional one： double-values and small measurable range, and enhances the precision. The experimental results indicate, the flow measurement system is stable and reliable.
