摘　　要：光纤光栅传感技术具有光纤传感技术的所有优点,内锥式流量传感器具有量程比大,压损较小,耐高温高压,要求前后直管段长度小的特点。将光纤光栅和内锥流量传感器结合组成了新型的光纤光栅内锥式流量计,介绍了光纤光栅和内锥式流量传感器的工作原理,光纤光栅内锥式流量计的组成,实验数据和结论。Fiber optic grating sensors possess all the advantages of fiber sensing technologies. V-cone flowmeter presents the characteristics of great turndown ratio, lower pressure loss, resistance to high temperature and high pressure and little requirement of the length of straight pipe up-and-down stream. By combining fiber optic grating and V-cone flowmeter, a new fiber optic grating based V-cone flowmeter is accomplished. In this paper, theories of fiber optic grating and V-cone flowmeter, composition of fiber optic grating based V-cone flowmeter, experimental data and conclusion are presented.
