本文简述了LS25-1型流速仪主要结构元件的特性、高速检定经验及不同旋桨的高速性能,指出,虽然该型仪器能用常规检定公式外延至10m/s使用,但只能是以往一种应急措施。施测高速应采用专用的高速流速仪LS20B型或LS25-3型。
This article briefly describes the characteristics of the main structural components of LS25-1 type flow meter, high-speed verification experience and high speed performance of different propellers. It is pointed out that although this type of instrument can be extended to 10m / s using the conventional verification formula, A kind of emergency measure. High-speed testing should be used dedicated high-speed flow meter LS20B type or LS25-3 type.
