| Abstract: | The pressures of probe holes react slow when measuring flow field because tube diameter is very small, which affects measuring precision and rate of progress.This paper advanced the methods computing the pressure reacting times of probe systems with given measuring precision. Reacting properties of 3 types of probe systems measuring water flow field were compaired with those measuring air flow field. The factors were analysized that influence the pressure reacting time. The reasonable systems and system parameters were presented in order to improve measuring precision and shorten testing time. |
