Fundamental Science on Nuclear Safety and Simulation Technology Laboratory, Harbin Engineering University, 145Nantong Street, Harbin 150001, China  (gaopuzhen@sina.com)   Abstract: In this paper, single-phase experiments were conducted in different sinusoidal flow condition for studying the dynamic response of measurement sensors. The obtained experimental data were fitted as the form of transfer function between flow rate signal as Input and pressure drop along the channel as Output of the dynamical system and to give the transfer function model of the second order model. By the derived transfer functions it becomes possible to trace the actual flow condition in the channel, by which it becomes possible to measure magnitude deviation and the phase difference caused by the sensors’ natural dynamic response delay. Keyword: sensor delay, phase difference, magnitude deviation, sinusoidal change of channel flow
