Abstract
Aiming at requirements about debris ferromagnetism distinguishing
debris separating sensor and vision measuring system are designed.Force on the debris in the flow field and magnetic field is analyzed
and indirect method of measuring ferromagnetic debris based on the measuring information of total flow pipe and non-ferromagnetic debris flow pipe is suggested.DPIV method is applied to measure the flow field on observe pots and solve the problem of exactly calculating contamination degree.At last the measuring performance of the system is validated.
