Abstract: An on-line pressure measuring system for annular gap of
membrane separator is developed, with the aid of computer. This system
has high precision by using advanced software developing tools, such as
Delphi and Access 2000. It can detect the annular gap pressure and the
permeating flux in the rotary crass-flow membrane separator fairly
accurately and reliably, also can be applied to the measurement of
pressure and flux for other kinds of membrane separators, and provides
the effective means for further research on enhancement mechanism in
membrane micro-filtration.
Key words: Membrane separating On-line Pressure measurement
