Study on pressure measurement system for the annular gap of membrane separator with rotary cross-flow

An on-line pressure measuring system for annular gap of membrane separator is developed with computer. This system has high precision because of the 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 accurately and reliably, and can also be applied to the measurement of pressure and flux for other kinds of membrane separators, which provides effective means for the further research of enhancement mechanism in membrane micro-filtration.
