Introduction

Operation Principle
In this instrument a pressure transducer is located on the downstream side of the sample and the time rate of pressure change in the known volume of the down stream side of the sample chamber is used to compute very small flow rates. The flow rate through dry samples is measured according to the differential pressure. Under the increasing pressure, the gas flows into the back of the completely wetted samples in the chamber. When the pressure increases enough to overcome the point where the capillary of the liquid works in the hole (maximum hole) , that point is the bubbling point. After confirming the bubbling point, increase the pressure and measure the flow until all the holes are empty and the sample is dry.

Features
· Samples permitting very low flow rate can be tested
· Very low permeability can be measured
· Fully Automated
· Windows based simple operation
· Provide other optional features
