Micro Flow Permeameter
The PMI Microflow Porometer is a Capillary Flow Porometer with the ability to measure pore structure and permeability in nearly impermeable materials. This instrument is user-friendly and fully automated. The Microflow Porometer is an asset in quality control and R&D environments.
Feature
- Samples permitting very low flow rate can be tested
- Very low permeability can be measured
- Fully Automated
- Windows based simple operation Optional :
- Sample under compressive stress
- Elevated temperature test
- Determination of In-Plane Structure
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.
- Where F is flow rate at standard temperatute, T , and standard pressure, P , V is the volume of the down stream side of the sample chamber, T is test temperature, t is time, and P is test pressure. Flow rate through dry sample is measured with increasing differential pressure.
