SCS 9023

Flow resistance

Flow resistance parameter of porous materials is determined using a device where a cylindrical chamber is closed with the material sample and a piston system is pumping air inside the chamber. A pressure microphone is measuring the pressure level inside, from which the flow resistance value is calculated.
The porous samples have the same dimension as the ones for the Kundt device large tube (low frequency).

The delivered system includes all mechanical and electrical parts and the microphone system with preamplifier, cable and microphone supply.

The Flow Resistance device ensemble for the SCS 902A system is available as a separated set which can also be connected with other acquisition and analysis system.
