Measurement of volume of fluid entering the cell to compensate the change in volume of the sample
The volume of fluid expelled from the pore space of the soil
The direct measurement of the change in lenth and dia of the sample.
This constant pressure system is operated with pneumatic pressure when applied through a compressed air line.Its simple to use an air water constant pressure especially where more than one outlet are to be taken from a single source.
Equipment is provided with three air water interface chambers with individual reegulators to control the outlet pressures at desired pressure levels.The interface chambers are provided with acrylic plastic chambers and two ball valves for outlet and intel of water.The chambers are fixed over a console which houses the three regulators and three pressure gauges.
