PPD is used to measure the permeability of soils and filter media. Constant head and falling head tests are run on a packed column while head and flow are recorded, giving the coefficient of permeability of the sample.

PEIF is used to determine the filterability index of a suspension. The sample is filtered under controlled pressure while the volume of filtrate is recorded against time, giving the specific resistance of the cake. A computer controlled version, PEIFC, is also published.
PL is a lysimeter for measuring the water balance of a soil block. Rainfall or irrigation input, drainage output and the change in stored water are recorded so evapotranspiration can be calculated over a period.
PEFP is used to study flow through packed and fluidised beds. Water or air passes upward through a granular bed while pressure drop and flow are measured, giving the permeability and the minimum fluidisation velocity. A computer controlled version, PEFPC, is also published.
