Beschreibung
Zusammenfassung:	A detection assembly for detecting moisture within an unsaturated permeable soil or soil-like medium is disclosed which includes a funnel 11 having a surface inclined in use to the vertical for distorting the flow streamlines within the medium to cause an increase in fluid content and saturation at points in the permeable medium; a cup 13 beneath the funnel for collecting free fluid from the saturated permeable medium; a sensor 14 for detecting the presence of free fluid formed upon saturation within the permeable medium, and a vent 16 for venting air from said collection means.
