The Drain Permeameter is suited for use both as a teaching and demonstration tool and for laboratory testing and research. A removable base section is provided into which the filter material to be investigated is placed. The equipment consists of a 100mm diameter transparent column which may be filled with any soil type.
The apparatus is supported on a sturdy metal frame and may be conveniently placed on a laboratory bench close to a water supply and drain. Water is added to the column under a constant head and permeating water and soil is collected at the base. The discharge from the drain can be monitored to assess the efficiency of the filter material.
