Description:	Accurate and reliable measurements of field-saturated hydraulic conductivity (Kfs) are essential for accurate determinations of soil and solution water fluxes. Kfs is a crucial parameter to design drainage, irrigation systems and many other environmental, agricultural and industrial installations. A popular device to measure the Kfs is the head well permeameter such as the Guelph Permeameter. However, it is an analog equipment based on a Mariottes bottle that is manually operated, where the reading of the flux values (Q, in cm3/min) is time-consuming and costly. We develop a device, with a digital readout, to measure the steady state rate of water level change Rs, in order to Kfs.
