Measuring with falling head technique
Fill burette with up to 5 cm (2 in)
water column.
Start measuring mode „Falling Head“
in the software.
Open burette cock quickly.
Note: How long measuring with falling head and constant head takes
The ballpark duration is seconds to a few minutes for very conductive substrates
like sand (~1000 cm/d or 400 in/d), whereas measuring substrates like unstructured clay
with very low conductivity (< 0,1 cm/d or 0,05 in/d) may take about 24 hrs or longer.
