SATURO
3. SYSTEM
This section describes the specifications, components, and theory of the SATURO system.
3.1 SPECIFICATIONS
MEASUREMENT SPECIFICATIONS
Range 0.0038–115.0000 cm/h
Resolution 0.0038 cm/h
Accuracy ±5% of reading
The
fs
values that can be effectively measured by SATURO are limited by the
listed minimum and maximum infiltration rates. These depend on the pressure
heads applied to the water during infiltration and to the three-dimensional flow
characteristics of the soil, so the measurement range of K
fs
cannot be specified
explicitly. SATURO will generally be able to make measurements on poorly to
moderately structured soils as coarse as medium sand, but the maximum infiltration
rate can be exceeded by soils with excessive structure and especially by soils with
0–40 cm (vacuum is applied for <5 cm settings)
