2.9 Micrologger
Options
The Micrologger is a factory fitted option that mounts within the water level
instrument housing. When you use a Micrologger you do not require an external
data logger to store water level measurements over time. The Micrologger has most
of the features of a UNIDATA STARLOGGER and is operated in the same way
using the same software as all other UNIDATA loggers.
The 6541B-nn-C instrument incorporates the UNIDATA 6541L Micrologger. See
Appendix A for details.
Water level is measured using the Micrologger’s high speed serial IO channel. The
Micrologger has two analogue inputs and two digital and inputs. Its also has a
counter input. You can use these inputs to measure other physical parameters such
as rainfall, water or air temperature, barometric pressure and wind direction.
The 6541L Micrologger also includes one open collector output that can control an
external device.
You should use the 6541-nn-C when you need to measure water level and a couple
of other physical parameters.
The 6541B-L Micrologger is program-compatible with UNIDATA data loggers.
