Achieve More Productivity with OPTIMASS - Krohne

The Adaptive Sensor Technology of
Optimass removes the problem of external
influences affecting measurement by using its
own internal mass as a self compensating
mechanism therefore responding quickly to
changes in density.
Application Story
Salt Mining in Austria
Shortly before its 25th Anniversary, Saline Austria in Ebensee
modernised its installation in order to optimise production
processes and minimise environmental impact.
The brine tanks accumulate a slurry of chalk and
gypsum at the bottom which has to be drawn off
periodically. This led to a lot of the brine also
being lost. However with the use of Optimass
meters to measure the density, the valves can be
closed as soon as pure brine is measured. The
slurry density is around 1.3 kg/l and drops to 1.15
with pure brine.
Additionally a KROHNE Optimass is helping to improve the environmental impact as
the waste water slurry from the process is no longer discharged into the Traunsee Lake
but pumped back from Ebensee via a 20 km pipeline where it is forced into the salt
caves of Bad Ischl which in turn displaces new brine. This is then returned by a
separate pipeline. Here also, the KROHNE meter is being used for density control.
Application: Salt production
