ultego III perfect –
highest precision and reliability
Reliable Measurement
Longevity, measuring stability and a high
dynamic range distinguish the ultego III
perfect. Even after operating for years in the
district heating water environment with low
conductivity the ultego III perfect is
measuring the volume precisely and reliably.
Due to the patented DuraSurface, we are
setting new standards in measurement
stability. This future-oriented innovation
ensures measuring accuracy and
maintenance-free operation for many years.
