The LR level sensor is suitable for contin-
uous level monitoring. It measures level
using the guided wave radar principle.
The LMT point level sensor switches in
contact with the medium, e.g. to monitor
minimum or maximum levels. The sensor
can also be used for run-dry monitoring
of pumps. The optimum adjustment to
the medium is done via IO-Link. If there
are different media, the parameters can
also be changed via IO-Link.

The compressed air meter efector metris
(SD series) measures the consumption of
compressed air or technical gases and the
temperature of the medium. Compressed
air is one of the most expensive energy
carriers in production. Therefore monitor-

in large installations or for large machines.
