Adding to its SM range of magflow
meters, which previously had a
maximum flow rate of 100L/m,
sensor specialist ifm electronic has
introduced models with 300 and
600L/m capacities. Both are available
with a choice of seals appropriate to
different media classes, making four
new units in all.

Featuring the high levels of
accuracy associated with earlier SM
meters, the new versions offer
additional features and functions, for
example empty pipe detection to
confirm loss of the medium, and
simulation of all process variables for
test purposes. Another is the
suppression of ‘noise’ in the low-flow
range, avoiding movement resulting
from vibration or heat being
measured as flow.

All four new SM units operate on
an 18 to 32V DC supply and feature
two outputs. The outputs can switch
150mA either PNP or NPN and can
be configured for different functions.
