2. Volumetric flow sensor efector mid. High-precision
measurement, display and signalling of liquid media.
For industrial
applications
Coolant monitoring Cooling water monitoring
Ideal in widely
branched cooling
systems, e.g. weld-
ing lines. The
volumetric flow
sensor efector mid
detects very small
deviations from
the specified volu-
metric flow quan-
tity, for example
for leaks, and
monitors at the
same time the
temperature of
the cooling water.
This guarantees
process safety and
quality.
Decentralised
detection and
monitoring of
liquid media.
The diagnostic
functionality of
efector mid, e.g.
analogue outputs,
binary limit values,
consumed quanti-
ties during the
specified period or
temperature mon-
itoring in the
medium, enables
the reliable opera-
tion of cooling cir-
cuits and systems.
Due to the contin-
uous monitoring
the sensor can be
perfectly integrat-
ed into the condi-

tion-based main-
tenance concepts.
This enhances the
reliability of the
plant; uptime is
increased. Expen-
sive consequential
damage resulting
from lack of cool-
ant is prevented.
By integration into
a real-time-main-
tenance concept
maintenance can
be implemented
at the right time,
in the right place,
using the right
material and oper-
ators.
The magnetic-
inductive volumet-
ric flow sensor is

tivity. efector mid

3. Measuring length
and electronics are
integrated into a
robust and com-
pact housing. So
otherwise usual
inlet and outlet
pipe lengths can
be reduced to a
minimum. Pressure
loss is negligible.
Compact, informative
and easy to install.

the unit of mea-
surement. Two
LEDs indicate the
switch points.
Mounting via
R 1/2 or R 3/4
adapter ensures
easy installation in
the pipe.

efector mid – the
reliable and low-

liquids in industri-
al processes. Due
to the measuring
range of 0 to
25 l/min and an
accuracy of ± 2 %
of the measured
value the unit can
be used in a wide
range of applica-
tions. Volumetric

logue outputs for signal
and control tasks.
Less cost:
Setting and monitoring of
cooling circuits for optimum
performance.
More safety:
Immediate detection of
even very small leaks.
High transparency:
Counting and allocation of
consumed quantities.
Exactly right:

converted in the
evaluation electro-
nics. As the pipe
cross-section is
defined, the
volumetric flow
quantity can be
determined
exactly.
No moving com-
ponents are used,
therefore the
system works relia-
bly, wear and
maintenance free.
The volumetric
flow sensor is
based on Faraday’s
principle of induc-
tion. The conduc-
tive medium
flowing through a
pipe in a magnetic
field generates a
voltage which is
proportional to
the flow velocity
or volumetric flow
quantity. This vol-
tage is tapped via
electrodes and
