2. MODE/ENTER SET
Decentralised monitoring, measurement
and display of compressed air consumption.
Many sources,
including the cam-
paign ”efficient
compressed air“*
clearly indicate the
growing interest
in the optimised
use of the energy
carrier compressed
air. This is a sub-
stantial saving
potential for
operating costs.
efector metris
helps to explore
this potential.

The integral
4-digit LED display
plus the status

mation to be avail-
able at the point
of monitoring.

pushbutton.
All settings can be
protected using

The installation
of several measur-
ing points in the
compressed air
system clearly
shows where and
how much com-
pressed air is con-
sumed. Thus the
consumption can
be allocated to
production
processes or prod-
ucts for optimising
cost structure.
Decentralised
location of efector
metris in the sup-
ply pipe to the
individual
machine unit.
Location of
efector metris in
the supply pipe
prior to distribu-
tion to several
installations or
machine units.
Leakage monitoring
Two reliable indications of air leakage
are the increase in consumption of com-
pressed air with unchanged machine
load and the continuing consumption
of compressed air when the machine is
no longer in operation.
Leakage at a glance.
The compressed air meter´s integrated
pipe length ensures easy mounting
and high measurement accuracy.
Easy to mount
in the supply system.

4. MODE/ENTER SET
From now on: Accurate monitor-
ing of compressed air consump-
tion with efector metris.
The low purchase price makes it
possible: To measure compressed
air where it is used.
Even very small leaks are detect-
ed and can be repaired in good
time.
The quantities consumed can be
directly allocated to the relevant
production units.
In situ display of total or current
consumption.
Switching, pulse or analogue
outputs for further external
processing.
Determine maintenance intervals
depending on consumption.
Measurement free from pressure
loss due to a special design of
the measuring probes.
Response time in the millisecond
range.
Calorimetric
measuring principle
Integrated
display for
direct
indication of
consumption.
Even small leaks
can cause unneces-
sary electricity
costs of several
thousand Euro
per year.
The calorimetric
principle measures
the standard
volume flow
irrespective of
temperature and
pressure – quickly
and over a wide
measuring range.
Leakage detection, energy cost
reduction and environmental protection.
