3. About the instrument
With this air speed meter (or anemometer) you have acquired a preci-
sion instrument of exceptional quality. You also obtain the benefit of
our many years' experience in measuring physical data on running
paper machine clothing.
All probes have been calibrated in a wind tunnel and are checked to
conform to the required tolerances.

The instrument is built up out of an electronic
read out unit, a probe with a small propeller that
is installed in a plastic measuring head and a
telescopic grip.
• The air flow is measured by a small, aerody-
namically optimised propeller which is extre-
mely accurate and reliable.
• The plastic measuring head is made from
HDPE which ensures low friction with the felt.
Contamination will not stick to the material,
therefore it can be cleaned easily.
Average, minimum and maximum values can be
called up at any time. As the calculation of
these values takes place simultaneously they
can be requested at any time, the test result is
not affected.
