L-shaped Pitot tube measurement allows reliable
measurement in ducts where the air may be
polluted, at high temperature, slightly turbulent,
and up to a speed of 100 m/s. This measurement
is done using the pressure sensor integrated into
a pressure gauge or into a multifunction device.

To compensate for possible turbulence, our
Classe 210 and 310 devices have a
“measurement integration” function which
smooths out fluctuations. An averaging function
also makes it possible to reliably determine the
speed or flow rate in the duct.

Sauermann manufactures DEBIMO wings with
different measurement sockets positioned
according to the NF X10-112 standard ensuring an
effective average. This measurement can be
compensated for temperature and atmospheric
pressure depending on the associated sensor
model.

For very sensitive and precise measurements on
non-turbulent flows up to 50°C, the hot wire is
recommended. In flows that can be turbulent and
polluted up to 210°C, DEBIMO wings provide a
more suitable averaged multipoint measurement.

Our technicians calibrate on-site the temperature
probes and pressure sensors associated with
DEBIMO wings or Pitot tubes.

Direct speed and flow calibrations are carried out
on our laboratories' large test benches, which
offer state-of-the-art calibration certainty.
