17. D6 rotating vanes FVAD15H
The ALMEMO
®
D6 sensor FVAD 15-H serves for measuring unidirectional and bidi-
rectional flow velocities in gases and liquids. You can either select the medium and
enter the density via the sensor menu on the V7 device or directly on the PC by means
of the adapter cable ZA 1919 AKUV.
The design is extremely compact and is particularly suitable for mobile measurements
in air-conditioning and ventilation applications. The probe head has an aero-dynami-
cally optimized shape and protected bearings.
The high-resolution acquisition of the frequency signal and the directional detection of
the flow take place in the ALMEMO
®
D6 plug. When leaving our factory, the ALME-
MO
®
plug is preprogrammed with one measuring channel (flow in m/s). In addition,
further measuring channels are available and can be selected via the sensor menu.
17.1 Measuring ranges upon delivery
The measuring range for the flow velocity will be configured in accordance with the
connected rotating vane (probe heads: mc/mn/md with the ranges 20/40/80/120 m/s).

17.2 Configuration on the PC via the sensor menu
Depending on the type of rotating vane, initially only 1 measuring range is program-
med (* factory default setting). If needed, this range can be changed, and on the 4
measuring channels additional ranges such as frequency or revolutions per minute can
be configured (see table below).
