FEATURES
❏ Compact sensors
The thin sensors with thickness of only 10mm can be
installed at a tight space such as between a radiator and
condenser.
❏ Accurate directional measurement
The vane wheel of the meter, its axis aligned parallel to the
air flow direction, allows accurate measurement of the flow
along the perpendicular to the radiator, neglecting the flow
from the other directions. On the other hand, other types of
sensor such as thermal type or pressure type tend to
measure flow from all other directions.
❏ Low pressure loss
The pressure loss across the vane wheel is about 0.1kPa at
the velocity of 20m/s. This value is very low compared to the
pressure loss across the radiator itself.
❏ Resistant to measuring noise
The optical sensing system, by detecting optically the
number of rotations of the vane wheel, is not influenced by
the electromagnetic noises.
❏ Reverse flow measurement
Not only the air flow from the front of the vane wheel but the
air flow from the back can be measured.
❏ Communication function
The RS232 converter can collect 64 channel data with
RS-232C communication protocol.
