Electronic FlowHood
DIRECT DIGITAL READOUT,
SUPPLY OR EXHAUST, ENGLISH AND METRIC
 The FlowHood
CFM-88 is used for air flow measurement only, and comes complete
with a CFM-88 meter and an air capture hood kit. The FlowHood
Model CFM-850 has added functions for pitot tube air velocity,
differential pressure and temperature measurement. FlowHood kits
may be ordered with any combination of top sizes. Special top
sizes will be designed to order upon request.
DIGITAL
READOUT
The FlowHood CFM-88 uses the electronic, digital AirData Flowmeter
for direct readout at supply, return, or exhaust outlets, in
cfm or litres/sec. This rugged, shock resistant meter automatically
selects the proper range and corrects for local air density.
These features eliminate several error factors and the calculations
necessary to convert air flow readings to true local density
results. Internal calibration and zeroing are full automatic.
No adjustments are ever needed.
BACKPRESSURE
COMPENSATED
The air delivery of an air outlet or inlet is always reduced
to some degree when a capture hood is in place. The flow reduction
depends on the ratio of the outlet resistance to the FlowHood
resistance. This "backpressure" caused flow reduction
is unpredictable from one outlet or damper setting to another.
The electronic FlowHood combines an innovative design concept
with state of the art microprocessor technology to calculate
the backpressure effect of the FlowHood. The displayed reading
indicates the true air flow through the outlet that exists when
the FlowHood is not in place.
Capture
hood kits are available without a meter and are designed for
use with any model of the AIRDATA MultiMeters. The kits include:
flow measuring base with sensing manifold; two position flaps
and control; pushbutton handle; various standard and special
top sizes; and carrying case. Choice of meters - air flow only,
or air flow, velocity, pressure and temperature. Options include:
memory, average and sum to 100 readings, sequential recall, auto-read,
VelGrid, Air Foil and TemProbe. Repair policy - ten day turnaround
or less - all models in stock.
