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.
