The FlowHood CFM-88L is designed for air flow measurement only.
If you need a multi-function instrument, see the pages for the ADM-850L, 860C, or 870C AirData MultiMeters.

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.

The FlowHood CFM-88L 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.
