Is there very good and precise way measure air flow by way of a ductless head, for the objective of diagnostics (say, to compute the warmth output)? The ACEEE Pacific Northwest review made use of a small vane anemometer in a few fashion, but no point out of an equipment to constrain geometry to the known quantity (much like the cross-sectional spot of the flow hood), and I couldn't find any certain feedback on the accuracy or %mistake of their measurements.
