1. A duct flow anemometer apparatus, comprising:
(a) a plurality of ultrasonic transceivers oriented towards each other in three-dimensional space, said transceivers configured to transmit and receive soundwaves along paths between transceivers; and
(b) a control processor operably coupled to the transceivers configured to activate each transceiver, detect transmitted soundwaves, measure differential times of flight (TOF) of the soundwaves of each transceiver and to determine wind velocity along each sound path;
(c) wherein said apparatus is configured to measure volumetric air flow, temperature, and both velocity and temperature distribution, within a confined directional flow within a duct; and
(d) wherein the transceivers measure averaged values of a one-directional flow within a duct cross-section that may be experiencing different velocities and temperatures at different points across the duct cross-section.
