Introduction
The TSI®air velocity transducer is a precision instrument designed to
measure air velocity in fixed installations or test applications. TSI
Transducers indicate velocity at standard conditions of 21.1°C (70°F)
and 101.4 kPa (14.7 psia). Each transducer must be setup in the field for the
desired velocity units, full-scale velocity, output signal and time constant.

pipe the probe should be at least 7.5 duct diameters downstream and 3 duct
diameters upstream of anything that could cause flow turbulence. The
orientation dot on the probe should face upstream.
