Digital Flow Technologies Inc, spun out of technology developed in the Turbulent Shear Flows Lab at Michigan State University, is focused on the development of test equipment for the measurement and characterization of fluid flows. The firmâs longest running project is the Pulse Width Modulated Constant Temperature Anemometer, which can operate up to 18 hotwires at once while sending real-time data back to the controlling PC. More recent projects include the Thermal Transient Anemometer, which was designed to measure both the temperature and average air-flow through 32 "cells" at the downstream face of a radiator. TTA uses a multi-x array of tungsten sensor wires to measure the ambient temperature and the spatially averaged velocity in each cell. The frame that defines these cells presents minimal blockage to the airflow
