Paper Abstract

A new technology that uses a single sensor for temperature and velocity measurements in nonisothermal fluids is presented in this paper. The system is a multi-channel scanner designed for measuring velocity and temperature in applications where single- or multi-point measurements are required. This unit uses 12-bit data acquisition system along with digital circuitry for measuring both velocity and temperature with the same sensor. These unique sensor are designed to be low profile to minimize flow disturbance. Of the salient points of the new system is elimination of measurement error as seen in dual sensor system used in the same application. Dual sensor induced errors can be in excess of 20 percent that are caused when these sensors are used in non-isothermal flows. This technology provides an accurate and easy to use vehicle for mapping the temperature and velocity of flows in multitude of environments.
