Performance Evaluation of a Fluid Temperature-Compensated Single Sensor Constant Temperature Anemometer.

The performance of a hot-wire anemometer configuration is affected by variation in the fluid temperature The classical temperature compensation techniques in such anemometers employ two sensors. The performance of a temperature-compensated hot-wire anemometer configuration using a single sensor alternating between two Operating temperature and proposed for constant fluid velocity is investigated under conditions of time-varying fluid velocity. The measurement error introduced is quantified and can be practically eliminated using low-pass digital filter. [ABSTRACT FROM AUTHOR]
