The performance of existing variometers is first considered in relation to the size and shape of typical thermals, the performance of a modern glider and the reaction time of the pilot. The need for an electric instrument is shown. Two basically different ways of using thermistor beads to measure speed and direction of airflow from a flask are considered...Simple arrangements for checking the performance of a variometer on a test bench and in a car are described in detail....
