A Simplified Thermistor Flowmeter and Thermometer

Abstract
A thermistor unit has been designed to give a continuous record of changes in flow rate from 2 ml/min to 40 ml/min and temperature measurements from 32[degree]C to 42[degree]C. A meter is provided for visual readings and switched terminals for leads to a graphic recorder. The stability and response times are good and it has been found unnecessary to recalibrate before each experiment, The power requirements are 110mA at 10 V stabilized.
