A Simplified Thermistor Flowmeter and Thermometer
L Lawn, R A Spires, T G Whitworth · Physics in Medicine and Biology · 1964
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?C to 42?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 110 mA at 10 V stabilized.
