ABSTRACT:
A hot wire flow rate measuring apparatus, having a platinum wire sensor and a thermistor in the upper limbs of a bridge circuit whose lower limbs have resistors. The thermistor, together with a linearising resistor and a scaling resistor, is connected into the bridge circuit via a potential divider. A differential amplifier and a transistor control the supply of power to the bridge circuit so that the platinum wire sensor is maintained at a higher temperature than the thermistor by a fixed temperature difference.
