ABSTRACT:
A flow sensor comprising a pair of thin film heat sensors and a thin film heater is disclosed. A base supports the sensors and heater out of contact with the base with the sensors disposed on opposite sides of the heater. The heater is operated at a constant temperature above ambient temperature under both flow and no-flow conditions. Also disclosed is a flow sensor wherein a portion of the depression is devoid of a side wall.
