ABSTRACT:
A hot wire flow apparatus for generating a flow rate signal indicative of the actual flow rate of a pulsating fluid flow. The apparatus utilizes a wire element connected with a temperature compensating circuit to generate a flow rate signal indicative of the pulsating fluid flow, but lower in value than the equivalent steady state flow rate. A correction circuit is provided to receive the flow rate signal and generate a corrected flow rate signal indicative of the actual flow rate of the pulsating fluid.
