Abstract
A flow sensing or differential pressure sensing device utilizing a pair of bridges is disclosed. A first bridge operates a heating element and a temperature dependent resistor to in turn control an error integrator. The error feedback provides the voltage for both of the bridges thereby keeping the operation of the bridges compensated for ambient temperature variations.
