  • Fluid flow direction and velocity monitor and temperature compensating circuit therefor
    Patent number: 5522261
    Abstract: A fluid flow direction and velocity monitor, particularly useful in monitoring pressure differentials between a controlled environment and its surroundings, includes a heated thermal sensor situated between upstream and downstream cold thermal sensors within a channel. The heated thermal sensor provides a pressure differential or fluid flow velocity signal. The pair of cold thermal sensors are utilized to provide both temperature compensation and fluid flow direction. The pressure differential and direction signals are combined by the circuitry to yield a single digital direction and pressure signal.
