  • Fluid flow direction and velocity monitor
    Patent number: 5461910
    Abstract: A fluid flow detection monitor (80), particularly useful in monitoring pressure differentials between a controlled environment and its surroundings, includes a heat source (1) situated between an upstream and downstream thermal sensor (2,3) within a channel (5). The electrical resistance of the downstream sensor varies as the downstream sensor is heated from fluid carried past the heat source. Circuitry is used to detect the electrical resistance differential between the thermal sensors, thereby detecting the presence of fluid flow.
