Abstract
An air flow sensor for use with an air filter comprises a tubular housing with a flap that is opened by air pressure, the extent of opening increasing as the surrounding air filter becomes clogged. A terminal on the flap contacts different measurement terminals on the housing, closing individual circuits connected to an indicator, whereby a display shows when the filter is clear and when it is clogged.
