  • Monitor apparatus for a bed underlying water
    Patent number: 5349327
    Abstract: A sensor is located in a bed underlying water. A downward array of sensors may be buried in the bed during normal flow conditions so as to be in a disabled mode. The sensor has an oscillatable arm (21) having a first end portion (22) for supporting the arm, and a second end portion (23) housing a sensor cell (25) e.g. an omni-directional mercury switch. The alarm signal may be indicative of risk of collapse of a hydraulic structure, e.g. the foundation of a bridge pier.
