  • Valve monitor and method
    Patent number: 4821769
    Abstract: A method and apparatus for monitoring operation of a valve is disclosed in which a signal, such as an alternating current electrical signal, is propagated through a fluid path defined by the valve. The occlusion of the fluid path is indicated by monitoring the propagation of the signal. The system is highly immune to electrical noise and to variations in fluid conductivity. The system is also well adapted for monitoring operation of valves having a plurality of ports. In installations employing a plurality of valves, as plurality of valve monitors can be used without mutual interference.
