Abstract : A hydraulic fluidic level sensor for detecting an angular deviation from gravity vertical comprising an inverted pendulum in conjunction with two fluidic proximity sensors to provide an output signal proportional to the angular deviation. Opposing fluid jets from the fluidic proximity sensors impinge on the inverted pendulum shaft to produce a net jet force which counter-balances the pendulum moment due to gravity. The pressure signal output from the proximity sensors is proportional to the angular deviation from the vertical and provides the input signal to a level control systems. A secondary pendulum damping system is used to provide necessary viscous damping. (Author)
