  • Overload protected pressure transducer
    Patent number: 4543832
    Abstract: A liquid filled pressure transducer which utilizes a self activating lip seal type valve to create a sealed cavity within the transducer to prevent the flow of liquid from behind the pressure diaphragm and thereby prevent distortion of the diaphragm under overload conditions. A mechanical stop prevents excess displacement of the sensor element.

  • Apparatus for the ultrasonic measurement of the flow velocity of fluent media
    Patent number: 4203322
    Abstract: In an ultrasonic flowmeter ultrasonic signals are transmitted alternately upstream and downstream of a fluent media whose flow velocity is to be ascertained. The repetition rate at which signals are transmitted is controlled by a voltage controlled oscillator. To increase the sensitivity of the meter, the frequency of the voltage controlled oscillator, which is related to sound speed through the fluent media, is increased.
