    • The position of the displacer correlates directly with the liquid level, which is then converted into an electronic signal for level indication.
  2. Components:
    • Displacer: A weight suspended in the tank, which changes position based on the liquid level.
    • Servo Motor: Controls the movement of the displacer.
    • Measurement Transmitter: Converts the mechanical movement of the displacer into an electronic signal.
    • Level Indicator: Displays the measured level, either locally or remotely.
