摘要： The oscillation frequency of the output signal of a ring oscillator is changed in response to a change in the relative position between the coil in the ring oscillator and a float including a conductive member and vertically movable in accordance with changes in the level of a liquid to be measured. The amount of electric power consumed by the ring oscillator itself is changed in accordance with changes in the oscillation frequency of the oscillator output signal. The power consumption of the ring oscillator is detected in accordance with the voltage across a resistor inserted in the power line from the electric power source to the ring oscillator, so that when this voltage attains a predetermined value, an indicator designed to indicate that the liquid level has attained a predetermined level is brought into operation.
