ABSTRACT:
A float type liquid level meter is provided having an enhanced resistance against vibration transmitted from outside of the float type liquid level meter. The inventor obtained a finding that an external vibration is amplified with a connecting lever which is composing a part of the float type liquid level meter and a fluctuation of an output signal of the float type liquid level meter is proportional to the vibration of the connecting lever. An enhanced resistance against vibration is achieved by providing a connecting lever having a structure which prevents the connecting lever from generating vibration of a low order mode.
