Abstract: A level indicating device for liquid filled containers is provided having a floating sensing element which is operatively connected with a signal device, the sensing element having several, preferably three floats arranged on a single plane. The floats are supported on lever arms which are interconnected with each other at a central union. The lever arm union is supported for free movement in a guide disposed approximately in the center of the container and approximately vertically aligned with the surface of the liquid when the liquid is at rest. The longitudinal movement of the lever arm union in the guide caused by changing liquid levels is transmitted to a signal device for monitoring the liquid level.
