The instrument comprises of a mechanical guage that works with a float to accurately measure the level of liquid in a tank. The liquid level is transmitted by means of a tape connected to float on one side and gear mechanism on the other side. The gears rotate the pointer on a dial or counter mechanism to display readings.

A drum and spring mechanism provides constant tension on tape to keep it straight and thus balancing the force due to apparent float weight on one side and spring tension on other side.
