PROBLEM TO BE SOLVED: To provide a device for following the liquid level of a filling device capable of correctly elevating the position of a discharging port of a filler liquid to the liquid level without being affected by the shape of a container, presence/absence of a lid, or the property of the filler liquid when filling with the liquid in the container. SOLUTION: The device comprises a metering instrument 5 such as a load cell capable of loading a container Y for filling with a filler liquid B thereon, a computing means 6 which computes the liquid level elevating speed v from the opening sectional area A at the liquid level height h of the container Y and the specific gravity of the filler liquid B from the metered mass of the filled liquid to fill the container Y measured by the metering instrument 5 at every predetermined time, and computes the displacement speed as the displacement quantity of the liquid level height per unit time, and a control means 7 for controlling the elevating speed V of an elevating/lowering means 4 to the liquid level elevating speed v computed by the computing means 6.
