displacement-type float

A device for measuring the liquid level in sumps or vessels. It consists of a float, whose vertical height is greater than the level range being measured and whose weight is such that it would sink in the fluid if not supported. It is placed in a float chamber and supported in such a way that as the liquid level rises around the displacer float it creates a buoyant force equal to the weight of the liquid displaced. This force is measured, and 942 since it is proportional to level, the force measurement becomes a level measurement. The device is used on sumps containing high-gravity slurries.
