Copper Float, Pan Type, 4.0in/102mm Diameter

The Copper Floats are hollow and made from spun copper and weighted to allow them to float at the correct depth. An eye-bolt is mounted on top of the float to attach a float line or tape, and a small breather hole is provided on the top to equalize inside and outside pressure. The copper floats are painted with durable aquamarine urethane that inhibits aquatic growth.

Float sizes range from 2.5 to 16 inches diameter. Larger floats provide greater operating force for a given water level change, overcoming instrument friction for greater measurement resolution. However, this requires a larger diameter float well.
