Copper Floats
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.

Plastic Floats
Plastic floats come in three basic styles depending
on diameter. The cylinder type is designed for wells,
boreholes and small diameter stilling wells. The ball
type is for 3" thru 8" diameters and are popular because
they don't easily get hung up on the sides of a
corrugated pipe stilling well. The pan type are for
larger diameters and offer the most accuracy because of
their size. All plastic floats are properly weighted to
allow them to float at the proper depth.

Plastic Float Hanger
The Plastic Float Hanger is used to suspend the
plastic float from the end hook at the end of a float
tape.

Beaded
Cable
The Standard Beaded Float Line is geometrically
wound, non-twisting, 0.040 inch diameter,
stainless-steel cable. The line has beads crimped on
at uniform intervals which match the recesses in the
float pulley for non-slip operation.

Tapes,
Stainless Steel, Perforated
The Graduated Float Tape can be used when a
visual reading of water level heights is desirable.
It is graduated in feet, tenths, and hundredths, or
in meters, decimeters, and centimeters, punched at
0.2 foot intervals to fit shaft encoders and ADR
float wheels and 0.5 foot intervals to fit A-71
level recorders. A splined pulley/float wheel
provides sprocket-like, non-slip operation, and an
adjustable indicator provides an index for direct
reading from the tape.
