FG =
Force of float
weight
depending
on the float
material
constant
FA =
Force of lifting
depending on the
medium density
constant
FS
= Force
of the stream
depending
on the geometric
float form
constant
The forces are
constant
because:
The area between
float and tube
is not constant.
Therefore the
position of the
float is a
direct
indication of
the flow rate.
