Variable area flow meters, also known as rotameters,
consist of a vertical tube with an inlet at one
end and an outlet at the other. Inside the tube
is a float whose density is greater than the density
of the fluid.
As the fluid passes through the tube at varying
speeds, the float rises or falls, maintaining a
dynamic balance between the upward and downward
forces acting on the float and the fluid. The height
of the float in the tube indicates the flow rate.
The metering tube includes a scale where flow rate
can be read manually.
Able's wide range of standard VA meters and accessories
cater for many applications requiring the measurement
and control of liquids and gases. However, we are
also able to design and manufacture solutions to
fit more specific application needs where required.
Various outputs are available such as indication
only, alarm switch points or continuous 4-20mA depending
on requirements.
