The oval-shaped smooth gears in
the FTB-3000 Series are used to
displace a precise volume of fluid,
which is passed through the
measurement chamber during each
revolution. The toothless design,
working with the fluid being measured,
provides a complete viscous seal
within the measuring chamber. This
sealing effect provides for greater
flow measurement accuracy.
The displacement of the fluid is
translated via a magnetic or Hall
effect pick-up into a pulse output that
is proportional to the flow.
The unique design of the FTB-3000
oval gear meter incorporates two
smooth (toothless) oval gears
positioned 90 degrees out of phase.
The measurement gears are held
together by two timing gears. The
standard meter contains no seal
between the measurement chamber
and the timing chamber. The timing
gears have a pitch diameter equal
to the outside diameter of the
measurement gears. The flow
through the meter measurement
chamber follows the path of least
resistance. Therefore, no liquid
passes through the center cavity
between the measurement gears.
The fluid is displaced from the inlet
to the outlet via the area between
the smooth oval gear and the inner
diameter of the meter housing.
Conventional oval gears have teeth
that mesh. One of the advantages
of smooth oval gears is that the
viscous flow does not get trapped
or squeezed between the gears.
Typically, oval gears need to have
cuts made in the teeth to allow high
viscosity fluids to pass. These cuts
result in a decrease in accuracy.
Accessories
Comes complete with operator’s manual and 10-point NIST calibration certificate.

precisely known volume of fluid
passing through the measurement
chamber during each rotation.
