The FV101 Series comprises
in-line flowmeters that use the
vortex shedding measuring principle.
The fluid strikes a bluff body,
imparting alternating vortices
downstream of the bluff. This creates
a pressure on a sensor body
containing a piezoelectric crystal.
The frequency of the sensor is
proportional to the velocity of the
fluid and is amplified and converted
to a 4 to 20 mA output signal. Vortex
technology yields a meter with no
moving parts to hang up or wear.
The meter has a bright 7.62 mm
(0.3") high LED display of flow in
either liters or gallons. It can
measure flow in any direction, and
the display can be rotated 180° for
viewing convenience. The FV101
Series can be used with non-viscous,
clean, or dirty waterlike liquids that
are compatible with brass, PVDF,
and FKM. Measured fluids should
not contain long fibers or a high level
of abrasive solids. These meters are
ideal for cooling loops using water or
50% glycols, and for water-soluble
machine coolant (up to 10%). These
applications are found in most
process industries, including rubber,
steel, fabrication, manufacturing,
refining, paper, chemical, food,
petrochemical, and power. Do not
use on flammable liquids or on gases
such as air.
