The FTB8000HW Series meters use
the multi-jet principle, which has
been an internationally accepted
standard for many years. This type
of meter is known for its wide range,
simplicity, and accuracy in lowquality water. The impeller is
centered in a ring of jets, with inlet
jets on one level and outlet jets on
another. A gear train drives the
register totalizer dials. For pulse
output, one of the dials is replaced
by a gear, which turns a magnet
that is detected by an encapsulated
sensor threaded into the outside of
the lens. Pulse rate is determined
by the gear and the dial on which
F-X
F
the gear is placed. Changing the
pulse rate requires no special tools
and can be done in the field.
Mechanically, all FTB8000HW
meters are the same. The difference
between the -PR, -PT, and standard
models is in the sensor. -PR model
meters use a solid state, longlasting Hall-effect sensor, which
requires power. -PT model meters
use a 2-wire reed switch. They
provide a dry-contact closure and
do not require power. Basic
FTB8000HW meters totalize only
and do not have an output. Never
install water meters above or over
areas where leakage would cause
damage.
