The FTB8000B 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

the gear is placed. Changing the
pulse rate requires no special tools
and can be done in the field.

Mechanically, all FTB8000B 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
FTB8000B meters totalize only and
do not have an output. Never install
water meters above or over areas
where leakage would cause damage.
