Not recommended for installation indoors or anywhere leakage may cause damage.
商品説明
The FTB8000A Series has been
upgraded. Please see the FTB8000B Series as a possible substitute or contact
our Flow department.
IMPORTANT NOTE:
These water meters are not
recommended for installation
indoors or anywhere leakage
may cause damage.
The FTB8000A 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 FTB8000A 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 two-wire reed switch. They
provide a dry contact closure and do
not require power. Basic FTB8000A
meters totalize only and do not have
an output. Never install water
meters above or over areas where
leakage would cause damage.
注: Meters supplied with MNPT couplings and complete operator’s manual. IMPORTANT NOTE:These water meters are not recommended for installation indoors or anywhere leakage may cause damage.
