FTB8000A - SERIES

Pulse Meter Instructions

General Information

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 low-quality 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.

Mechanically, all FTB8000A-Series meters are the
same. The difference between -PR, -PT and Standard
meters is in the sensor. -PR meters use a solid-state,
long-lasting Hall-effect sensor, which requires power.

-PT meters use a two-wire reed switch. They provide a
dry contact closure and do not require power. Standard
meters totalize only and do not have a sensor.

the lens. The sensor turns on and off once each time
the magnet passes under it. Sensors are designed for
electronic control loads, and should not be used to switch
power loads or line voltages. See maximum current and

voltage ratings, under Specications.

Maintenance

All service should be performed by authorized distribu­tor or factory to maintain the integrity of the protective
tamper-proof wire-and-seal.

Position. FTB8000A-Series meters should be installed
horizontally with the register up. Vertical mounting will
result in some degree of under-measurement and short­ened life of the bearings.

Couplings. Couplings are included with each meter.
These provide male NPT threads the same nominal
size as the meter. The threads on the end of the meter
are IPS straight threads one size bigger than the meter
size. It is possible to thread a standard pipe coupling
directly onto the meter for close coupling, but the meter
couplings are much preferable because they provide a
union connection for meter service. Be sure to use the
included gasket between the end of the meter and the
coupling.

Inlet Conditions. No upstream straight pipe is required.
A strainer is built in to protect from solids, and should be
periodically cleaned.

Air Bleed. When the meter is rst installed, trapped air

should be removed. To do this, loosen the meter cou­plings slightly and rotate the meter to an inverted posi-

tion. Allow water to ow, then rotate the meter back

to an upright position and tighten.

Connections. -PR and -PT sensors are supplied with
a color coded output cable. See the diagram for color
codes and polarity.
Pulse Output. Both -PR and -PT sensors respond to
a magnet which rotates on the face of the meter under

Inlet Strainer. Clean the strainer yearly, or as required,
depending on water condition. Pull out the strainer or

backush the meter to loosen trapped particulates.

Calibration. Meters used for billing or billing exemp­tion may be regulated by state or local authorities. New
meters are factory-tested to meet the AWWA C-708
Multi-Jet Meter accuracy specication. Some states
require retesting at various intervals, typically eight years
for 3/4" meters, six for 1", and four for 1-1/2" and 2". Me­ters used for control should be tested every 5-10 years.
Testing can be done by local meter shops authorized for
this purpose, or can be done by the factory. For track­ing purposes, please obtain an Authorized Return (AR)
number before shipping to Omega.

Internal Parts Replacement. All of the internal parts
of an FTB8000A-Series meter lift out as a unit, after the
top has been unscrewed. The lens can then be removed
and the internal assembly lifted out. If necessary, turn
the meter upside down and tap one end lightly on a
countertop to loosen the internals. The three pieces of
the assembly can be separated by hand.

Breakage in a relatively-new meter is almost always due

to excessive ow. Compare maximum ow with the ow

rating table.

Changing Pulse Rates. After removing the meter top,
lift off the center magnet to expose the gears. If the only
change required is moving the drive gear (for example
from one gallon/pulse to ten gallons/pulse), gently pull
the drive gear off its shaft. Remove the pointer on the
target shaft and push the drive gear onto the target shaft
as far as it will go. Put the pointer on the vacant shaft
and push on.

Page 2

If a different gear set is required, follow the same pro­cedure, replacing rather than moving the drive gear. To
install a drive gear on another shaft, remove the pointer
and then press the gear down until it bottoms. Use the
pulse rate chart to determine the position.
