GENERAL INFORMATION, INSTALLATION and MAINTENANCE

GENERAL INFORMATION

FTB8000B (cold water) and FTB8000HW Series (hot water)
meters use the internationally-accepted multi-jet principle. A
gear train drives the register totalizer dials. For pulse output,
one of the pointers is replaced by a magnet arm, which is
detected by an encapsulated sensor attached to the outside
of the lens.

PR meters use a solid-state, long-lasting Hall-effect sensor,
which requires power. They are suited for use with Omega
controls and metering pumps (LMI for instance) that have
sensor power.

PT meters use a reed switch. They provide a dry contact clo­sure and do not require power.

Standard meters do not have a sensor, and they totalize
only.

INSTALLATION

Position. FTB8000B and FTB8000HW 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. No upstream straight pipe is
required.

Caution: These water meters are

WARNING

DO NOT INSTALL

METER IN OVERHEAD

INDOOR PIPING OR

WHERE LEAKAGE

MAY CAUSE DAMAGE

not recommended for installation
in uninsulated suspended ceil­ings where freezing is possible,
or in any overhead indoor piping

conguration where leakage may

cause damage.

Couplings. Male NPT threaded couplings are included with
each meter. The threads on the end of the meter are IPS
straight threads one size bigger than the meter size. Though
it is possible to thread a standard pipe coupling directly onto
the meter for close coupling, the included 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.

Connections. PR and PT sensors are supplied with a color
coded output cable (see diagram, page 4). Optional connec­tors can be ordered to plug directly into an Omega control or
LMI metering pump.

Pu lse Output. Both PR and PT sen sors respond to
a magnet that rotates on the face of the meter under
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

Omega recommends all service to be performed by an autho­rized distributor or the factory to maintain the integrity of the
protective tamper-proof wire-and-seal.

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 exemp-
tion may be regulated by state or local authorities. New

me ters are fac tor y -tested to mee t the AWWA C-708

Mu lti-Jet Meter accuracy spe cif ication. 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 the factory or local meter shops authorized
for this purpose. Please contact Omega before sending

meter in for calibration or servicing.

Setting Your Pulse Rate. The pulse rate is determined by which
sensor was ordered from the factory (single reed switch, dual
reed switch, or single Hall-effect) and by the dial on which the
magnet pointer is located. The pointer is set at the factory, but

can be changed in the eld as follows.
In the table below: 1) Locate your meter size (Column 1); 2)
Find your desired pulse rate (Column 2); 3) Note the magnet
pointer position (Column 3); 4) Move the magnet pointer to

the appropriate dial position (using the detailed instructions

below the table); 5) Use the appropriate Connection Diagram
(from Column 4) to wire the sensor to your remote device (using

diagrams on page 4).

Sample Set-Up. A 1” meter is shown with the magnet

pointer set at the x10 dial, with a pulse rate of 100 Gal­lons per Pulse (that is, 10 increments on the x10 dial, or
10x10=100 Gal/Pulse).

Moving the Magnetic Pointer. Remove meter top and lens,

taking care not to lose the sealing ring. With ngers, lift the

magnet pointer off its shaft and remove the plain pointer from

the target dial. Reverse their positions and press them rmly

into place. Securely seat the sealing ring and replace the lens,
matching the tab on the lens to the notch on the meter to align
the sensor with the magnetic pointer dial. Thread the meter top
on and tighten.

†NOTE: A special magnet (available from the factory) is required
to achieve a rate of 4 pulses per gallon. It should be placed on

the x0.1 dial, with non-magnetic pointers on the remaining dials.

Otherwise, the procedure is the same.

The 3/4” meter has a fourth dial,
as shown above. The x0.01 dial is
used for 20 P/G and 10 P/G rates.
Note: The 3/4” meter has a 5 digit
totalizer.

around the small dials. In the example below, the Six-Digit
Totalizer reads 13,800 (138 x 100), and the dials read 60

Flow is 13,862.4 gallons.
