GENERAL INFORMATION, INSTALLATION and MAINTENANCE
GENERAL INFORMATION
FTB8000B-Series 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 Pu lse Output. Both PR and PT sen sors respond to
a magnet that rotates on the face of the meter under Position. FTB8000B-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.

the magnet passes under it. Sensors are designed for elec-
tronic control loads, and should not be used to switch power
loads or line voltages. See maximum current and voltage
ratings, under Specications.

Caution: These water meters are
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.
MAINTENANCE
Omega recommends all service to be performed by an autho-
rized 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, de-
pending on water condition. Pull out the strainer or backush
the meter to loosen trapped particulates.
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.
Calibration. Meters used for billing or billing exemp-
tion may be regulated by state or local authorities. New

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 Connections. PR and PT sensors are supplied with a color

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.

The 4 P/G rate requires a special magnet, placed on the x0.1 dial, as shown above.
ister with the Six-Digit Totalizer, and then reading clockwise around the small dials. In the example below, the Six-Digit Totalizer reads 13,800 (138 x 100), and the dials read 60 (6 x 10), 2 (2 x 1), and .4 (4 x .1) respectively. The Total
Flow is 13,862.4 gallons.
