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 lens. The sensor turns on and off once each time

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.

WARNING

DO NOT INSTALL

INDOOR PIPING OR

WHERE LEAKAGE

MAY CAUSE DAMAGE

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
