GENERAL INFORMATION and SPECIFICATIONS
GENERAL INFORMATION
FTB-630 Series turbine meters are dry-register mechanical
totalizers that offer accurate, economical reading of high
flows with low pressure loss. The horizontal-axis turbine
drives a vertical shaft, which is magnetically coupled to the
sealed register.
In addition to mechanical totalizing, registers can be
equipped with magnetic pulse reed sensors well suited for
remote total-izing, pacing of electronic metering pumps,
and water treat-ment applications.
FEATURES

Security bolt and seal
Bodies are manufactured of tough cast iron and
epoxy coated for protection. Tungsten steel shafts and jewel
bearings further enhance the durability of these meters.
Simple removal of the top flange brings out all parts for
inspection, repair, or replace-ment. The meter has a tamper-
evident seal to call attention to unauthorized access.

INSTALLATION
The following installation recommendations are adapted
from the American Water Works Manual M6, and will result
in the best meter life and accuracy.
Piping Conditions. It is recommended that the meter be
installed with at least ten diameters of straight pipe
upstream and five diameters downstream from elbows,
tees, crosses, valves, and other fittings. If less straight pipe
is available, or if debris are likely to go through the meter,
installation of a stan-dard plate-type strainer directly
upstream is recommended. If a basket-type strainer is
used, it should be located at least five diameters upstream.
Avoid conditions of trapped air or partially-filled pipe. This
can occur when there is low flow and open discharge near
to the meter.
10X Dia. 5X Dia.
Flanges. The FTB-630 Series meter is compatible with any
standard 150 lb. ANSI drilling, flat or raised face. Take care
that gaskets (included) do not protrude into the meter due
to misalignment. Adhering the gasket to the meter flange
with gasket adhesive is a good practice that will aid
installation.
Position. FTB-630 Series are all-position meters, and can
be installed horizontally or vertically. Horizontal with
register facing up is recommended when possible.

MAINTENANCE AND REPAIR
CAUTION: Before breaking the tamper-
evident seal on your meter, be sure that
you are in compliance with any regulatory
requirements (if applicable).
Register Removal. Clip and remove the copper security wire
from the ange bolt (see Caution note). Remove the security
pin that holds the lid in place, twist the lid and lift it off. Lift the
register free from the meter, noting orientation.
Field-Changing Pulse Rates. For the contacting head option,
FTB-630 Series meters use a meter-mounted reed switch to
provide a two-wire dry contact. To add a reed switch or change
your pulse rate in the eld, remove the register as described
above. Then:
1. Choose desired pulse rate and switch position.

2. Insert the gray reed switch sensor into the side of
the register nearest the dial with desired pulse rate.
4. Replace the register with the solid plastic tab seated
in the retaining ring to prevent rotation.
5. Thread the reed switch cable through the channel
in the retaining ring to the outside of the meter.
6. Reverse the procedure to close up the meter.
Recalibration. For meters used for revenue-billing purposes,
some states require periodic calibration checking. This type
of turbine meter is most commonly checked every four years.
Testing may be done by a local mobile meter service or in a
private or municipal meter shop. Changes in calibration should
be made at an authorized meter shop.

Turbine Insert Replacement. The entire turbine insert comes
out as a unit without removing the meter from the pipe. Carefully
noting position and retaining parts for reassembly...
1. Remove the lid and register as described.
2. After relieving pressure inside the meter, remove
the four ange hex-screws and washers.
3. Lift the ange and insert out in one piece, rocking
gently to break the seal.
4. Remove the four retaining ring screws, and lift
the retaining ring and ange off the turbine insert.
5. Remove and replace the large O-ring around the
top opening of the meter body.
6. Reassemble the retaining ring and ange on top of
the new insert. Be sure the alignment notch in the
retaining ring is directly above the screw in the
insert’s top plate.
7. Replace the entire mechanism in the meter body
with the drilled screw head in the same corner as
the security pin.
8. Replace the lid with a twist of the wrist, insert
the security pin in the tiny hole in the retaining ring,
and thread the security wire through the screw
head and the security pin. Afx lead seal and crimp.
