ELECTRONIC VERTICAL FLOW METER
INSTALLATION
I.UNCRATING. When uncrating the meter, any damage
due to rough or improper handling should be reported
to the transportation firm and McCrometer. If for
any reason it is determined that the unit or parts of
the unit should be returned to the factory, please
contact McCrometer for clearance prior to shipment.
Each unit must be properly crated to prevent any
further damage. The factory assumes no responsibil-
ity for equipment damage in return shipment due to
improper packaging. The shipping crate contains the
following items:

II. INSTALLATION of McCrometer Electronic Vertical
Flow Meters varies depending upon the type and
model of meter selected for each application. The
meter must have a full flow of liquid for proper ac-
curacy. The meter installations fall into two basic
categories:
1. MODEL VF28D and VF32D are designed to
allow installation to an appropriate cast iron or
fabricated steel tee. These tees usually replace an
elbow in existing systems. Fully opened gate valves,
fittings, or other obstructions that tend to set up
flow disturbances should be a minimum of five pipe
diameters upstream from meter location.
2. MODEL VF30D TEE can be installed similar to
placing a flanged elbow or tee in the line. Installa-
tion can be made to any vertical discharge concrete
turnouts with proper anchor bolts. The meter must
be installed upright for a full flow of liquid through
the pipe to ensure proper accuracy. Fully opened gate
valves, fittings, or other obstructions that tend to set
up flow disturbances should be a minimum of five
pipe diameters upstream from the meter location.

OPERATION AND MAINTENANCE MANUAL
III. MCCROMETER products have been carefully designed
to be as maintenance-free as possible. Periodic preven-
tive maintenance, however, is highly recommended and
should be practiced according to schedule to ensure
continuous accuracy and trouble-free performance
of your propeller meters. The maintenance and
inspection procedure can also be used as a guide to
locating a problem in the unit that may be the cause
of abnormal meter operation.

Routine preventative maintenance should be performed
on all meters, which includes cleaning and an inspec-
tion of the propeller and its bearing. The intervals
between inspections depend on the water quality and
the usage of the meter. The initial inspection should
be performed after one to two years of service, to
determine the period between future inspections.
After five to ten years, the complete meter should
be inspected to ensure years of dependable service.
IV. METER HEAD ASSEMBLY should be removed from
the tee or meter tee tube by removing the meter
head bolts (#20) and lifting the entire head assembly
upward, taking care not to damage the propeller as-
sembly as it is pulled clear of the tee flanged end.
Inspect the meter head O-ring or flat gasket (#19)
for any signs of damage and replace, if necessary.
Replace the meter head assembly with a dummy cover
plate if the service line is to remain in operation.
V. WORKING AREA chosen for disassembly and re-
assembly of the meter components should be clean
to reduce the chance of dust or dirt particles being
introduced into the propeller area.
VI. PROPELLER ASSEMBLY (#1) inspection includes
cleaning the ceramic sleeve bearing (#8), separator
assembly (#12), drive magnet (#9), and the propeller
assembly (#1).
1. PROPELLER REMOVAL can be accomplished by
first removing the thrust bearing cartridge assembly
(#5). Loosen the set screw (#3) in the side of the
nose of the propeller. Remove the thrust bearing
cartridge (#5) by turning it counterclockwise while
holding the propeller in place.
2. REVERSE THRUST BEARING CARTRIDGE
(#6) must now be removed. Turn the propeller (#1)
so that the Allen wrench clearance hole is lined up
with the set screw in the side of the reverse thrust
bearing cartridge (#6). The location of the set screw
is marked by a small hole drilled in the face of the
reverse thrust bearing cartridge. With a 5/64” Allen
wrench, loosen the set screw (#7) in the reverse thrust
bearing cartridge (#6) one turn, which will allow the
set screw to protrude about 1/32” and should allow
cartridge to be unscrewed without damaging the
spindle thread. Note: If the bearing area appears
to be clogged with dirt or sediment, making it dif-
ficult to locate the set screw (#7) or to allow the
Allen wrench to fit into the set screw socket, then
the bearing area should be flushed out with water.
Insert Tool T-2402-X into the propeller through the
threaded nose. The tabs in the tool should engage in
the screwdriver slot in the end of the reverse thrust
bearing cartridge (#6). Remove the propeller assembly
(#1) and reverse thrust bearing cartridge (#6) by
turning tool T-2402-X counterclockwise, unscrewing
the reverse thrust bearing cartridge (#6) from the
spindle (#12). The propeller assembly with reverse
flow cartridge will now slide off the spindle.
WARNING: If the reverse thrust cartridge does not
unscrew easily, it may be because the set screw was
not unscrewed enough. If unscrewing of reverse
flow cartridge is continued with set screw binding
on spindle thread, damage to thread could occur.
3. WATER LUBRICATION of the ceramic sleeve
bearing (#8) is achieved by means of two openings
in the end of the thrust bearing cartridge (#5) which
allow air to be purged from the bearing area. These
should be cleared of any foreign material by running
a small wire through the holes on either side of the
screwdriver slot.
4. CERAMIC BEARING CARTRIDGE (#8) and
drive magnet (#9) should be cleaned of any foreign
material and inspected for damage. Using a bottle
brush, thoroughly clean the ceramic bearing surface
(#8) and the magnet inside diameter (#9). After clean-
ing the propeller, flush the inside out with water.
The outside surfaces of the propeller should also be
cleaned to ensure a smooth, unrestricted flow across
the surface of the propeller. Do not use an oil-based
solvent in cleaning, as damage to the assembly could
occur.
5. SPINDLE CERAMIC SLEEVE and the O.D. or
surface of the separator (#12) should be cleaned
and inspected for any substantial amount of wear.
The thrust bearing (#5) should be checked for any
damage. If it is determined that the spindle ceramic
sleeve or separator (#12) are worn sufficiently, the
separator/support spindle assembly (#12) should be
replaced.
6. SEPARATOR/SUPPORT SPINDLE ASSEMBLY
(#12) can be removed for replacement by removing
the four mounting screws (#13) which thread into the
drop pipe. Separator o-ring (#14) should be replaced
and the new o-ring (#14) covered with a thin coat of
silicone grease. The separator and support spindle
assembly (#12) can then be replaced in the front of
the drop pipe (#7) with a firm push, gently rotating
the assembly at the same time. Replace and tighten
the four mounting screws (#13).
7. PROPELLER INSTALLATION is accomplished
by following these steps:
a) The reverse thrust cartridge set screw (#7)
should be protruding 1/32” out of the reverse thrust
cartridge so it will not bind up on the spindle thread.
Note: Look through the hole in the reverse thrust
cartridge to be sure the set screw is not showing.
b) Slide the propeller assembly onto the support
spindle (#12) until the reverse thrust bearing cartridge
(#6) contacts the threads on the end of the spindle
(#12). If you feel any resistance when threading
the reverse thrust cartridge, stop at once and check

30119-21 Rev. 4.6/07-09
5
to be sure the set screw is not binding on the thread.
Be careful not to cross-thread the reverse thrust bearing
cartridge.
c) Thread the reverse thrust bearing cartridge on the
spindle (#12) until the trailing edge of the propeller contacts
the drop pipe (#7).
d) Set the proper end play by using tool T-2402-X to
loosen the reverse thrust bearing cartridge (#6) approxi-
mately one half to one full turn counterclockwise. There
should be minimal clearance between the drop pipe (#7)
and trailing edge of the propeller, however the propeller
must not contact the drop pipe. Remove tool T-2402-X
to determine the location of the set screw in the reverse
thrust cartridge and then reinsert the tool and hold it
while turning the propeller until the clearance hole in the
propeller lines up with the set screw in the reverse thrust
bearing cartridge.
e) Tighten the set screw (#7) in the side of the reverse
thrust bearing cartridge (#6).
8. THRUST BEARING CARTRIDGE ASSEMBLY (#5)
should be inspected for damage and replaced in the
nose of the propeller. The thrust bearing cartridge (#5)
is used to adjust the amount of longitudinal end play
of the propeller assembly on its spindle (#12), which
should be about 1/64”. End play can be adjusted after
the set screw (#3) in the side of the propeller (#1), is
loosened and then by turning the thrust bearing cartridge
assembly (#5) clockwise until it tightens against the end
of the support spindle (#12), then turning thrust bearing
cartridge (#5) counterclockwise 1/8 of a turn. Tighten
set screw (#3). Check the longitudinal end play of the
propeller to ensure it’s not excessive and does not allow
the propeller (#1) to contact the drop pipe (#7). Check
the clearance between the propeller (#1) and drop pipe
(#7). The clearance should be minimal and the propeller
assembly (#1) must spin freely.
9. PROPELLER BEARING (#8) can be checked for exces-
sive radial play by rocking the propeller (#2) gently from
side to side on the spindle (#12). Some play is required
for proper operation of the water lubricated ceramic sleeve
bearing.
VII. SENSOR AND FC101 DIGITAL INDICATOR TOTAL-
IZER
1. FC101 DIGITAL INDICATOR (#34) should not be
removed from the meter unless battery or sensor replace-
ment is required. If the unit must be removed, proceed
as follows:
2. FC101 (#34) can be removed from meter head by
removing the four screws (#32) then slightly lifting unit
up and turning over to disconnect the 2-lead sensor wires
from the bottom of the FC101. If the meter is equipped
with a transmitter, the transmitter wires must also be
disconnected.
3. SENSOR HOUSING should be removed only if
replacement is necessary. It can be taken out of
the separator after removing the propeller (Section VI
Step 1) and the separator/support spindle (Section VI
Step 6). Using an Allen wrench, loosen the sensor
housing set screw in the side of the sensor housing.
Slide the sensor housing and wire assembly out of
the separator.
4. BEFORE REPLACING THE SENSOR, be sure
the separator is dry. Slide sensor housing and wire
assembly into the separator until it stops against the
inside of separator. Note: It does not make any
difference what rotation position sensor is installed;
however, wire must be positioned toward back (open
end) of separator. Tighten the sensor housing set
screw to hold the sensor housing snugly in place.
DO NOT OVERTIGHTEN. Feed the sensor wire up
through the drop pipe and out the meter head.
5. LITHIUM BATTERY should offer 6 to 10 years
of operation. The FC101 has a low battery display
that comes on when approximately six months of life
are remaining. The battery should test between 2.8
to 3.6 volts.
If battery replacement is necessary, refer to the In-
stallation, Operation and Mantenance manual provided
with the FC101.
NOTE: Batteries should be disposed of in an
environmentally safe manner.
6. THE FC101 DIGITAL INDICATOR-TOTALIZER
(#34) can now be installed in one of four positions for
more convenient reading with four screws (#32).
VIII. PRIOR TO INSTALLING METER
1. PROPELLER ASSEMBLY (#1) should be dipped
in water to lubricate the propeller ceramic sleeve
bearing (#8). Spin the propeller (#2) gently to make
certain the meter operates smoothly and no bind or
drag is apparent.
2. FC101 (#34) and sensor (#15) should be checked
to be sure they are connected and that the battery
is good. Turn the propeller by hand at a fairly fast
even speed and the indicator display should display
a flow rate.
3. METER HEAD O-RING OR GASKET (#19) should
be inspected for any sign of damage and covered
with a thin coat of silicone grease (O-ring only). The
meter can now be installed in the service line. When
replacing the meter on the line, make certain that
the top of the welding saddle is smooth and free of
any foreign material. Make certain that no foreign
materials are attached to the inside of the service
line pipe, as any flow disturbance or obstructions
may affect the accuracy of the meter.

NOTES
IX. ORDERING PARTS OR RETURN TO FACTORY
Inspection of all meter components that may be
replaced in the field has been accomplished at this
point. Should any of the meter parts, upon inspection,
appear to be damaged or excessively worn, they must
be replaced to ensure proper meter operation and
prevent further damage. Costs for replacement parts
not covered by warranty are available by contacting
the factory. If it is determined that the meter should
be returned for repair, please notify McCrometer prior
to shipment. Each meter must be properly packaged
to prevent damage to the meter in shipment.
