SAFETY WARNINGS
SAFETY WARNINGS
When installing, operating, and maintaining McCrometer equipment where hazards may be present, you must protect
yourself by wearing Personal Protective Equipment (PPE) and be trained to enter conned spaces. Examples of conned
spaces are manholes, pumping stations, pipelines, pits, septic tanks, sewage digesters, vaults, degreasers, storage tanks,
boilers, and furnaces.
You must follow all state and local laws, as well as Occupational Health and Safety Administration (OSHA) regulations
concerning Personal Protective Equipment, conned-space entry, and exposure to bloodborne pathogens. Specic
requirements can be found in the OSHA section of the Code of Federal Regulations: 29 CFR, 1910.132 - 1910.140, Personal
Protective Equipment; CFR Title 29, Part 1910.146, Permit-Required Conned-Spaces; and 29 CFR, 1910.1030, Bloodborne
Pathogens.
WARNING!
Never enter a conned space without rst testing the air at the top, middle, and bottom of the space.
The air may be toxic, oxygen decient, or explosive. Do not trust your senses to determine if the air is safe.
You cannot see or smell many toxic gases.
WARNING!
Never enter a conned space without the proper safety equipment. You may need a respirator, gas
detector, tripod, lifeline, and other safety equipment.
WARNING!
Never enter a conned space without standby/rescue personnel within earshot. Standby/rescue
personnel must know what action to take in case of an emergency.
WARNING!
Pressurized pipes should only be tapped, cut, or drilled by qualied personnel. If possible,
depressurize and drain the pipe before attempting any installation.

STEP 2: Remove the totalizer assembly.
Remove the entire totalizer or indicator-totalizer register assembly. Register models with totalizers have four bonnet
screws and models with both the indicators and totalizers have four bonnet screws and two register screws. Remove
the shaft.

For ML and LP meters: Remove the V-shaft by
loosening the two screws holding the V-shaft from
the inside of the meter head.
For MLand LP meterswith extensions andforOF andVF
meters:Pull vertical shaft out only enough (approximately
1”) for removal of miter gear frame assembly so that the
vertical shaft can be used later for pulling the sensor input
cable out of the drop pipe.
STEP 1: Remove the owmeter.
Remove pressure from the pipeline.
Remove the entire owmeter from the pipeline.
CAUTION!
Never remove a meter or top plate assembly while the line is under pressure!

Caution: The gearbox oil will begin draining as
soon as the seal is broken.
Note: See your ow meter’s IOM manual for
instructions on removing the propeller.
For VF meters:
Remove the propeller and the separator-spindle
assembly.

For ML and LP meters: Push the sensor assembly
through the back of the gearbox all the way into
the separator/spindle assembly. Rotate the sensor
assembly so that the sensor cable can be fed
through gearbox up over the meter head. Put a thin
lm of silicon grease on the O-ring and secure the
back plate of the gearbox with four screws.
Note: Do not twist the back plate. This can cause the
O-ring to be pinched and the meter to leak.
For OF and 24” to 54” ML meters: Attach pulling
xture T-2730-2 to bottom tip of existing vertical
shaft assembly. Tighten both set screws on the
xture with a 0.062 Allen wrench for a secure
connection to the vertical shaft tip. Loop sensor
cable through hook on xture and secure with a
small piece of tape. Keep the sensor cable tight to
allow passage through drop pipe bushings.
For VF meters: Push the sensor assembly all the
way into separator/spindle assembly and then
tighten the set screw to secure the position of the
sensor assembly.
Note: The sensor cable must be positioned as
shown.
Then tie the sensor cable to the magnet end of the
vertical shaft to assist in pulling the cable through.
Leave approximately a 4” tale from the knot to the
end connector so that magnet and cables can pass
through the drop pipe end. At last, reinstall the
propeller and separator/spindle assembly.
STEP 4: Reassemble the gearbox assembly.
Before you begin, make sure the gearbox or drop pipe and separator/spindle assembly are dry and free of oil.

STEP 5: Connecting the sensor wires
The connection shown below is typical of all Water Specialties Electronic Propeller Flow Meters.
a. Clean the meter head surface of all dirt, glue, gaskets, etc.
b. Verify that an O-ring is installed at the bottom of the electronic register base plate.
c. Connect the sensor cable to the in-line terminal blocks.
d. Secure the electronic register to the meter head with the four 1-1/4”long screws provided (Figure18).
e. Spin the propeller and verify that the rate display responds.

NOTE: When the FlowCom is attached to the base plate, it can be oriented in four possible ways. This aects
how the register is read when the owmeter is installed in the pipe. Select the orientation you prefer as shown

INSTALLATION
If the submergible remote mount assembly has not already been
installed in the meter head plate, you need to assemble it. Use
Figure 7 at right as a guide for this step.
a. Follow steps 1 through 4 from section 2.1.
b. Pull the FlowCom remote cable through the assembled
submergible remote mount kit and out through the bottom.
c. Using the inline terminal, connect the FlowCom remote cable
to the sensor cable wires, matching the red wires and the
black wires.
d. Guide the inline terminal block into the neck of the drive
shaft column and screw the submergible remote mount
kit assembly into the neck of the drive shaft column while
holding the remote mount cable. Holding the remote mount
cable will prevent the twisting of the sensor cable inside the
drive shaft column which can cause the cable termination of
the inline terminal block to be pulled apart.
WARNING!
Over tightening the cable compression seal will damage the internal conductors, causing them to be crushed
and shorted together, preventing proper operation.
e. Tighten down the compression on the submergible assembly kit. Tighten only hand tight plus one half turn.
STEP 1: Install submergible remote mount kit in the meter head plate

*IMPORTANT NOTES: 4-20mA Current Loop In Presence Of Environmental Noise (VFDs, RF Transmitters etc.)
• The +24VDC Power Supply must be isolated by insuring that the -24VDC is NOT tied to earth ground
• To ensure that the power supply for 4-20mA output loop is properly isolated from the earth ground, check voltage
between earth ground and negative power supply terminal. You should see oating values, in approximate range of
4V to 8V.
• The shield for theWiegand sensor must be connected to earth ground. Insure the shield for the sensor is not connected
to VSS.
• To locate good earth ground, measure impedance between any of the non-powered 4-20mA terminals and the chosen
ground spot. The ohmmeter should show a very low reading, lower than 1Ω.

4.1 Accessing The Conguration Menu
Hold the magnetic wand as noted in Figure 27 below. After ve seconds the register will display “Loc-Code”. A lock code of
01000 is required to enter the conguration menu. Use the magnetic wand to input the lock code and then pass the
wand over the“P” symbol to submit the lock code and the conguration menu will appear. The register will switch back to
run mode by either selecting the run mode from the conguration menu or by not activating the conguration menu for
sixty seconds.

4.2 Document Changes
Each register ships with two silver identication labels. The label contains basic setting information for the register. If
changes are made to the register settings the labels should be marked as required. Forward the changes to the factory so
the records can be updated.
