Flow Meter (High Capacity) for BIGboy™
IMPORTANT NOTICE
Use this meter for water only. Do not use to meter fuel
or chemicals.
This meter is not legal for trade applications.
The meter is very sensitive to electrical “noise” and
may not operate correctly if located near some
electrical equipment.
CALIBRATION
This meter has a permanent factory calibration for
measuring water. If installed and used correctly,
inaccuracies of no greater than ±5% will be obtained.
INSTALLATION
This meter may be installed in-line either horizontally
or vertically or at the end of the hose adjacent to the
nozzle, if present. Installation to metal connections is
not recommended. Install as follows:
1. If necessary, remove nozzle from hose.
2. Apply pipe sealant to all threaded connections.
3. Attach meter to hose with arrow on outlet port
pointed in the direction of ow.
4. If necessary, attach nozzle to meter
5. Hand tighten the meter at the housing ends. Do not
use a wrench or similar tools to tighten the meter
housing. The plastic housing could be damaged.
OPERATION
Batch and Cumulative Totals
The meter maintains two totals. The batch total
may be reset to measure ow during a single use. The
cumulative total provides continuous measurement and
may not be manually reset. The batch total is labeled
as TTL1. The cumulative total is labeled TTL2.
When the cumulative total reaches a maximum reading
of 9999, it will automatically reset to zero.
Press the DISPLAY button briey to switch between the
batch and cumulative total.
Activate the Meter
Turn the meter ON by starting water ow or briey
pressing the DISPLAY button. The meter will display the
batch or cumulative total from last use.
Press DISPLAY briey to display the batch total. Hold
the DISPLAY button down for three seconds to reset the
batch total to zero.
The meter is programmed to turn off automatically if
not used for about one minute.
MAINTENANCE
Proper handling and care will extend the life and
service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. However, it is
important the rotor moves freely. Keep the meter clean
and free of contaminants.
If the rotor does not turn freely, apply a penetrating
lubricant on the rotor, shaft, and bearings. Remove any
debris or deposits from the rotor using a soft brush or
small probe. Be careful not to damage the turbine rotor
or supports.
CAUTION: Blowing compressed air through
the turbine assembly could damage the rotor.
Batteries included.

WARRANTY
A One Year Warranty comes with each unit against manufacturer’s defects. This does not include clogging due
to lack of regular maintenance or excessive sediment and/or contaminants in water. This warranty also excludes
damage to units caused by using the unit outside of the specied parameters. Do not operate your lter unit if
incoming pressure exceeds 80 psi or there is problem with water hammer spikes. If unsure of water pressure,
check with a pressure gauge available at your dealer or hardware store. Install the optional pressure regulator if
inlet pressure is above 80 psi.
Do not contact your dealer or distributor for warranty issues.

Battery Replacement
The meter is powered by two AAA alkaline batteries
which may be replaced while the meter is installed.
When batteries are removed or lose power, the batch
and cumulative totals reset to zero but the factory
calibration is retained.
If the meter display becomes dim or blank, replace the
batteries as follows:
1. Remove the four Phillips-head screws from the face
of the meter and lift the faceplate from the turbine.
2. Remove the old batteries and clean any corrosion
from the terminals.
3. Install new batteries. Make sure the positive post is
in the correct position.
4. When the batteries are replaced, the faceplate will
power ON. Check the display to ensure normal
functions have resumed before assembling again.
5. Re-seat batteries, if necessary, and position the
faceplate on the turbine housing. To avoid moisture
damage, make sure the O-ring is fully seated.
Tighten the four screws on the faceplate.
