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. Installation to metal connections is not
recommended. Install as follows:
1. Apply teon tape to all ttings (customer supplied).
2. Install meter in the arrow direction of ow.
3. Hand-tighten tting on both ends of the Flow Meter.
DO NOT overtighten with tools, which will damage
the plastic housing.
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 briey to switch between the
batch and cumulative total.
Activate the Meter
Turn the meter ON by starting water ow or briey
pressing the DISPLAY button. The meter will display the
batch or cumulative total from last use.
Press DISPLAY briey 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.
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.
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 specied parameters. Do not operate this ow
meter if incoming pressure exceeds 80 psi.
Should inlet pressure exceed 80 psi, the optional HydroLogic pressure regulator (HL 10077) is required for
operation.
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.
CAUTION: Blowing compressed air through the turbine assembly could damage the rotor.
Do not contact your dealer or distributor for warranty issues.

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.
