IMPORTANT NOTICE
Use this meter with water, DEF or similar fluids.
Do not use with flammable liquids, fuels or chemicals
that are not compatible with the wetted materials
found in the Specifications section.
This meter is not legal for trade applications.
The meter is sensitive to electrical “noise” and
may not operate correctly if located near some
electrical equipment.
CALIBRATION
This meter has a permanent factory calibration
for light viscosity fluids. If installed and used cor-
rectly, inaccuracies of no great er than ±5% will be
obtained.
INSTALLATION
This meter may be installed in-line either horizon-
tally or vertically or at the end of the hose adjacent to
the nozzle, if present. Installation to metal connections
is not recommended.
The use of pipe sealant or PTFE tape is accept-
able. Review your application for suitability.
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.
Batteries included.
OPERATION
Batch and Cumulative Totals
The meter maintains two totals. The batch total
may be reset to measure flow during a single use.
The cumulative total provides continuous measure-
ment 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 briefly to switch
between the batch and cumulative total.
Activate the Meter
Turn the meter ON by starting water flow or briefly
pressing the DISPLAY button. The meter will display
the batch or cumulative total from last use.
Press DISPLAY briefly to display the batch total.
Hold the DIS PLAY 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.
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.
Blowing compressed air through the turbine
assembly could damage the rotor.

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 cumula tive totals reset to zero but the
factory calibration is re tained.
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. Reseat batteries, if necessary, and position the
faceplate on the turbine housing. To avoid mois-
ture damage, make sure the seal is fully seated.
Tighten the four screws on the faceplate.
