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.

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.
