02 Series Electronic Flowmeter
with Scaled Pulse Output
IMPORTANT NOTICE
This meter is not approved for use with ammable liquids.
Do not use with liquids or chemicals that are not compat-
ible with the wetted materials found in the Specications
section.
This meter is not legal for trade applications.
This meter is sensitive to electrical "noise" and may not op-
erate correctly if located near certain electrical equipment.
CALIBRATION
This meter has a permanent factory calibration for light
viscosity uids. If installed and used correctly, accuracies 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. For best accuracy, provide 10 inches of pipe
upstream and 5 inches of pipe downstream. The use of pipe
sealant or PTFE tape is acceptable. Review your application
for suitability. Attach meter with arrow on outlet port pointed
in the direction of ow.
For Aluminum Housings: Using a wrench, tighten meter at
the ends.
For Nylon Housings: Hand tighten only. Avoid using metal
connections, as this could damage the housing.
OPERATION
Batch and Cumulative Totals
This meter maintains two totals: Batch and Cumulative.
The Batch total may be reset to measure ow during a
single use. The Cumulative total provides continuous mea-
surement and may not be manually reset. The Batch total is
labeled 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 Batch and Cumulative totals.
Activate the Meter
Turn the meter ON by starting uid 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 that batch
total to zero.
This meter is programmed to turn off automatically if not
used for approximately one minute.
Scaled Output Pulse
For every whole unit (Gallon or Litre) that passes through the
meter's Batch Total (TTL1), a single pulse is transmitted via
the attach cable. The White wire is signal and the Black wire
is common (GND) (See Specications).
Note: Some interface devices may not have an internal pull-
up resistor. Use a minimum 820 ohms resistor if necessary
(See Figure 1).

MAINTENANCE
Proper handling and care will extend the life and service of
this meter.
Turbine Rotor
This meter is virtually maintenance-free. However, it is
important for the rotor to move freely. Keep the meter clean
and clear of contaminants.
Remove 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.
CAUTION
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 bat-
teries 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 face-
plate on the turbine housing. To avoid moisture dam-
age, make sure the seal is fully seated. Tighten the four
screws on the faceplate.
