02 Series Electronic Flowmeter
with Scaled Pulse Output
IMPORTANT NOTICE
This meter is not approved for use with flammable liquids.
Do not use with liquids or chemicals that are not compat-
ible with the wetted materials found in the
Specifications
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 fluids. 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 flow.
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 flow 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
briefly to switch between
Batch
and
Cumulative
totals.
Activate the Meter
Turn the meter ON by starting fluid 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
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 Specifications)
.
Note:
Some interface devices may not have an internal pull-
up resistor. Use a minimum 820 ohms resistor if necessary
(See Figure 1)
