Safety Definitions and Information
Do not attempt to install or use your AW Gear Meters product until you have read the safety
instructions in this section. Save this manual and keep it in an easily accessible place.
Warning means that failure to follow this safety statement may result in extensive product damage,
serious personal injury, or death.
Caution means that failure to follow this safety statement may result in minor or moderate personal
injury, property or equipment damage.
Notice is a statement that informs about installation, operation, maintenance, performance issues, or
general tips that are important but do not create a hazard or safety concern.
Unpacking
Separate the flow monitor from packaging materials and check for any visual signs of damage. If you
determine there has been damage caused by shipping, file a claim with the shipping company. If the
flow monitor appears to have been improperly assembled or does not operate properly, return it for
replacement or repair (see Limited Warranty information at the end of this manual).
Before connecting, programming, or operating the FEM-03 flow monitor, read this manual.

Operation and Programming Manual
Quick Guide
As with any precision-engineered device, always operate the FEM-03 in accordance with the
manufacturer’s instructions.
Connect to Sensor
You will connect three wires from the sensor to the back of the FEM-03:
a red wire (electrical power)
a white wire (signal), and
a black wire (ground)
Color of wires may vary.
Insert the stripped end of the red wire into upper terminal #1 and use a screwdriver to secure. Insert the
stripped end of the black into upper connection #2 and the stripped end of the white wire into upper
terminal #3. Use a screwdriver to secure these wires.
Connect to Power
Insert the female end of the 110VAC adaptor into the AC 16V input at the back of the FEM-03. Plug the
adaptor into a wall receptacle.
Basic Key Definitions
The FEM-03 has four keys for data input and programming:
DN (down)
UP (up)
SEL (select)
ENT (enter)
Use the SEL key to move the cursor to the digit you would like to change, use the UP and DN keys to
increase or decrease the value as desired, and use the ENT key to enter the information.
Programming and Data Entry
Upon power up, press the UP key to select a display to program. When you reach the display, press and
hold the ENT key. The screen shows a “P” in the lower left corner, and then prompts you to enter a
program variable or numeric entry.

FEM-03 Flow Monitor
Operation and Programming Manual
When in programming mode, the left-most alphanumeric character blinks. Use the UP or DN keys to
increase or decrease the value. Use the SEL key to move to the next selection. When you have achieved
the desired value, press ENT to store. See Programming the FEM-03 beginning on Page 21 for complete
details.
Product Description
The FEM-03 Flow Monitor is a versatile, multi-functional device that helps you track rate, flow, limit,
ratio, and other variables. The unit’s large, back-lighted LCD display is easy-to-read with up to 22
different display modes available, depending on model. The standard unit is one channel, but the
optional two-channel version allows you to monitor dual flows and display them in a number of ways:
separately, as a sum (for example in total material use), as a difference (as in fuel consumption), or as a
ratio of product A/product B. You can also use the FEM-03 to detect bi-directional flow when A and B
channel signals are available from a single flow meter.
Other capabilities include the capacity to monitor data and program the unit remotely. Four model
variations give the FEM-03 the capability of performing limit, warning and alarm duties.
Principle of Operation
After first making connections to the power source and to flow transmitter input and output, you can
choose up to 22 display modes. These include rates, totals, ratios, limits, printer status, and others,
based on the model purchased. Then input k- and t-factor values, the required engineering units,
sampling rates, gate times, limits, etc. You may also program other values such as warning/alarm limits
and ratios, depending on model.

Dimensions
Input and Output Wiring Connections
Make all connections to the FEM-03 from the back of the unit. A plug-in connector from the wall plugtype power supply, normally supplied with the unit, delivers power. If necessary, any standard AC wall
plug unit providing 13-17VAC/250mA. or 18-24VDC/250mA. may be used. A standard female plug
(2.1mm I.D. x 5.5mm O.D.) supplies AC or DC power to the FEM-03. This connector is polarity insensitive.
The factory recommends tying one of the DC COMMON terminals to earth ground, especially for DC
operation.
Make all other connections through the two rear terminal connectors. Called the “upper” and “lower”
connectors, they are removable and have ten connections each. A label on each connector shows
connection information. Refer to the Connection Diagram on page 12 for details and typical

FEM-03 Start-Up Display Messages
The FEM-03 displays an initial window at power up. After 2 seconds, the FEM-03 displays the following
message for approximately 4 seconds:
LOAD VARS Indicates the device is recalling variables from EEPROM (electrically erasable
programmable read-only memory)
TURN ON Increments each time the FEM-03 powers up
MEM LEFT Displays percent of memory life remaining (.1% increments†)
VERSION Indicates the software version installed in the FEM-03
After this display, the FEM-03 reverts to the last active Display Mode.
The FEM-03 stores variables and totalizer values in EEPROM. Minimum EEPROM life is five years with continuous
use. Memory IC can be replaced on-site.
