4. Selecting a Location
•
•
The FMG-3000 requires a full pipe and a fully developed turbulent flow profile for accurate measurement.
If the piping system harbors air pockets or bubbles, take steps to locate the sensor so the air pockets will not contact the
electrodes.
In vertical installations, assemble the unit so the conduit ports are facing downward. This prevents condensation inside the conduit
from being directed into the electronics housing.

Locating the sensor in a trap or where the
flow is upward helps to protect the sensor
from exposure to air bubbles when the
system is in operation.
NOTE: The system must be designed to
keep the sensor wet at all times.
O.K.
O.K.
O.K.
Vertical flow is OK IF the pipe remains full at all times.
These configurations are not
recommended because it is difficult to
keep the pipe full.
In a gravity-flow system, the tank must be designed
so the level does not drop below the outlet.
This causes the pipe to draw air in from the tank.
If air bubbles pass across the Magmeter electrodes,
the output will become erratic.

5. FMG-3000 Magmeter Configuration
Whether using the FMG-3000 (frequency or 4-20 mA output) the wiring terminals located on the inside of the yellow cover are identical.
All of the connections from the Magmeter to external equipment (Datalogger, Chart Recorder, Flow meter, etc.) are made at the large
4-position terminal connector.
When the cover is removed the wiring from the sensor can be seen connected to the smaller terminal block. These connections should
always remain connected to prevent inadvertent damage or miswiring.
The terminals on the FMG-3000 Magmeter are designed for conductors from 16 AWG to 22 AWG.

•
•
The directional arrow on the body of the sensor must be pointed DOWNSTREAM.
The FLOW arrow decal can be placed directly on the pipe to identify the direction of flow.
Use a cable gland or a liquid tight connector to seal the cable ports from water intrusion.
The yellow housing may be reversed to align the conduit ports as required.
If the Magmeter is installed on a vertical pipe, the conduit ports should be turned to point downward.
This will prevent condensation from being channeled into the enclosure.
Use plumber's tape or a suitable sealant on cable ports.

6. General Installation and Grounding Tips
Sensor conditioning
The Magmeter output signal may be unstable immediately after installation. Allowing the sensor to soak in a full pipe (or in any
container of water) for 24 hours will stabilize the performance.
•
Very low conductivity fluids may require a longer conditioning period. (The Magmeter may not operate properly in fluids where the
conductivity is less than 20 µS/cm.)
Grounding
The FMG-3000 Magmeter is unaffected by moderate levels of electrical noise. However, in some applications it may be necessary to
ground portions of the system to eliminate electrical interference. The grounding requirements will vary with each installation.
One or more of the following steps may be
applied if the FMG-3000 Magmeter is affected by
electrical noise:
Do not terminate
shield at Magmeter
3.
1.
ꢀ The ground terminal on the outside of the
yellow housing is connected internally
to the grounding ring at the tip of the
sensor. Connect a wire (14 AWG/1.5 mm2
recommended) from this terminal directly to a
local Earth ground.

ꢁ Install fluid grounding devices immediately
upstream and downstream of the Magmeter.
Connect the fluid grounds to the Earth ground
terminal on the FMG-3000.

Use flanged grounding rings or metal
electrodes on plastic pipes, or metal clamps
on metal pipes.
Fluid grounds must be in direct contact with
the fluid, and as near to the Magmeter as
possible.

7. Wiring the FMG-3002 and FMG-3102 Magmeter with 4-20 mA Loop Output
The FMG-3002 and FMG-3102 Magmeters are traditional 2-wire passive 4-20 mA loop transmitters.
•
•
•
External loop power (24 VDC 10%) is required.
The maximum loop resistance the Magmeter can accomodate is 300 Ω.
All FMG-3002 and FMG-3102 Magmeters are shipped from the factory with the 4-20 mA output scaled for 0 to 5 m/s (0 to 16.4 ft/s).
The Calibration charts on pages 6-10 list the 20 mA setpoint for each installation fitting. Use this information to program the 4-20
mA range of the loop device (PLC, Datalogger, recorder, etc.)

8. Wiring the FMG-3001 and FMG-3101 with Frequency output
•
•
The FMG-3001 and FMG-3101 Magmeters output an open collector frequency signal.
A 10 KΩ pull up resistor must be connected between terminals 1 and 2 if the magmeter is used with third-party equipment..

10. Maintenance
The FMG-3000 series Magmeter requires very little maintenance. There are no user-serviceable components in the Magmeter.
•
•
•
If the fluid contains deposits and solids that may coat the electrodes, a regular cleaning schedule is recommended.
Do not use abrasive materials on the metal electrodes. Clean with soft cloth and mild detergent only.
Use a cotton swab and mild detergent to remove deposits on the metal electrodes at the tip of the sensor.

•
Environmental Recommendations:
When used properly, this product presents no inherent danger to the environment.
Please follow local ordinance when disposing of this or any product with electronic components.
10.2 Troubleshooting
Possible Cause
Possible Solution
Symptom
•
Frequency or Current
output is erratic.
•
•
Move the Magmeter upstream at least
10 pipe diameters from obstruction.
Clean the electrodes with soft cloth.
Do not use abrasives.
•
•
•
•
•
Magmeter installed too close to
upstream obstruction.
Magmeter electrodes are coated with
solids.
•
•
Eliminate air bubbles in the pipe.
Remove the Magmeter and reinstall
with the flow direction arrow on the
sensor body pointed DOWNSTREAM.
Modify grounding as required
to protect the Magmeter from
interference.
Magmeter electrodes exposed to air
bubbles/pockets.
Electrical noise is interfering with the
measurement.
•
•
New sensor, metal surface not
properly conditioned.
Soak sensor overnight in fluid.
•
•
Soak sensor overnight in fluid.
Configure pipe so electrodes are
always in fluid.
Modify grounding as required
to protect the Magmeter from
interference.
Set low flow cutoff higher.
Return to factory for service.
•
•
•
Electrode not adequately conditioned.
Pipe is empty, Magmeter is not in fluid.
Electrical noise is interfering with the
measurement.
•
•
Output is not 0 when flow is stopped.
•
•
Defective Magmeter
•
•
•
•
4-20 mA is not scaled same as Loop
device.
•
Respan Loop device to match
Magmeter.
Set Range Jumper correctly.
Return to factory for service.
4-20 mA output is incorrect.
Loop device is not scaled same as
Magmeter.
•
•
•
•
Range Jumper not placed correctly.
Defective Magmeter
•
•
Frequency model is FMG-3001 and
FMG-3101 series.
•
•
Frequency output is inoperative
Loop output is inperative.
•
•
•
•
FMG-3000 is wrong model.
Blue jumper not in correct position.
Wiring is not correct.
Place blue jumper correctly. (Sec. 5
pg. 9)
Frequency input to other
•
•
Check wiring, make corrections.
Install 10kΩ resistor. Sec 8.1, pg. 6)
manufacturer's flow instrument does
not have pull-up resistor.
•
•
Conductivity is less than 20 µS/cm.
Electronic component failure.
•
•
Unsuitable application for Magmeter.
Return to factory for service.
•
Output is 22.1 mA.
Troubleshooting with the RED and BLUE lights
The FMG-3000 uses two colored LEDs to indicate the status of the instrument.
They are located at the top of the magmeter, inside the clear plastic cap.

No Lights:
The power is off or the sensor is not connected
The power is on but there is no flow in the pipe.
Normal operation, blink rate is proportional to the flow rate.
Empty pipe indication (electrodes are not wet.)
