4. Selecting a Location

• The FMG-3000 requires a full pipe and a fully developed turbulent fl ow profi le 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.

• Chemical injection systems can temporarily alter the fl uid conductivity and cause
anomalies in the magmeter measurement.

To avoid this problem, install the Magmeter UPSTREAM of the injection point.

Select a location with suffi cient distance of
straight pipe immediately upstream of the
sensor.

Locating the sensor in a trap or where the fl ow
is upward helps to protect the sensor from
exposure to air bubbles when the system is in
operation.

These confi gurations are not recommended
because it is diffi cult to keep the pipe full.

In a gravity-fl ow 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.

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.

WARNING!

If the second conduit port is used, carefully drill the
opening.

(The plastic is too strong to be punched out.)

• Secure the Magmeter in a vise to prevent damage or injury.

• The plastic inside the port is very thin. Do not allow the drill to
penetrate too deeply and damage the Magmeter wiring.

Important:

• The directional arrow on the body of the sensor must be pointed DOWNSTREAM
for correct operation.

• The FLOW arrow decal can be placed directly on the pipe to identify the direction of fl ow.

• 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.

substances and solvents or their vapor may lead to failure of the retaining nut, ejection of the sensor and loss of the process fl uid
with possibly serious consequences, such as damage to equipment and serious personal injury. Retaining nuts that may have been
in contact with such substances, e.g. due to leakage or spilling, must be replaced.

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 fl uids may require a longer conditioning period. The Magmeter may not operate properly in fl uids 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:

 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 mm
recommended) from this terminal directly to
a local Earth ground.

Instrument

2

 Install fl uid grounding devices immediately upstream and

downstream of the Magmeter.

Connect the fl uid grounds to the Earth ground terminal on the

FMG-3000.

Use fl anged grounding rings or metal electrodes on plastic pipes,

or metal clamps on metal pipes.

Fluid grounds must be in direct contact with the fl uid, and as

near to the Magmeter as possible.

 The shield from the output cable must be terminated at the

remote instrument ONLY.

This shield must not be connected at both ends!

7. Wiring the FMG-3002, 3102 and 3202 Magmeter with 4 to 20 mA Loop Output

The FMG-3002, 3102 and 3202 Magmeters are traditional 2-wire passive 4 to 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, 3102 and 3202 Magmeters are shipped from the factory with the 4 to 20 mA output scaled for 0 to 5 m/s (0 to

16.4 ft/s). The Calibration charts on pages 8-12 list the 20 mA setpoint for each installation fi tting. Use this information to program
the 4 to 20 mA range of the loop device (PLC, Datalogger, recorder, etc.)

10. Maintenance

The FMG-3000 series Magmeter requires very little maintenance. There are no user-serviceable components in the Magmeter.

• If the fl uid 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.

10.1. 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

Symptom Possible Cause Solution

Relocate the magmeter to have straight
uninterrupted pipe upstream of the sensor for
at least 10 x the pipe diameter.

Eliminate air bubbles in the pipe.

Remove the magmeter and reinstall with
the fl ow direction arrow on the sensor body
pointed DOWNSTREAM.

Review the grounding of the magmeter and
the pipe. Install adequate Earth ground to
allow the Magmeter to operate properly.

Soak sensor overnight in fl uid.

Increase the Low Flow Cutoff.

Modify grounding to protect the Magmeter
from interference.

Install 10 kΩ resistor. (page 8)

Unsuitable application for Magmeter.

Output is erratic and unstable.

Output is not 0 when fl ow is stopped.

4 to 20 mA output is incorrect.

Frequency output is inoperative
Loop output is inoperative.

Output is 22.1 mA

Magmeter installed too close to upstream
obstruction.

Magmeter located in area exposed to air
bubbles/pockets.

Magmeter is installed in pipe backwards.

Electrical noise is interfering with the
measurement.

Electrodes are coated with solids. Carefully clean the electrodes.

New sensor; metal surface not properly
conditioned.

Electrodes not adequately conditioned. Soak sensor overnight in fl uid.

Vibration or other movement in pipe causes
magmeter to detect fl ow.

Electrical noise interference

Defective Magmeter Return to factory for service.

4 to 20 mA is not scaled same as Loop device. Respan Loop device to match Magmeter.

Range Jumper not placed correctly. Set Range Jumper correctly.

Defective Magmeter Return to factory for service

Blue jumper not in correct position Place blue jumper correctly. (page 6)

Wiring is not correct. Check wiring, make corrections.

Frequency input to other manufacturer's fl ow
instrument does not have pull-up resistor.

Conductivity is less than 20 μS/cm (The fl uid is
too clean for Magmeter.)

Electronic component failure. Return Magmeter to factory.

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
Solid Blue (D7): The power is on, the pipe is full, but there is no fl ow in the pipe.
Blinking Blue (D7): Normal operation, blink rate is proportional to the fl ow rate.
Alternating Red-Blue: Empty pipe indication (electrodes are not wet.)
Blinking Red (D6): System errors (Electrical noise interference)
Solid Red (D6): Instrument error (defective electronics component)
