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.
5. FMG-3000 Magmeter Confi guration
Whether using the FMG-3000 frequency or 4 to 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.

FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN
THE SENSOR BEING EJECTED FROM THE PIPE!
• DO NOT USE ANY TOOLS ON THE RETAINING CAP. HAND
TIGHTEN ONLY.
• LUBRICATE O-RINGS WITH A NON-PETROLEUM BASED,
VISCOUS LUBRICANT (GREASE) COMPATIBLE WITH THE
SYSTEM.
• DO NOT USE THREAD SEALANT OR LUBRICANTS ON
THE RETAINING CAP OR ON THE PLASTIC FITTING
THREADS.
• IF LEAKING IS OBSERVED FROM THE RETAINING CAP,
IT INDICATES DEFECTIVE OR WORN O-RINGS ON THE
SENSOR. DO NOT ATTEMPT TO CORRECT BY FURTHER TIGHTENING.
WARNING!
DO NOT USE thread sealant
or lubricants on the fitting threads.
Do not use any tools to
tighten the yellow retaining
cap. DO NOT USE thread
sealant orlubricants on
retaining cap!
Lubricate O-rings with a viscous
non-petroleum based lubricant
(grease) compatible with the system.

CHEMICAL COMPATIBILITY WARNING
The retaining nuts of Magmeters are not designed for prolonged contact with aggressive substances. Strong acids, caustic
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.
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.
