Important:
• 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 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 4-20 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.
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.
