SAFETY INSTRUCTIONS 1. Depressurize and vent system prior to installation or removal. 2. Confirm chemical compatibility before use. 3. Do not exceed maximum temperature/pressure specifications. 4. Wear safety goggles or face shield during installation/service. 5. Do not alter product construction. 6. Disconnect power before attempting any service or wiring. 2. Specifications Power Requirements • 4 to 20 mA: • • 21.6 to 26.4 VDC, 22.1 mA maximum 400 mV p-p maximum ripple voltage Frequency: 4.5 to 26.
3. Installation: Pipe fittings Omega offers a wide selection of installation fittings that control the position of the Magmeter electrodes in relation to the dimensions of the pipe. You will find a complete list of order numbers for installation fittings in the Calibration tables on pages 9-13. Type Description Type Description Plastic tees 0.5 to 4 inch versions PVC or CPVC Iron, Carbon Steel, 316 SS Threaded tees 0.5 to 2 in.
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.
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.
. 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. 10.1.
