3.1 Location of Fitting
The magmeter can only measure fl ow if the pipe is full. If the piping system has entrained air pockets, take steps to locate the sensor so the air pockets will not contact the electrodes.

These confi gurations guarantee that the pipe is always fi lled. The sensor cannot be exposed to air bubbles.
Avoid these situations unless you are certain that the sensor will not be exposed to air bubbles.
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. If air bubbles pass across the Magmeter electrodes, the output will become erratic.

If the pipe is not full, or the electrodes are not immersed, the fl ow display will show zero and all output functions will behave accordingly.
If the magmeter electrodes are exposed to fl ow transitions and air bubbles, the measurement may be incorrect until the conditions are stabilized.

4.0 Overview of Display Magmeter
Display Magmeters use a dual-sided electronics module and dual conduit ports. Unused ports must be sealed to prevent corrosion and moisture from entering the circuitry.
1. The lower set of conduit ports provide access to the wiring terminals for:
• Loop Power
• Flow Output Signal, whether it is a current loop, a frequency or the Mirror Relay 1 output.
2. The upper set of conduit ports provide access to the wiring terminals for:
• Relay output wiring
• Auxiliary power for relay coils and display backlight
3. The sensor is marked with a directional arrow to indicate the direction identifi ed as forward fl ow. An adhesive decal is also provided that can be affi xed to the pipe to indicate the direction of forward fl ow. Flow in the opposite direction from the arrow will be identifi ed as reverse fl ow on the display by a "-" symbol.
4. The terminals in the magmeter are designed to accomodate 14 to 22 AWG conductors.
5. The display includes two LEDs that light when Relay 1 or Relay 2 are activated.
• All three relays can be monitored by scrolling to the Relay Status display located in the View
English >
menu.
• If the Language option has not been made, new magmeters will always open with the Select Language display.
6. The part number, serial number and output type are identifi ed on the electronics module.

Set 20 mA: In the FMG3002 and FMG3102 versions only, set the fl ow rate where the current output will be 20 mA.
The 4-20 mA output may be spanned to monitor forward and reverse fl ow rates.
Total Factor: Set the factor by which the totalizer will count. This setting is made in the application units (ie; gallons, liters, etc..)
Totalizer Units: Set the Totalizer Units. This setting serves as a label for the totalizer displays only. It has no effect on the measurement. The special characters listed in the Total Factor settings are available here also.
Low Flow Cutoff: Set a fl ow rate that the magmeter will use as a minimum threshhold. If the fl ow rate falls below this value, the magmeter will respond as if the fl ow were zero.
Averaging: Set the averaging period based on the installation and fl ow conditions. Smaller values allow the magmeter to respond to changes in fl ow rate quickly, while larger values smooth the fl uctuations caused by installation and fl ow conditions. See section 7.1 for details.

7.1 Averaging and Sensitivity
Even the most carefully engineered fl ow systems may experience erratic and unstable conditions. If the instability is communicated to the output functions, the results may create problems for control devices.
To alleviate these issues, the magmeter provides two adjustments that operate in tandem. The information here will help in determining the appropriate settings for any specifi c application.
Averaging
The AVERAGING setting dictates the time over which the magmeter will average the fl ow signal.
The LCD display is updated every second. With averaging at
14 seconds, the fl ow rate on the display is an average of the previous 14 seconds input.
Short averaging times provide the fastest display and output
response to changes in the fl ow rate.
Higher averaging times help to smooth the display and
current output where the fl ow in the pipe is erratic or unstable due to installation limitations.
Sensitivity
The SENSITIVITY setting determines how the magmeter responds to sudden surges in the fl ow rate. It "overrides" the Averaging function just long enough to allow an actual change in fl ow rate to be displayed, then resumes the averaging. The result is a smooth fl ow display and a quick response to large shifts in the fl ow rate.
No Averaging
With AVERAGING set to zero, the fl ow rate will be displayed immediately and with no fi ltering. This line represents the actual output of the fl ow sensor as it responds to unstable fl ow conditions in the pipe.
Velocity
Time
10 s 20 s 30 s 40 s 50 s 60 s 70 s
Averaging Only
With AVERAGING set to 50 seconds and SENSITIVITY still set to zero the fl ow rate is stabilized, but a sharp change in fl ow rate is not represented on the display or at the output for 50 seconds or longer.
Velocity
The settings for Sensitivity represent a percentage of the
magmeter's maximum range, or 10 m/s.
Example: A sensitivity setting of 25% means that the fl ow
rate must change instantly and by more than 2.5 m/s before the function is enabled.
NOTE: The SENSITIVITY function is ineffective if the Averaging function is set to zero.
CAUTION
The SENSITIVITY function changes the response characteristics of the magmeter. If used as part of a tuned closed loop control system such a change may be undesirable.
Time
10 s 20 s 30 s 40 s 50 s 60 s 70 s
Averaging and Sensitivity
With AVERAGING at 50 seconds and SENSITIVITY set to 25%, the fl ow rate is stabilized, while the sudden shift in fl ow is refl ected very quickly.

7.2 Bi-Directional Flow
The magmeter is designed to measure bi-directional fl ow.
The forward fl ow direction is indicated by the directional arrow molded into the side
Flow
of the magmeter sensor.
The conduit ports are assembled at the factory to point UPSTREAM. They may be reversed by
disassembling the components of the magmeter and reassembling.
Flow Rate Display: The "+" sign is suppressed during forward fl ow. "-123.45 GPM" during reverse fl ow.
Totalizer Display: The totalizer will count during forward fl ow conditions only. During reverse fl ow the totalizer will not increment.
Relay Outputs: May be set to detect reverse fl ow: "Low Setpoint at -25GPM."
4-20 mA output: May be scaled to span any fl ow range:
For example: "4 to 20 mA = -100 GPM to +100 GPM"
Frequency output, Frequency ÷ 10 output: Reverse fl ow is processed same as forward fl ow in the frequency output magmeters.

8.0 Calibration Menu
The K-factors published in this manual assume that the fl ow conditions in the pipe are ideal. Many factors that affect the fl ow rate are beyond the control of the magmeter; variations in actual pipe dimensions, pipe smoothness, and other fl ow conditions will contribute to the total system error.
Performing a custom calibration with the magmeter in place will adjust the K-factor and can serve to compensate for installation conditions that may be less than ideal.
Select one of the calibration methods in this menu to achieve the most accurate measurement possible in a specifi c application.

8.1 Volume method of calibration
Use the volume method of calibration if the fl uid passing the magmeter can be measured by a volumetric method (as in a vessel of known volume, or by weight). It requires the ability to pump a known volume of water past the magmeter, and then input the volume into the magmeter program. It is most useful for small pipes and lower fl ow rates. When performed properly, volumetric calibration is the most accurate method. For best results a fi ve minute test period is recommended, and the test period should be no less than two minutes.

9.0 Relay Menus
Magmeter models FMG3001 and FMG3002 have two dry contact relays (Relays 1 and 2) and one Solid State relay (Relay 3).
®
Any of these relays can be set to any of the operating modes listed below.
The setpoint values for HIGH, LOW and WINDOW modes can be set to negative values if required. For example, a LOW alarm might be set to activate if the fl ow rate falls below -10 GPM.
Negative values are not available for relays in PULSE or TOTAL modes.
Off: If a relay is not used, it can be turned Off to prevent contact
wear.
NOTE: The Security Code must be entered before modifying the relay menu.

Pulse Width: Adjust the length of time the relay will remain activated. The pulse width setting is dependent on the type of external equipment being connected to the relay.
9.2 Total Relay mode
Program a relay to activate when the Resetable totalizer reaches a specifi c value. The maximum setting is 999999.
Application example: A fi lter must be replaced in a R.O. system every 10000 gallons. The service representative that installs a new fi lter sets relay 3 to Total mode, sets the setpoint at 10000 and resets the totalizer to 000000.00. When the totalizer is reset, the relay will be deactivated and the process begins anew.
Every time the Totalizer reaches 10000, the relay activates and lights a message indicator to remind the operator to contact the service representative to replace the fi lter.

Hysteresis: Set a fl ow rate increment where the relay will be deactivated. The hysteresis setting serves to prevent relay "chatter" when the fl ow rate recovers from an alarm condition by requiring the fl ow rate to move substantially within the setpoint.
Example: If high setpoint is 100 GPM, and hysteresis is 5 GPM, the relay will be activated if fl ow rate reaches 100.1 GPM, but will only be deactivated when the fl ow rate is 95 GPM (5 GPM inside the setpoint.)
Delay: Set a time period for the relay to wait after reaching the setpoint. This delay serves to prevent the relay "chatter" by allowing the fl ow rate time to move back within the setpoint.

11.1 Output Modes
In FREQUENCY output mode, the OMEGAMAG serves as a traditional fl ow sensor and provides an output pulse that is compatible with most Omega POWERED fl ow instruments. It is not compatible with the FPM5800 Self-Powered Flow Meter or the FPM5750 series Battery-powered fl ow totalizer. The frequency output range is from 0 Hz to 1000 Hz.
The FREQUENCY ÷ 10 output mode reduces the output frequency of the OMEGAMAG to a range that is useful for some programmable logic controllers (PLC). The frequency output range is from 0 Hz to 100 Hz. This shift does not affect the stated accuracy of the magmeter's frequency output.
The MIRROR RELAY 1 output mode allows Frequency models to use the Open Collector Output like a relay that can be programmed via the Relay 1 menu. If the magmeter is equipped with relays, this mode will mirror the settings of Relay 1. If the magmeter is not equipped with relays, this mode can still be selected and programmed via the Relay 1 menu.

12.0 Technical Information
12.1 Grounding
Precalibration conditioning: The magmeter may appear to be unstable immediately after installation. Allow the sensor to sit in a full pipe for 24 hours before beginning calibration and operation.
Use a cable gland or a liquid tight connector to seal the cable ports from water intrusion.
Use Tefl on tape or a suitable sealant on cable ports.
The magmeter must be carefully grounded to eliminate electrical noise that may interfere with the measurement.
Grounding requirements will vary with each installation.
The following recommendations should be applied in sequence until the interference is eliminated.
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 conductor (14 AWG/2.08 mm2 wire recommended) from this terminal directly to Earth ground to prevent electrical noise from interfering with the magmeter signal.
If the interference persists, apply step #2:
Connect grounding rings, metal clamps or grounding electrodes to the pipe immediately upstream and downstream of the
magmeter sensor location. These devices must be in contact with the fl uid.
If the interference persists, apply step #3:
The shield from the output cable must be terminated at the remote instrument ONLY.
This shield must not be connected at both ends!
If the interference persists, apply step #4:
Connect an additional wire (minimum AWG 14/2.08 mm
2
) from the remote instrument ground to the magmeter ground terminal.

12.2 Maintenance
The OMEGAMAG 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 regimen 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.
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.
