3.1 Selecting a Location

• The magmeter 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.

3.2 Empty Pipe Detection

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.

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

5.5 Wiring Relays

Relay 1, Relay 2 Type: Mechanical SPDT Rating: 5A @ 30 VDC max., 5 A @ 250 VAC max

Relays 1 and 2 are dry contact relays rated for 5 A maximum current. Relays 1 and 2 are best suited for switching high voltage loads, such as AC powered pumps and valves.

When used to switch inductive loads, dry contact relays may be damaged by arcing. Omega recommends the installation of a ﬁ lter device to prevent such damage.

FP90RC RC Filter kit (for relay use)

Relay 3 Type: Solid State Rating: 50 mA @ 30 VDC, 50 mA @ 42 VAC

Relay 3 is a solid state relay. It can be applied exactly the same as a dry contact relay, but the current rating is 0.2 A (200 mA) maximum. Relay 3 is best suited to pulse applications and low voltage loads.

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.

Sensitivity: Set a percentage of maximum range by which the ﬂ ow must change to override

the averaging feature and "jump" quickly to the new ﬂ ow rate. See detailed explanation in section 7.1.

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.

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 to 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.

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.

At START, the magmeter begins counting the ﬂ ow past the sensor.

At STOP, the magmeter stores the total ﬂ ow accumulated since the START.

Enter the VOLUME that has been pumped past the sensor.

This error message appears if volume entered or the accumulated ﬂ ow is zero. Repeat the test after checking the system.

This message appears if the new K-Factor is less than 0.0001 or greater than 999999. To correct the problem, perform the volumetric ﬂ ow again, and be certain that the volume entered is accurate. Using the information from the VOLUME method, the magmeter will recalculate a new K-Factor. Press ENTER to accept the new value, or use the keypad to adjust the value.

8.2 Rate Method Of Calibration

Use this method if the magmeter must be calibrated to match a reference ﬂ ow meter. This is the method most commonly used by monitoring agencies, and for large pipes where volumetric calibration is impractical. The accuracy of this calibration method is largely dependent on the accuracy of the reference meter and the proximity of the reference to the magmeter.

Program a relay to activate when the Resettable Totalizer reaches a speciﬁ c value. The maximum setting is 999999.

Application example: A ﬁ lter must be replaced in a reverse osmosis 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.

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.

Example: If the delay is set to 5 seconds, in the example above the relay will not be activated until the ﬂ ow rate exceeds 100 GPM for 5 seconds.

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

Do not terminate shield at Magmeter

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

Instrument

from water intrusion.

• Use Teﬂ on tape or a suitable sealant on cable ports.

• The magmeter must be carefully grounded to eliminate electrical noise

Sensor Grounding ring

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

4 in. to 50 in.

(10 cm to 1.3 m)

4 in. to 50 in.

(10 cm to 1.3 m)

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.

Grounding rings on plastic pipe

(Install between flanges)

metal straps on metal pipe

2. 2.

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

) 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.
