The GF 2581 FlowtraMag is a full-bore plastic PVC in-line style magnetic fl owmeter. The
PVC body with Titanium or Hastelloy
three times lighter in weight compared to traditional metal magmeters on the market. It is
designed for high accuracy fl ow measurement in short pipe runs, making it an ideal solution
for industrial applications where performance and ease of use are important.
The FlowtraMag is available in pipe sizes of DN25 (1 in.), DN40 (1.5 in.), DN50 (2 in.),
DN80 (3 in.) and DN100 (4 in.), optimized for performance in short pipe runs often
associated with fi nal effl uent lines, well heads and water treatment skids.

Georg Fischer products are manufactured in a variety of wetted
materials to suit various liquids and chemicals.
All plastic materials including typical piping types (PVC) are more
or less permeable to contained media, such as water or volatile
substances, including some acids. This eff ect is not related to
porosity, but purely a matter of gas diff usion through the plastic.
If the plastic material is compatible with the medium according
to the application guidelines, the permeation will not damage
the plastic itself. However, if the plastic encloses other sensitive
components, as is the case with GF FlowtraMag meter, these
may be aff ected or damaged by the media diff using through the
plastic body.
Unit is factory shipped confi gured to measure water.

Vertical Pipe Runs
To ensure pipe is fl owing full with some back pressure, it is highly recommended that the fl uid fl ows upward.
Gravity and Discharge Lines
It is recommended to install a u-trap to ensure the pipe remains full at all times and to minimize air bubbles.
A vacuum breaker may be required downstream of the FlowtraMag to ensure pipe doesn't drain and fi ll with air.

Vertical flow is OK IF the
pipe remains FULL
at all times.

Electromagnetic Compatibility (EMC) Recommendations
Complex instrumentation systems such as the 2581 FlowtraMag and the associated devices may face challenges involving
Electromagnetic Interference (EMI). EMI interference may be coupled to the system via cables (conducted interference) or
broadcast via electrical radiation (radiated interference).
Radiated interference may be mitigated by relocating the source or increasing the distance from the source.
Metal shielding may be used.

(EMC enhancement)
S3L / Frequency
4 to 20 mA
Conducted interference can be mitigated by careful wiring practices. Because EMI may follow multiple paths, it will be necessary
to observe the eff ectiveness of various grounding options.
2581 FlowtraMag Power Cable
• In electrically noisy environments, connect the power cable shield (drain) wire to a clean low impedance earth ground.
• If there is a single power supply for all 2581 FlowtraMag system components (Instruments, PLCs and VFDs), route signal
wiring directly to the instruments. Do not use ground points common to other wiring. Avoid creating ground loops.
• If separate power supplies are used, connect all power grounds to a common low impedance ground.
2581 FlowtraMag Output Cable
• In electrically noisy environments, connecting the Signal Output cable shield (drain) wire to a clean low impedance earth
ground may help reduce signal noise and preserve communication. Observe the diff erence between connecting or not
connecting the shield. Avoid creating ground loops.
Frequency/S
- The S
for the 2581 FlowtraMag and the monitoring fl ow instrument.
4 to 20 mA Output
- If the 4 to 20 mA is used to control a highly inductive load such as a Variable Freq Drive or a DC motor, use separate
DC power supplies for the 2581 FlowtraMag and the 4 to 20 mA device, active mode should be used.
- In Passive mode the 2581 FlowtraMag loop output cable shares the ground with the 2581 FlowtraMag Power Supply.
Use the same DC power supply for the 2581 FlowtraMag and the 4 to 20 mA device.
- In Active mode the 2581 FlowtraMag loop output cable is isolated from the 2581 FlowtraMag Power Supply.
The 4 to 20 mA receiving device can use a diff erent Power Supply.

Wiring Confi guration Continued
Recommended:
The directional arrow should be pointed
DOWNSTREAM for correct operation. If the 2581
FlowtraMag is installed on a vertical pipe, the cable
ports should be turned to point downward.
This will prevent condensation from being
channeled into the enclosure.

AVERAGING and SENSITIVITY
Averaging and Sensitivity Settings
• Because ideal fl ow conditions are often impossible to achieve, the fl uids fl ow is often erratic, which causes erratic readings in
control features (e.g., relays, 4 to 20 mA loops, etc.) that are associated with the fl ow rate.
• The best solution to these problems is to correct any piping defi ciency that causes the instability. This may involve longer
straight runs upstream, taking steps to ensure pipe remains full during fl ow conditions, and other installation changes.
In many situations, however, these measures are simply not possible.
• The 2581 FlowtraMag provides two tools that are designed to "work around" these defi ciencies. The Averaging and the
Sensitivity features should be studied before making adjustments.
Averaging Time in Seconds (Factory set: Low)
• Set the time the meter will use as the averaging period. The ranges are Off , Low (10 s), Med (40 s) and High (120 s).
Use higher averaging times to smooth the display and current output where the fl ow in the pipe is erratic.
Quick Response Sensitivity (Factory Set: 0.5 m/s (1.64 ft/s) equivalent)
• Sets an amount of fl ow rate change at a given reference fl ow rate required to momentarily allow the 2581 FlowtraMag to change
from the selected averaging time to a faster response. The reference fl ow rate should be near the range of normal operation.
Turn the averaging setting to off and observe the fl ow rate variation, enter a sensitivity amount that is two times larger than the
amount of fl ow variation.
With AVERAGING set to Off and with SENSITIVITY set to zero, the
2581 FlowtraMag responds to every unstable shift in the fl ow.
The dashed red line represents the actual output of the fl ow sensor
in unstable fl ow conditions.
With AVERAGING set to Medium and SENSITIVITY still set to zero
the fl ow rate is stabilized, but a sharp change in fl ow rate is not
represented for 50 seconds or longer (dotted green line).
With AVERAGING at Medium and SENSITIVITY set to a moderate
amount, the fl ow rate is stabilized, while the sudden shift in fl ow is
refl ected very quickly (solid blue line).
NOTE: The SENSITIVITY function is ineff ective if the AVERAGING function is set to off (seconds).
LED Status Indicators
LEDs on the 2581 FlowtraMag circuit board are useful to identify problems with the meter and the fl ow conditions.
LED Condition Indication
All Off The power is off or the sensor is not connected
Solid Blue Normal operation, full pipe, no fl ow
Blinking Blue Normal operation, blink rate is proportional to fl ow rate
Solid Purple Partially fi lled pipe, fl ow rate is zero
