1. Description
The latest in bipolar pulsed DC technology and the best features of an insertion sensor are packed into the +GF+ SIGNET 2550
Insertion Magmeter. Simple installation, easy maintenance, and state-of-the-art microprocessor technology make the 2550 the best
alternative to traditional full-line magmeters. The 2550 is based on the Faraday principle, and provides current frequency output signals
proportional to the flow rate. The system incorporates automatic temperature compensation, resulting in outputs that are accurate
within ±2% of actual flow rate. The bipolar electronic design and the 10000 MΩinput impedance reduce galvanic formation on the
electrodes and minimize coating problems. The isolated current output provides an universal signal to recorders, valves, process
control and data acquisition devices. The open collector frequency output is compatible with all powered flow controllers.

3. Installation
The linearity and accuracy of the 2550 depend on precise
alignment and insertion depth of the sensor in the pipe and
accurate measurement of the pipe dimensions. The installation
tool (3-2550.355) is recommended for best results.
3.1 Sensor location
Select a location for the sensor where the flow profile is fully
developed and not affected by any disturbances. A minimum of
10 pipe diameters of straight run upstream and 5 diameters
downstream is recommended. Some situations may require 20
pipe diameters or more upstream to insure a fully developed
turbulent flow profile.
The 2550 is sensitive to air bubbles at the electrodes. If there is
any question that the pipe is absolutely full, mount the sensor at
a 45°to 135°angle. The magmeter requires a clearance of
approximately 16 in./400 mm for removal.
3.2 Preparing the pipe
1. Cut a 2.125 in. ±1/16 in. (54 mm ±1.6 mm) opening in the
pipe. Carefully debur the hole for best results.
2. Install a standard 2 in. saddle or weld-on fitting on the
pipe. Welded fittings should be installed by qualified
personnel. The threads must be perpendicular to the pipe
within 1°for proper performance.

3.3 Sensor Installation with tool
WARNING: Do not remove safety ring or adjustment nut
from sensor.
The installation tool (3-2550.355) simplifies installation and
insures proper insertion depth for maximum accuracy.
1. Set installation tool angle plate (1A) on pipe next to fitting.
Insert adjusting slide (1B) into top of angle plate.
2. Place height gauge (2A) short end inside pipe and pull up
against inside diameter of pipe. Insert height gauge long
end into slot in adjusting slide. Tighten wing nut (2B) to hold
adjusting slide in place against angle plate. Remove height
gauge from pipe.

3.4 Sensor Installation Without Tool
It is recommended that the installation tool always be used when
installing the 2550. If the installation tool is not available, follow
the instructions below. Pay careful attention to the insertion depth
of the sensor in the pipe and the alignment of the electrodes
relative to the pipe.
1. Loosen three bolts at top of 2550 adjustment nut. Wrap
adjustment nut threads with 3 full wraps of sealing tape and
insert 2550 sensor into fitting. Be sure cable ports are
pointing downstream. Thread adjustment nut securely into
pipe.
2. Adjust meter height so tip of sensor is 0.20 inches below the
inside diameter of pipe. Calculate the "H" dimension:
H = sensor length - 0.2 in. - wall = 8.1025 in.
- 0.2 in - wall
H = 7.9025 - wall (H = 200 mm - wall thickness)
3. Align the magmeter parallel with the pipe ±1°. Retighten the
three 3/16 in. bolts to secure the sensor in the pipe.

4.1 Grounding Requirements
The 2550, like all magnetic flow sensors, is sensitive to electrical
noise which is present in most piping systems. The grounding
procedure illustrated below is necessary in all installations to
insure proper performance.
Connect a local earth ground to the TS5 terminal strip as
illustrated (EG1). If the cable from power source to the 2550 is
less than 200 ft./61m, EG2 is an acceptable alternative. Using
both EG1 and EG2 is always the best system.
4.2 Installation tips
1. Make sure the Filter function is set to the proper value for
your AC power source (50 or 60 Hz). (See section 5.4.4.)
2. Allow the magmeter to operate for a period before
attempting to calibrate the unit. The electronics require a
"settling" period during which the electrode may generate
unstable signals. Thirty minutes to one hour is sufficient.

Careful cable routing and sealed ports can help
prevent water intrusion.
3. In plastic piping systems, the fluid carries significant levels
of static electricity that must be grounded for best magmeter
performance.
Since plastic pipe is not grounded as metal pipes are, extra
steps must be taken. Identify the places where the fluid is in
electrical contact with external metal structures or grounds.
Connect these points to TS5 wherever practical.
4. Connect the 24 VDC power and the analog output signal
cables through separate cable ports. If the frequency output
is being used, install a watertight cable connector in one of
the unused ports. Do not run two cables through one port.
Doing so will defeat the watertight integrity of the port.

5.4 PerformanceFunctions
The next five main menu functions help to tailor the magmeter
signals to your specific environment.
5.4.1 Sensitivity
The sensitivity function limits the amount of reference level noise
detected by the Magmeter input circuit. Use the StdE display
(section 5.5.2) to evaluate the amount of reference noise in your
system. If StdE is greater than 0.05, decreasing the sensitivity
value may stabilize flow readings.
The range selections are from 1 to 10, with 1 representing the
most sensitive and 10 the least sensitive.
To change the sensitivity setting, first enter the access code
(section 5.2.1) then press the down arrow until the display shows:

5.4.2 Response Time
The response time function varies the rate at which the output
functions adjust to changes in the input signal. For example, if
the response time is set at 10 seconds, the current output will
take 10 seconds to reflect 95% of any change in flow signal input.
Use the response time to reduce the effects of turbulence and
steady/periodic noise in the flow. The standard flow deviation
display (section 5.5.2) will help evaluate the need for increased
response time. The options available are Instantaneous, 5, 10,
15, 20, 30, 40, 60, or 80 seconds.
To change the response time setting, first enter the access code
(section 5.2.1) then press the down arrow until the display shows:
The factory default setting
for response is 10 seconds.

2550. This function allows you
to compensate for viscosity.

5.5.2 Diagnostic displays
The diagnostic displays are used to evaluate abnormalities in the
process stream.
•The standard electrical deviation (StdE) is related to the level
of electrical fluctuation in the input signal reference. The
value is displayed in terms of volts, ie "0.02" represents 20
millivolts. Nominal values range from 50 mV at low velocities
to 80 mV at maximum velocity. Higher values indicate
excessive fluid noise levels, or inadequate earth ground.
Use the Sensitivity adjustment (section 5.4.1) to compensate
and check the grounding requirements (section 3.2).
•The standard flow deviation (StdF) is an overall indication of
the stability of the flow signal. It incorporates the StdE, as

RUN
EDIT
ENTER
well as mechanical factors such as unstable flow profiles,
misaligned sensors, and coated electrodes. StdF is
displayed as a percentage of flow rate, typically from 5 to 8%.
StdF levels in excess of 10% indicate inadequate installation
or application standards.
If StdE value is high, the StdF will always be high.
If StdE is low but StdF is high, look for causes related to sensor
location, such as insufficient upstream straight runs and sensor
alignment. If the StdF cannot be corrected by modifying the
installation, the Response function (section 5.4.2) will help to
smooth the output signals.
Code entry is not necessary to change the display setting.
