The Signet 2552 Metal Magmeter from Georg Fischer features all-stainless steel construction. The PVDF nosepiece and FPM O-rings are the only other wetted materials.

The 2552 installs quickly into standard 1¼ in. or 1½ in. pipe outlets, and is adjustable to

t pipes from DN50 to DN2550 (2 to 102 inches). Two sensor lengths allow maximum exibility to accommodate a variety of hardware congurations, including ball valves for

hot-tap installations.

When equipped with the frequency output, the 2552 is compatible with any Signet ow

instrument, while the S3L Digital output enables multi-channel compatibility with the

Signet 8900 Multi-Parameter Flow Controller. Select the blind 4 to 20 mA current output to interface directly with dataloggers, PLCs or telemetry systems.

Key features include Empty Pipe Detection, LED-assisted troubleshooting, and Bi-

Directional span capability (in 4 to 20 mA models).

The Signet 3-0252 Conguration Tool is available to customize every performance feature

in the 2552 so it can be adapted to the user's application requirements.

• The 2552 requires a fully developed turbulent ow prole for accurate measurement. Selecting the correct location in the

piping system is critical to the performance of the magmeter.

• Locate the magmeter where air bubbles will not contact the electrodes.

• Placing the sensor in a vertical section of pipe, with ow going UPHILL is the rst choice for this requirement.

• The piping system should be designed to keep the sensor wet at all times.

• In applications where the conductivity of the process liquid is less than 100 μS, magmeters should be allowed to soak in a full

pipe for 24 hours before operation.

General Installation

Air pockets and bubbles will travel at the top of a horizontal pipe, so avoid vertical installations.

20 x ID

Located the magmeter in a

"trap" to prevent air bubbles

and to keep the electrodes wetted for best performance.

Vertical Installation

+GF+

Recommended Installation

Sediments and debris that collect at the

bottom of a horizontal

pipe will interference with the operation.

Locating the sensor where the ow is upward protects the sensor from exposure to air bubbles and may offset upstream turbulence

caused by pipe conditions and other hardware.

Horizontal Installation

If the magmeter must be mounted

in a horizontal section of pipe, take extra precautions to prevent air bubbles from passing over the

sensor.

Select a location with suf cient

distance of straight pipe immediately upstream of the sensor. The dimensions illustrated here are intended for general guidance.

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  uids may require a longer conditioning period.

• The Magmeter may not operate properly in  uids where the conductivity is less than 20 µS/cm.

Grounding

The 2552 Magmeter is unaffected by moderate levels

of electrical noise, especially if installed in a properly

grounded metal piping system. However, in some

applications it may be necessary to ground portions of the system to eliminate electrical interference. The

grounding requirements will vary with each installation.

One or more of the following steps may be applied if the

2552 Magmeter is affected by electrical noise:

 Connect a wire (14 AWG/2.08 mm

from the ground terminal screw on the sensor nut directly to a local Earth ground.

recommended)

See page 9 for wiring details.

 Install  uid grounding devices immediately upstream

and downstream of the Magmeter.

Connect the  uid grounds to the Earth ground

terminal on the 2552.

Use  anged grounding rings or metal electrodes on

plastic pipes, or metal clamps on metal pipes.

Fluid grounds must be in direct contact with the  uid,

and as near to the Magmeter as possible.

 Connect the SHIELD conductor to Earth ground

near the instrument.

Preparing for Installation

The alignment of the electrodes in the pipe and the insertion depth of the electrodes in relation to the inside diameter of the pipe are critical to the successful operation and calibration of the system. The brass rod that is supplied with the 2552 is used to assist with this requirement.

H-Dimension

The H-dimension is the distance from the TOP OF THE PIPE to the BOTTOM OF THE BRASS ROD.

The tables on pages 11-12 include the H-dimension for two of the most common pipe schedules from DN50 to DN2550 (2 in. to 102 in.). If the pipe is not represented in the tables on pages 11-12, use the procedure below to determine the H-dimension.

The goal of the procedure is to place the Magmeter electrodes 10% inside of the pipe

1. The height from the magmeter electrodes to the alignment rod is:

-2 Versions: 276.3 mm ( 10.88 in. )

-3 Versions: 419.0 mm ( 16.50 in. )

2. Subtract the wall thickness of the pipe:

- Wall Thickness: -_____ mm ( ______ in.)

3. Subtract 10% of the pipe inside diameter:

- 10% of pipe id: -_____ mm ( ______ in.)

4. The result is the H-dimension. Record the result here for reference at the installation site:

= H dimension: =_____ mm ( ______ in.)

H Dimension

Hardware stack height is important

The H-dimension represents the total height

available for the installation hardware.

Hardware

If there is insufcient clearance to accommodate

the hardware, select a longer 2552 Magmeter or modify the hardware to reduce the stack height.

The following items are required to properly install the Magmeter:

Supplied with 2552 Magmeter:

• Ruler

• Brass alignment rod

• H-dimension value for your pipe

(See pages 6)

• Hex wrench

• 2 clamp rings

• Grounding screw

• Anti-Seize Lubricant for stainless steel

Not supplied with the 2552 Magmeter:

• Female pipe tting (weld-on or saddle) with:

• 1¼ in. NPT or ISO 7/Rc 1¼ threads (2552-2)

• 1½ in. NPT or ISO 7/Rc 1½ threads (2552-3)

• 32 mm (1¼ in.) or 40 mm (1½ in.) ball valve (for hot tap installations)

• 32 mm (1¼ in.) or 40 mm (1½ in.) diameter drill

• 32 mm (1¼ in.) pipe nipple

• Pipe thread sealant suitable for application

• Pipe wrench

1. Determine the H-dimension for the pipe

• The tables on pages 11-12 list the H-dimension metal pipe per ANSI 36.10 and ANSI 36.19.

• Use the procedure on page 6 to determine the H-dimension for other types of pipe.

2. Prepare the pipe

a. Cut a 32 mm (1¼ in.) opening in the pipe. b. Install a 32 mm (1¼ in.) for 2552-2, or 40 mm (1½ in.) for 2552-3 outlet onto the pipe.

This tting must withstand pressures up to 20 bar (300 psi).

For Hot-tap installations:

• Thread a matching pipe nipple and ball valve into the outlet.

• Use a suitable paste or sealing tape to provide a leakproof connection.

Hot- tap drilling requires special tools and skills.

This task should only be performed by qualied personnel.

For Ball Valve installations:

Position the ball valve handle so it is parallel to the pipe.

This will prevent the valve handle from interfering with the

adjustment and alignment of the magmeter.

Remember to tilt the magmeter to avoid air bubbles

(see General Installation, page 4).

3. Install the Magmeter into the pipe

a. Apply sealing tape or paste to the male threads of the process

connector nut.

b. Tighten the process connector into the pipe.

• Do not damage the locking set screw when using tools.

• The sensor is marked to identify the downstream alignment.

The arrow MUST point DOWNSTREAM.

• Hold the outer sensor housing securely while threading the

process connector nut into the tting. This will prevent the cable

from becoming twisted around the sensor while the process connector is tightened into the pipe.

c. Loosen the set screw in the process connector nut.

d. Rotate the Acme threaded outer housing until the ow arrow is

aligned in the proper direction.

e. Secure the set screw sufciently to prevent the outer housing

from spinning.

Do not tighten the set screw yet. It may require additional adjustment.

4 to 20 mA Loop Output Wiring

Wiring the 2552-XX-12 Magmeter with 4 to 20 mA Loop Output

The 2552 Magmeter is a traditional 2-wire passive 4 to 20 mA

loop transmitter.

• External loop power (21.6 to 26.4 VDC, 22.1 mA maximum) is required. (See Power Requirements

on pg. 2)

The maximum loop resistance the Magmeter can

accomodate is 300 Ω.

The cable length from the Magmeter to the loop

monitor cannot exceed 300 m (1000 ft).

• All 2552 Magmeters are shipped from the factory with the 4 to 20 mA output scaled for 0 to 5 m/s (0 to 16.4 ft/s).

If this operating range is suitable, no adjustments are necessary. The calibration charts in this manual list the

20 mA setpoint for each pipe size. Use this information to program the 4 to 20 mA range of the loop device (PLC, Datalogger, recorder, etc.).

Technical Support Information

Bi-Directional Flow

The 2552 magmeter is designed to measure bi-directional ow.

• 4 to 20 mA output models: May be scaled to span any

ow range:

For example: "4 to 20 mA = -100 GPM to +100 GPM"

• Frequency output models: The 2552 will generate

a frequency regardless of ow direction. Signet instrumentation cannot distinguish bi-directional ow from

frequency inputs.

FLOW→

• Digital (S

L) output models: Reverse ow results in 0

ow rate displayed on the 8900 Multi-Parameter Controller.

• The forward ow direction is indicated at the base of the sensor. The arrow must point DOWNSTREAM.

0252 Conguration Tool

No calibration is necessary to begin using the 2552.

The application and performance settings are selected by the factory to meet the requirements of most applications.

The 2552 application and performance settings can be customized using the 3-0252 Conguration Tool.

The following parameters can be modied with the 3-0252 USB Setup tool and software. A Windows PC is required:

• 4 to 20 mA span: Factory setting is 0 to 5 m/s.

Can be customized to any range, including bi-directional ow ranges, ±10 m/s maximum.

• Noise Rejection Filter: Factory set for 60 Hz.

Can be changed to 50 Hz.

• Low Flow Cutoff: Factory setting is 0.05 m/s.

Can be increased to meet specic application requirements.

• Averaging Time:Factory setting is 14 seconds

Can be customized from 0.1 seconds to 100 seconds

• Sensitivity: Factory setting is 25% of full scale

Can be customized to any % of full scale

MONITOR/VERIFY SENSOR

The MONITOR/VERIFY SENSOR function in the Signet

3-0252 Setup Tool software is very useful as a system

troubleshooting tool.

Troubleshooting

Troubleshooting with the RED and BLUE lights

The 2552 uses two colored LEDs to indicate the status of the measurement. They are located at the top of the magmeter, recessed inside the threaded steel housing. Look down the outer housing to see them.

No Lights: The power is off or the sensor is not connected Solid Blue: The power is on but there is no ow in the pipe. Blinking Blue: Normal operation, blink rate is proportional to the ow rate. Alternating Red-Blue: Empty pipe indication (electrodes are not wet.) Blinking Red: System errors (Generally indicates electrical noise interference) Solid Red: Instrument error (Generally indicates defective electronics component)

The lights are for troubleshooting guidance only and are not absolute fault indicators.

Maintenance

There are no user-serviceable components in the Magmeter.

• If the uid 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.

• If the sensor nut will not turn smoothly, a light lubricant can be applied to the threads.

• Re-apply Anti-Seize Lubricant for stainless steel ("Permatex" brand or equivalent) to the acme threads whenever servicing and

before retracting sensor.

Dimension

Sensor Selection Guide

The 2552 Magmeter can be installed into a variety of pipe sizes. Follow the steps below to ensure that you choose the right sensor for your application.

Step 1: Determine how the sensor will be installed

A. For standard (non Hot-Tap) installations: The height of the weldolet (threadolet) and pipe adapter(s) should be determined before the sen-

sor is purchased.

• For retrot installations, the stack height, or “A” dimension (see Fig. 1), is the overall height from the top of the pipe to

the highest point of the stack before the sensor is connected.

• For new installations, Signet recommends

a weldolet (threadolet) and an adapter to accommodate the 1¼ in. (or 1½ in. for 2552-3) sensor process threads. The stack height, or “A” dimension (see Fig. 1), is the overall height from the top of the pipe to the

highest point of the stack.

B. For Hot-Tap installations: The stack height of the ball valve, nipple weldolet (threadolet) and pipe adapters should be determined before the sensor is purchased.

• For retrot installations, the ball valve must be at least a 1¼ in. (or 1½ in. for 2552-3) full port valve. The stack height, or “A” dimension (see Fig. 2), is the overall height

from the top of the pipe to the top of the ball

valve, or the top of the highest point of the

• For new installations, Signet recommends

a 1¼ in. or 1½ in. full port ball valve, a short nipple and a weldolet (threadolet). The stack height or “A” dimension (see Fig. 2) is the overall height from the top of the pipe to the top of the ball valve.

stack before the sensor is connected.

Step 2: Determine how the sensor will be installed

Once the “A” dimension is determined, go to the sensor selection table and nd your “A” dimension on the left column. Next, nd the appropriate pipe size at the top of the chart. To determine the correct sensor size locate where the pipe size column meets the max “A” dimension row.
