Description

The Signet 2551 Magmeter is an insertion-style magnetic  ow sensor. The patented sensor design is available in a variety of corrosion-

resistant materials to provide long-term reliability and minimal maintenance costs. Wetted material combinations include PP/316 SS,

PVDF/Hastelloy-C and PVDF/Titanium. The 2551 installs quickly and securely into a wide selection of  ow  ttings to deliver accurate

 ow measurement in pipe sizes ranging from DN15 to DN900 (½ in. to 36 in.).

Signet 2551 Magmeters are available with a frequency output or Digital (S

L) output for use with the Signet 5600 Batch Controller, 8900

Multi-Parameter Controller or 9900 Transmitter, or with a 4 to 20 mA output for a direct input to a PLC, SCADA or telemetry system.

All 2551 Magmeters feature empty pipe detection and LED-assisted diagnostics. The Signet 3-0250 USB to Digital (S

L) set-up tool is

available to customize every performance feature in the 2551 to adapt it to the speci c application requirements.

. Installation: Pipe ttings Georg Fischer offers a wide selection of installation ttings that control the position of the Magmeter electrodes in relation to the dimensions of the pipe. You will nd a complete list of order numbers for installation ttings in the Calibration Tables on pages 7-10. Type Description Plastic tees Type • 0.5 to 2 inch versions • MPVC or CPVC Description Iron, Carbon Steel, 316 SS Threaded tees • 0.5 to 2 in.

5. Hardware Con guration When the cover is removed the wiring from the sensor can be seen connected to the smaller terminal block. These connections should always remain connected to prevent inadvertent damage or miswiring. The terminals on the 2551 Magmeter are designed for conductors from 16 AWG to 22 AWG. WARNING! If the second conduit port is used, carefully drill the opening. (The plastic is too strong to be punched out.) The user must connect output cables to this 4-terminal block.

6. General Installation and Grounding Tips 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 will not operate properly in uids where the conductivity is less than 20 S/cm.) Grounding The 2551 Magmeter is unaffected by moderate levels of electrical noise.

8. Wiring the 3-2551-11 with Frequency or Digital (S3L) output 8.1 Wiring: Frequency output (Compatible with all POWERED Signet Flow instruments.) • When the blue jumper illustrated here is placed over both pins, the 2551-XX-11 outputs an open collector frequency signal that can be connected to any powered Signet ow meter (models 5600, 8900, 9900). • 5 VDC power is provided to the 2551 Magmeter by all Signet ow instruments. No additional power is required.

. Maintenance The 2551 Magmeter requires very little 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. 11.
