GF Signet 2552 - User Manual

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 S
3
L 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.
