Type 2552 Magmeter Frequency or Digital (S³L) output

The Signet 2552 Metal Magmeter from Georg Fischer features all-stainless steel construction. The PVDF nosepiece and FKM O-rings are the only other wetted materials. The 2552 installs quickly into standard ISO 7- R 1 ¼ or ISO 7- R 1 ½ (1¼ in. or 1½ in. NPT) pipe outlets, and is adjustable to fit pipes from DN50 to DN2550 (2 to 102 inches). Two sensor lengths allow maximum flexibility to accommodate a variety of hardware configurations, including ball valves for hot-tap installations.

When equipped with the frequency output, the 2552 is compatible with any Signet flow instrument, while the Digital (S3L) 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 3-0250 USB to Digital (S3L) Configuration/Diagnostic Tool is available to customise every performance feature in the 2552 so it can be adapted to the user’s application requirements.
