Description
Signet 2552 Metal Magmeter Flow Sensor 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 1¼ in. or 1½ in. pipe outlets, and is adjustable to fit pipes from DN50 to DN2550 (2 to 102 in.). 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 externally powered Signet flow instrument, while the digital (S3L) output enables multi-channel compatibility with Signet 8900, 9900 or 9950 Multi-Parameter instruments. Select the blind 4 to 20 mA current output to interface directly with data loggers, 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 Configuration Tool is available to customize every performance feature in the 2552 so it can be adapted to the user’s application requirements.

Ordering Notes
- 1) Sensor insertion depth is the distance from the bottom of the sensor housing to the tip of the sensor.
- 2) Hot-Tap installations require a 1¼ in. or 1½ in. ball valve.
- 3) See Sensor Selection Guide on previous page to determine the sensor length required.
