1. Description
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 fi t pipes
from DN50 to DN2550 (2 to 102 inches). Three sensor lengths allow maximum fl exibility to accommodate a variety of hardware
confi gurations, including ball valves for hot-tap installations.
When equipped with the frequency output, the 2552 is compatible with any Signet fl 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 3-0250 USB to Digital (S
3 L) Confi guration/Diagnostic Tool is available to customize every performance feature in the 2552
so it can be adapted to the user's application requirements.
Performance
Pipe size range: DN50 to DN2550 (2 in. to 102 in.)
Flow Range:
•
Minimum: 0.05 m/s (0.15 ft/s)
• Maximum: 10 m/s (33 ft/s) for pipes to DN 1200 (48 in.)
3 m/s (10 ft./s) for pipes over DN 1200 (48 in.)
Linearity: ±(1% reading + 0.01 m/s)
±(1% reading + 0.033 ft/s)
Repeatability: ±0.5% of reading @ 25 °C
Accuracy: ±2% of measured value (in reference conditions
where the fl uid is water at ambient temperature, the sensor
is inserted at the correct depth and there is a fully developed
