SAFETY INSTRUCTIONS

1. Depressurize and vent systems without Hot-tap valve prior to installation or removal.

2. Conﬁ rm chemical compatibility before use.

3. Do not exceed maximum temperature/pressure speciﬁ cations.

4. Wear safety goggles or face shield during installation/service.

5. Do not disassemble or alter product construction.

6. Disconnect power before attempting any service or wiring.

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

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

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.)
