Signet 2552 Metal Magmeter Flow Sensors

Features

• NIST test certiﬁ cate included

• Award winning hot-tap magnetic ﬂ ow sensor up to DN2550 (102 in.)

• Patented Magmeter technology*

• Operating range 0.05 to 10 m/s (0.15 to 33 ft/s)

• Reliable operation in harsh environments

• Repeatable: ±0.5% of reading @ 25 °C

• Three output options: 4 to 20 mA, Frequency/

Digital (S3L)

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). Two 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 externally powered Signet ﬂ ow instrument, while the digital (S3L) output enables multi-channel compatibility with Signet 8900 or 9900 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 Conﬁ guration Tool is available to customize every performance feature in the 2552 so it can be adapted to the user’s application requirements.

Sensor Selection Guide

The 2552 Magmeter can be installed into a variety of pipe sizes. Follow the steps below to ensure that you choose the right sensor for your application.

Step 1: Determine how the sensor will be installed

A. For standard (non Hot-Tap) installations:

The height of the weldolet (threadolet) and pipe adapter(s) should be determined before the sensor is purchased.

• For retroﬁ t installations, the stack height, or “A” dimension (see Fig. 1), is the overall height from the top of the pipe to the highest point of the stack.

• Sensor tip must be positioned at 10% of pipe ID

• For new installations, Signet recommends a weldolet (threadolet) and an adapter to accommodate the 1¼ in. (or 1½ in. for 2552-3) sensor process threads. The stack height, or “A” dimension (see Fig. 1), is the overall height from the top of the pipe to the highest point of the stack before the sensor is connected

B. For Hot-Tap installations:

The stack height of the ball valve, nipple weldolet (threadolet) and pipe adapters should be determined before the sensor is purchased.

• For retroﬁ t installations, the ball valve must be at least a 1¼ in. (or 1½ in. for 2552-3) valve. The stack height, or “A” dimension (see Fig. 2), is the overall height from the top of the pipe to the top of the ball valve.

• Sensor tip base must be positioned at 10% of

• For new installations, Signet recommends a 1¼ in. or 1½ in. full port ball valve, a short nipple and a weldolet (threadolet). The stack height or “A” dimension (see Fig. 2) is the overall height from the top of the pipe to the top of the ball valve before the sensor is connected.

Step 2: Determine how the sensor will be installed

Once the “A” dimension is determined, go to the sensor selection table and ﬁ nd your “A” dimension on the left column. Next, ﬁ nd the appropriate pipe size at the top of the chart. To determine the correct sensor size locate where the pipe size column meets the max “A” dimension row.

Step 3: Refer to Ordering Information to select corresponding part numbers

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.

Application Tips

• Minimum process liquid conductivity requirement is 20 μS/cm.

• 1½ x 1¼ inch and 2 x 1¼ inch (2552-2 only) retroﬁ t adapters are available for replacement installations of Signet 2552 and 2540 sensors.

3) See Sensor Selection Guide on previous page to determine the sensor length required.
