Signet Magmeter Flow Sensor

The Signet 2552 Magmeter Flow Sensor is a heavy duty, high performance sensor in an adjustable-insertion configuration that can be used with a ball valve for hot-tap installations. This insertion style flow sensor has no moving parts and is constructed of corrosion-resistant materials to provide long-term reliability with minimal maintenance costs.

The 2552 is versatile and simple-to-install, delivering reliable flow measurement over a wide dynamic range in pipe sizes ranging from 2 to 48 inches. Signet 2552 Magmeters offer a variety of output options compatible with Signet flow instrumentation that feature a frequency or digital (S3L) input. The blind transmitter (4 to 20 mA output) or digital sensor interface is available for long distance signal transmission. The empty pipe detection features a zero flow output when the electrodes are not completely wetted. The frequency output is bi-directional while the 4 to 20 mA output can be set for uni- or bi-directional flow

Flow Control's  2007 Innovation Awards Winners

GF Piping Systems’ patented (U.S. Patent No. 7,055,396 BI) technology is the most innovative part of this design. The patent calls out a molding technique for manufacturing the two metal electrodes into the plastic nosepiece at a fixed distance. This allows manufacturing of a high-quality product in a repeatable manner. The patented manufacturing technique is responsible for the product’s outstanding performance characteristics, including reliable repeatability of +/-0.5 percent of reading at 25 C and superior linearity of +/-1 percent plus 0.01 m/s of reading. These characteristics mean excellent performance, even in extreme conditions of 77 F at 300 PSI. Because of this patented, reliable manufacturing technique, all sensors ship with a flow certificate stating that they have been tested in an NIST-traceable flow loop.

what the voters said:
The 2552 magmeter is very reliable and allowed hot-tap installation without system shutdown. In addition, the pcb is potted inside the sensor to avoid humidity. Hot-tap feature, ease-of-use, and minimal tooling to install.
