New metal magmeter features easy hot tap installation without system shutdown

February 6, 2007
GF Piping has introduced the new Signet 2552 Metal Magmeter, a rugged insertion flow sensor that permits hot-tap access to the pipe stream. This design allows quick and easy installation or maintenance without system shutdown, significantly reducing overall costs. Three output choices are incorporated into a durable metal housing, providing a robust device capable of accurate flow sensing in extremely harsh environments. The 2552 can be mounted into a broad range of pipe sizes from 2 to 48 inches (DN50 to DN1200). Outstanding performance characteristics include a wide dynamic flow range of 0.15 to 33 ft/s (0.05 to 10 m/s) with repeatability of ±0.5 percent of reading at 25 degrees C. Superior linearity of ±1 percent reading provides excellent performance across a wide range of environments. Corrosion-resistant materials include 316 stainless steel, PVDF and FPM to ensure long service reliability and minimal maintenance. Key to the unit’s design is its adjustable configuration, which allows a hot-tap installation using a ball valve. Installation or service can be completed without any additional tools or disrupting the pipe, and retrofitting is easily accomplished. For special underwater applications, a submersible waterproof cable is available.
