GF Signet Flow Sensors
Signet 515 Rotor-X Paddlewheel Flow Sensors
Description:
Operating range 0.3 to 6 m/s (1 to 20 ft/s), Wide turndown ratio of 20:1, Installs into pipe sizes DN15 to DN900 (½ to 36 in.), Highly repeatable output
Product Overview :
The Model 515 GF Signet Flow Sensorssensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices, including PP and PVDF, make this model highly versatile and chemically-compatible to many liquid process solutions. Signet Flow Sensors can be installed in up to DN900 (36 in.) pipes using Signet's comprehensive line of custom fittings. These custom fittings, which include tees, saddles, and weldolets, set the sensor to the proper insertion depth into the process flow. The Signet Flow Sensors are also offered in configurations for wet-tap requirements.
