Simple to install with time-honored reliable performance, the GF Signet 515 Rotor-X paddle wheel flow sensors are highly repeatable and rugged sensors that offer exceptional value with little or no maintenance. The output signal of the GF Signet 515 Rotor-X paddle wheel flow sensor is a sinusoidal frequency capable of driving a self-powered flow monitor such as the GF Signet 8150 Flow Totalizer.

The GF Signet 515 Rotor-X paddle wheel flow sensors have a wide dynamic flow range of 0.3 to 6m/s (1 to 20 ft/s), which allows the sensor to measure liquid flow rates in full pipes and can be used in low pressure systems.

The GF Signet 515 Rotor-X paddle wheel flow sensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices include PP, PVDF, and Tefzel make this model highly versatile and chemically compatible to many liquid process solutions. GF Signet 515 Rotor-X paddle wheel flow sensors can be installed in up to DN900 (36 in.) pipes using GF 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. GF Signet 515 Rotor-X paddle wheel flow sensors are also offered in configurations for wet-tap and intrinsically safe installation requirements.

Applications for the GF Signet 515 Rotor-X Paddle Wheel Flow Sensor:

  • Filtration Systems
  • Pure Water Production
  • Chemical Production
  • Liquid Delivery Systems
  • Pump Protection
  • Scrubber Systems
  • Water Monitoring
  • Not suitable for gases
