GF Signet 515 flow sensor P51530-P0 Paddlewheel Flow Sensor

GF Signet P51530-P0 Paddlewheel Flow Sensor

The GF signet 515 Flow Sensor is a paddle wheel flow sensor known for its:

  • Simple Installation: Easy to set up for quick operation.
  • Reliable Performance: Delivers consistent and accurate flow measurement over time, requiring minimal maintenance.
  • Versatility: Wide flow range (0.3 to 6 m/s) for various applications. Compatible with various pipe sizes (up to DN900) through custom GF Signet fittings (tees, saddles, wallets) for optimal positioning. Offered in multiple materials (PP, PVDF, Tefzel) to suit different liquids.
  • Self-powered Output: Generates its signal, working with battery-operated flow monitors like the GF Signet 8150 Flow Totalizer.
