Type 2540 Stainless Steel
Hot Tap

The Signet 2540 Paddlewheel flow sensor offers the strength and corrosion resistance of stainless steel for liquid applications with low velocity measurements. Unique internal circuitry eliminates the need for magnets in the process fluid, enabling flow measurement of 0.1 to 6 m/s (0.3 to 20 ft/s) while maintaining the advantages of insertion sensor design. Ultraflon 500C bearings and Tungsten Carbide pin provide exceptional wear resistance.

The Signet 2540 offers field replaceable electronics and transient voltage suppression (TVS) to provide greater immunity to large voltage disturbances (i.e. lightning) sometimes encountered in field wiring. Sensors can be installed in DN40 to DN600 (1½ to 24 in.) pipes using the 1½ inch NPT or ISO 7/1-R 1.5 threaded process connection. The sensors are also offered in a hot-tap configuration with a bleed valve service without process shutdown in pipes up to DN900 (36 in.). Both styles of sensors must be used in full pipes and can be used in low pressure systems.


Flow:
  • Installs into pipe sizes: DN40 to DN 900, 1.5 in. to 36 in.
  • Operating range: 0.1 to 6 m/s, 0.3 to 20 ft/s

  • Max Pressure rating: 17 bar @ 100 °C, 250 psi @ 212 °F Optional EPDM: 17 bar @ 82 °C, 250 psi @ 180 °F

  • Power source: 5 to 24V DC, 1.5mA max
  • Compatibility: 8900, 9900, 9900-1BC, 9950
  • *Recommended 198 820 008 (3-1500.663) Hot Tap installation tool (sold separately)
