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 a Tungsten Carbide pin provide exceptional wear resistance.

The Signet 2540 Paddlewheel Flow Sensor 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.

• Operating range: 0.1 to 6 m/s (0.3 to 20 ft/s)
• Field replaceable electronics
• Non-magnetic RF detection
• Standard NPT or ISO process connections
• Hot-tap versions for installation/service without system shutdown
• For pipe sizes up to DN900 (36 in.)
• 7.6 m (25 ft) cable
• Adjustable sensor - one size for entire pipe range

• The paddlewheel insertion flow sensor shall generate an electrical signal proportional flow velocity from a range of 0.3-20 feet per second.
• The output signals shall be an open-collector open collector transistor type with non magnetic RF detection.
• Signal transmission lengths shall be capable of distances up to 1000 feet.
• Sensor shall operate with a power input of 5 - 24 vdc, with a maximum current draw of 10 mA.
• The sensor body and fitting shall be 316 Stainless Steel (1.4401)with a rotor material of CD4MCu stainless steel (1.4517), rotor pin Tungsten Carbide GRP 1 (standard),or Stainless Steel (optional), (2): 316 stainless steel (1.4401) retainers, and (2): Fluoroloy B®/PTFE bearings.
• The sensor shall be inserted at the correct depth and there shall be a fully developed flow profile. Linearity of the output signal shall be ±1% of full range, with a repeatability of ±0.5% of full range.
• The sensor shall not create a pressure drop of >1 psi at any flow rate.
• Two optional sensor lengths shall allow the flow sensor to install into a flow installation fitting. Optional sensor lengths will allow standard or hot tap insertion in pipes from 0.5 to 36 inches.
• The sensor shall have field replaceable electronics.
• The flow sensor shall be a Georg Fischer Signet model 2540 or equal.
