The Signet 2537 Flow Sensor is the next generation in fluid measurement technology from the inventor of the original paddlewheel flowmeter. This sensor is an enhancement on what is already an industry standard. It has the added functionality of various output options including flow switch, pulse divider, digital (S3L) or 4 to 20 mA. Additionally, it offers low flow, low power and high resolution and can be configured on-site directly through the built-in user interface.
 

• Digital (S3L) and 4 to 20 mA outputs (Multi-function)
• Allows up to six connections to the Signet 8900 Controller
• Low flow capabilities down to 0.1 m/s (0.3 ft/s)
• Polypropylene or PVDF sensor bodies
• Polypropylene or PVDF retaining nuts
• Installs into pipe sizes DN15 to DN200 (½ to 8 in.)
• Test certificate included for -X0, -X1
• Low power and high resolution options

• Sensor shall be capable of sensing flow in either direction ( bi-directional).
• The paddlewheel insertion flow sensor shall generate an electrical signal proportional flow velocity from a range of 0.3-20 feet per second. 
• 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 insertion in pipes from 0.5 to 8 inches.
• The sensor body materials shall be glass-filled polypropylene (black) or, PVDF (natural). 
• The electrometric seals shall be FPM-Viton® (standard) with optional EPDM or FFPM-Kalrez®. 
• Rotor pins shall be Titanium (standard for PP), Hastelloy-C or PVDF (standard for PVDF), with optional ceramic, Tantalum, or stainless steel. 
• Rotor material shall be black PVDF (standard for PP) or natural PVDF (standard for PVDF) with optional Tefzel® with or without Fluoraloy G ® sleeve.
• Sensor shall have integral mount electronics capable of 4-20 mA or, Digital (S3L)or, Flow switch, or pump pulser output.
• The flow sensor shall be a Georg Fischer Signet model 2537 or equal.
