GF Signet 2537 Paddlewheel Flowmeter

Corrosion resistant insertion magmeter with optional display, accurate measurement even in dirty liquids.

The GF Signet 2537 paddlewheel flow meter represents the latest advancement in fluid measurement technology, building on the legacy of the original paddlewheel design. This upgraded flow meter offers enhanced functionality with multiple output options, including flow switch, multi-functional pulse divider, Digital (S³L), and 4 to 20mA outputs. It excels in low flow conditions, operates with low power, and provides high-resolution measurements, all configurable via its user-friendly built-in interface.

Installation is straightforward, as the GF Signet 2537 uses the same fittings as the widely used GF Signet 515 and 2536 sensors, accommodating pipe sizes from DN15 to DN200 (0.5 to 8 inches). Available in both Polypropylene and PVDF, this versatile flow meter is ideal for a range of applications, including chemical processing, water and wastewater monitoring, and scrubber control systems.
