Paddlewheel Flow Switch – FLS F3.05
The FLS F3.05 is a simple and reliable insertion paddlewheel flow switch designed to safeguard pumps from running dry or operating against a closed valve. It features a mechanical SPST contact that activates when flow velocity falls below the factory preset threshold of 0.15 m/s (0.5 ft/s). A built-in LED indicator provides a clear local display of flow status.
A specially designed range of fittings allows fast and easy installation on all pipe materials, covering sizes from DN15 to DN600 (0.5” to 24”).
