Durable Flow Switch Designed for Emergency Fire Systems

Durable Flow Switch Designed for Emergency Fire Systems Product Overview Manufactured by Shanxi Bote, this durable flow switch is specially developed for fire sprinkler and fire hydrant valve water supply systems, responsible for real-time flow monitoring inside main fire pipelines. It covers multiple standard sizes ranging from DN50 to DN200, with corrosion-resistant aluminum alloy housing and high-protection internal sensing components that fully comply with fire protection codes and hold official 3C certification, supporting a rated working pressure of 1.6MPa. The unit transmits switch signals by sensing flow velocity changes inside pipes. When pipeline leakage, open sprinklers or water discharge reaches the preset flow value, it instantly sends alarm signals to the fire control room to activate pressure stabilizing pumps and main fire pumps, preventing insufficient water pressure that hinders fire suppression. It works in coordination with fire extinguisher, fire hose, smoke dete…
