Description
In fire-sprinkler systems, early detection of water flow is critical. The LIFECO LF-WFS-450 addresses this: when water flows through a 4″ (100 mm) pipe, the internal vane mechanism detects the movement and triggers an alarm signal via its dual SPDT micro-switches. This helps facility managers and fire-safety engineers monitor system activity, verify valve openings, or detect unintended flows. Unlike generic flow sensors, this model is specifically designed for wet-pipe fire protection systems, with FM/UL approval and a heavy-duty saddle mount that clamps securely onto the branch pipe without full re-routing. Its high pressure rating (up to 450 psi) and rugged construction ensure reliability in demanding industrial or commercial buildings. Whether deployed in a high-rise, manufacturing plant, data centre or institutional facility, the LF-WFS-450 offers peace of mind by ensuring that any significant water flow — such as caused by a sprinkler activation or valve release — does not go unnoticed. Its dedicated design, certification and ease of integration make it superior to generic flow switches not specifically rated for fire-life-safety use.
