Warrick 192562 Flow Switch

The Warrick 192562 Flow Switch is a heavy-duty, inline Gems FS-380 series piston flow switch built for high-pressure industrial fluid monitoring. Designed with a preset 0.25 GPM flow rate actuation point, this unit features a rugged brass housing and a 1/2 inch NPT male connection, making it a standard for contractors maintaining industrial cleaning equipment and semiconductor cooling loops. The internal magnetic PPS composite piston design provides superior resistance to clogging compared to traditional paddle switches, though a 100-micron filtration system is required upstream to ensure long-term reliability of the SPST, 20 VA reed switch.

Engineered to handle operating pressures up to 1500 PSI and temperatures ranging from -20°F to +275°F, the FS-380 is the preferred choice for x-ray tube cooling, laser heads, and high-speed spindles. Its fixed set point eliminates the risk of field tampering, while the 24-inch polymeric leads simplify integration into your control panel. For technical accuracy during installation, ensure ten diameters of straight pipe run both upstream and downstream and use a suitable thread sealant to maintain a leak-free 1/2" NPT interface.

• Clog-Resistant Design: The one-piece PPS composite piston and 316 stainless steel spring minimize internal friction and debris accumulation.
• High-Pressure Tolerance: Rated for line pressures up to 1500 PSI (107 bar), ideal for high-pressure wash systems and hydraulic monitoring.
• Reliable Switching: Features a hermetically sealed SPST 20VA reed switch (Normally Open at no flow) for consistent signaling to PLCs or alarms.
• Compact Footprint: Inline 1/2" NPT configuration allows for easy retrofitting into tight mechanical skids and cooling manifolds.

• What is the proper mounting orientation for this switch? While the FS-380 can be mounted in various positions, the 0.25 GPM set point is calibrated in a vertical position with the inlet port down. Horizontal mounting may cause slight variations in actuation accuracy.
• How do I prevent false triggers or sticking? Always verify that 100-micron filtration is installed before the switch. Debris smaller than the piston clearance can cause mechanical hang-ups or erratic signals.
• Can this switch handle corrosive fluids? This model uses brass and fluorocarbon O-rings; always cross-reference your specific medium with a chemical compatibility chart for these wetted materials before installation.
