Fire Protection Flow Indicators

UBW’s flow indicators allow users to verify proper water movement through fire protection systems. Our team designs and manufactures high-pressure flow indicators that provide quick, clear visual confirmation. Our Model 70P Flow Indicator supports essential monitoring functions in sprinkler lines, standpipes, and fire department connections (FDCs), helping ensure your system performs as expected when it matters most.

Flow Indicator Applications in Fire Protection

Sprinkler Systems: Flow indicators allow you to verify water flows to the sprinkler heads during testing or active fire conditions. The lack of visible flow offers an immediate warning if there’s a blockage or a closed valve.

Fire Department Connections (FDCs): Install a flow indicator just after the FDC to show whether water from responding fire crews is reaching the system. It provides instant feedback without requiring additional equipment.

Hydrostatic Testing: Flow indicators can visually verify water movement through the system during inspections. This helps confirm that all lines are pressurized and free of obstructions.

Standpipe Systems: In multi-story buildings or large facilities, flow indicators help maintenance teams and fire marshals verify that water reaches remote or elevated sections of the system.

Why Choose the Model 70P Flow Indicator

United Brass Works builds the Model 70P for performance, visibility, and durability in demanding fire protection environments.

Clear Visibility: Each unit includes a polycarbonate viewing window that shows water movement in real-time. Without gauges or meters, you can see flow at a glance.

High-Pressure Performance: The Model 70P is 100% pressure tested and rated for 175 WOG at 150°F. Its male x female design makes installation easy in most system configurations.

Reliable Construction: We use corrosion-resistant materials and precision machining to ensure long-term reliability with minimal maintenance.

Easy Installation: Available in a range of sizes, the Model 70P fits into both new systems and retrofits. The compact body and common connection sizes simplify integration into your layout.
