External Float Chamber Water Level Controller & Probe Chamber

About this part

Heavy-duty external float / conductivity probe chamber designed to mount externally on the boiler shell. Isolates delicate level sensing instruments from internal boiler steam turbulence. Provides precision signals for automated boiler feedwater pump sequencing, high-level alarms, low-level alarms, and fail-safe extra-low water burner fuel cutoff to prevent catastrophic boiler dry-firing.

Key features

• Heavy-wall carbon steel / ductile iron pressure vessel rated for high steam pressures
• Equipped with top electrical enclosure for multi-step switching or continuous level transmission
• Side flanged process connections with bottom blowdown drain cock port
• Protects level sensing floats and probes from internal drum surging and boiler foam
• Enables routine daily float testing and chamber blowdown maintenance

Typical applications and wear

Fire tube and water tube package steam boilers. Wear involves sediment/sludge accumulation and microswitch mechanical contact wear.

Compliance

Supports boiler feedwater control and low-water protection; final alarm and cutoff requirements depend on the boiler design and local inspectorate.
