Boiler water level gauge glass systems
Visual Bi-Color Boiler Water Level Gauge
Visual Bi-Color Boiler Water Level Gauge is rated to 3000 psi (207 bar) and produces a red/green image to indicate the water level in a high-pressure steam drum.
With a one-piece trapezoidal shape body, light projected through steam produces a red image. Light projected through water is refracted and produces a green image.
Viewable from three sides, it provides a clear red/green image and offers a 1 year maintenance-free service life. Two discs of premium V-1 quality mica protect the gauge glass from erosion. Belleville washers eliminate hot re-torquing. With nipple connections and center support, it meets the requirements of the ASME Boiler and Pressure Vessel Code.
The standard features of this high-performance gauge reduce maintenance and the total cost of operation. Optional Intrinsic Safety Protection and Explosion Proof Protection are available to meet hazardous area classification requirements.
Reflex Level Gauge Glass
Reflex Level Gauge Glass is rated for 375 psi (530 psi / 24 bar for steam) and provides excellent visibility of liquid level. Light refracting grooves in the glass cause the liquid to appear black and steam to appear white.
The high-contrast window design allows gauges to be stacked on top of one another without concern for misalignment. The heavy-duty cover and body facilitate glass and gasket alignment and also help prevent gasket blowout. Belleville springs maintain gasket loading under thermal and pressure cycles.
Transparent Level Gauge Glass
High Pressure Flat Glass Gauge is rated for 1000 psi (69 bar) and is structurally designed with thicker and wider body to resist deflection and meet ASME Pressure Vessel Code requirements, which no longer permits the use of reflex glass. It provides constant gasket loading under thermal and pressure cycles.
Precision tempered and ground Borosilicate glass provides high strength and clear visibility, while mica shields protect the glass from the effects of corrosion for an extended service life.
