SERIES H14B
HIGH PRESSURE ARMORED LEVEL GAUGES
Benefits & Features
- Maximum protected level gauges using 34mm wide glass
- Pressures up to 4000 PSIG @ 100°F, Temperatures up to 800°F
- Standard gauges rated up to 300 PSIG @ 421°F Saturated steam
- Standard Gauges with 1/2” FNPT End Connections (in stock)
- Steam Configurated Gauges for over 300 PSIG available in transparent gauges (side connected configurations in stock)
- Optional 3/4” FNPT connections and 1/2” or larger flanged connections available in end, side, or back connected configurations
- Reflex Gauges provide economical level indication using one glass and per chamber/section. The level of the media in the vessel appears black and the prismatic glass reflects back silver where media is not present. Light is only required in the front of the gauge.
- Transparent Gauges utilize two glasses, one on each side of the chamber for direct visual observation of the vessel’s media, level, quality, and color. Light is required from the back.
- Wetted Parts conform to NACE MR0175 & MR0103
- All parts listed in ASTM & ASME B31.3
- Carbon Steel Covers are Shrouded to Protect the Glass Edges
- All Gages feature a one-piece chamber design, regardless of length
Reflex vs Transparent
- Reflex Gauges provide economical level indication using one glass per section. The level of the media in the vessel appears black and the prismatic glass reflects back silver where the liquid is not present. Light is only required in the front of the gauge.
- Transparent Gauges utilize two glasses, one on each side of the chamber for direct visual observation of the vessel’s liquid, level, quality, and color. Light is required from the back.
