Benefits & Features

Maximum protected level gauges using 34mm wide glass
Pressures up to 3270 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.

Notes:
Saturated steam applications above 300 PSIG @ 421°F require Mica Shields and upgraded Graphite gaskets.
Adding graphite gaskets and mica shields can extend the life of the glass in all steam applications.
Flanged connections on gauge or valves will derate the entire gauge when rated lower than the gauge.
