Armored Level Gages

Standard construction includes a solid one-piece chamber machined from bar, bar stock covers, tempered glass, steel bolts and nuts. Available in carbon steel (A696 C) or stainless steel (A511 316LSS) chambers. Full ANSI 300# pressure class rating to 600°F. Replaces the older Series 12 and Series 5 gages.

→ Low-to-medium pressure applications; replaces Series 12 / Series 5

Designed to give accurate liquid level readings of liquids that have a tendency to surge or boil. Highly effective in reducing boiling effects of entrained gas released under lowered pressure, liquid vaporization at critical low pressure, and boiling caused by temperatures exceeding the boiling point. Non-frosting unit available for liquids with unusually low boiling points.

→ For boiling or surging liquids; non-frosting unit available

One-piece chamber machined from bar, forged steel covers, tempered glass, alloy steel bolts and nuts. Select reflex (prismatic) or transparent (clear) glass. Recessed gasket seats aid in positioning and retaining the gasket. Available in carbon steel, low temperature carbon steel (A350 LF2), and 316LSS. FM Approved.

→ FM Approved — medium-high pressure applications

Solid one-piece chamber machined from bar, steel covers, tempered glass, alloy steel bolts and nuts. Features mid-span supports (tie-bars) for increased pressure ratings — recessed so there is no blind spot in the vision. Recessed gasket seats prevent gasket movement. ABS Certified. NACE MR0175 & MR0103 compliant.

→ High pressure applications; ABS Certified

Heavy-duty high pressure gages available in both reflex and transparent types. Reflex gages assembled with a single plain glass for greater strength. One-piece liquid chamber machined from solid bar steel. Interchangeable sectional gage covers and glasses locked over the liquid chamber with special bolts and nuts. Recessed gasket seats provide a positively leakproof seal.

→ Heavy-duty high pressure applications

The Series 51 is a specially designed high pressure liquid level gage capable of withstanding pressures to 10,000 PSI. The one-piece chamber is machined from solid bar stock carbon steel or stainless steel, drilled lengthwise and crosswise at each port with tie-bars left in between to resist deflection under pressure. Viton® O-rings seal each port and are seated in recessed circular channels to assure proper seating. Available in transparent glass only. Conforms to BS3463, JIS B8211, and DIN 7081.
