Series Q20 Gauge Features & Specifications

Lengths

Series Q20 gauges are available in nine standard visible glass lengths. Multiples of the same size windows (up to nine sections) in a single piece bar stock liquid chamber are used for longer lengths.

Connections

Standard Series Q20 Gauges are furnished with ½” or ¾” inch NPT female end connections. Other connections available: ½” or ¾” NPT female or male, side or back, flanged ends, side or back to suit mating connections.

Liquid Chambers

Chambers are machined from bar stock with recessed gasket seats. Bridges are also machined to maintain pressure and strength.

 Covers

All covers are manufactured to be interchangeable.

Bolt & Nuts

 Alloy steel to ASTM Standards.

 Glass

The tempered glass must be protected from corrosive substances such as caustic acid and hydrofluoric acid. Only transparent glass with mica or Kel-fshields must be used in these applications. The Tempered Borosilicate Glass conforms to BS3463, JIS B8211, DIN 7080 & DIN 7081.

 Gaskets

Precision die cut from the highest quality materials.

Protection

 All carbon steel parts are coated both externally and internally with a high quality rust inhibitor. This coating serves as a superior bonding base for paint. It is recommended that all Q20 Gauges be installed with Quality Gauge Valves, having safety ball checks, which help provide protection against physical injury and loss of product should glass breakage occur.

Materials

Standard chamber materials include Carbon Steel (A696 C), Low Temperature Carbon Steel (A350 LF2) and 316LSS (A511 Dual Rated for 316SS & 316LSS). Wetted Parts Conform to NACE MR-01-75. All Parts are ASTM Grade and listed in ANSI 31.3
