GT130x Series

GT130x Series Glass Tube Variable Area Flow Meters

Efficient and cost-effective for moderate accuracy requirements. Full-View® 1100 Series replacements.

Models 1305 / 1306 / 1307

The GT130x Series glass tube VA flow meters are a family of versatile and economical meters designed for general use in applications with moderate metering accuracy requirements — typical accuracy ranges are 1% to 10% full scale, depending on the model selected. They are ideal for purge type service, seal oil systems, bearing lubrication and cooling water indication, and offer o-ring seal construction with ten-to-one rangeability, as well as a wide range of float types and capacity ranges.

The GT130x Seal Series flow meters provide an excellent and modular drop-in replacement for existing Brooks Instrument Full-View® 1100 Series meters: models 1110, 1114, 1140, 1144.

Features

Broad range of flow ratings from 0.8 to 25 gpm; 3 to 50 scfm
Pressure ratings up to 500 psig / 34 bar
Accuracy ranges from 1% to 10% Full Scale
Calibrated to process conditions with 75mm, 127mm or high resolution 250mm direct reading scales
Sturdy bolted side-plate construction
Standard NPT or flanged connections
Vertical inlets and outlets standard
Glass containment safety sleeve ensures personal safety

Benefits

Cost-effective accuracy combined with long-lasting repeatable measurement
Reliable O-ring seal design for leak-free process connections
Rugged side-plate construction protects glass tube from piping stress and/or vibration
