Features

• Shatter-Resistant Triple-Scale Flow Tube

  Tubes are made of shatter-resistant polycarbonate resin and can be rotated to position desired scale for easy reading. Scaled for CO2, argon and argon/CO2 mix, and helium.

• Built-in Rupture Disc

  Reduces possibility of flow tube damage due to inadvertent high-pressure surge. Must be replaced if ruptured- not auto-resetting.

• Precision flow-adjustment valve

  Allows easy adjustment to desired setting

• Optional Dual Flowmeter Regulator

  Dual flowmeter regulator has a back-pressure compensated flow tube with shatter-resistant polycarbonate cover. It is repositionable for easy reading and features triple scale for argon, helium and argon/CO2. Features include sensitive needle valve for fine adjustment and a 2-inch (51 mm) gauge.

• True Blue Warranty

  Flowmeter regulators are covered by the Miller True Blue® 3 YR. warranty.

• Extra-Long Flow Tube

  Expanded scales are easy to read and accurate within five percent of full reading. Can be attached to regulators or pipeline installations.

• Unique Self-Centering Ball Guide

  Miller-Smith’s exclusive ball-centering flow tube provides accurate flow readings even if tipped. Others use conventional guide where the ball floats off center causing the actual gas flow to be two times greater than indicated.
