Description

Series DR Direct Reading Glass Flowmeters

65 mm and 150 mm, Interchangeable Flowtubes, Direct Reading Scales

The Series DR Direct Read Variable Area Glass Flowmeters are ideal for the direct flow measurement of air, water, and other commonly used gases. These flowmeters are designed with direct read scales with no need for correlation charts. They feature borosilicate glass tubes in 150 mm or 65 mm scales with aluminum and SS metering valve options.

Flowmeters are shipped completely assembled and include standard panel mounting hardware for quick installation.

 

Product Applications

  • Film processing
  • Paper manufacturing
  • Chemical processing
  • Semiconductor industry
  • Water and air pollution analysis equipment
  • Metals processing
  • Industrial fuel and energy conservation
  • Cylinder gas metering
  • General laboratory and industrial applications

 

 

Features

  • Permanently fused ceramic scale with vertical locator line, reflective lens background and 1.5 X magnification lens reduces parallax and eye fatigue saving time
  • Long operating life with thick polycarbonate front shield that protects tube from breakage and serves as a magnifying lens to enhance reading resolution
  • Optional needle valve for flow rate control eliminating the need for a separate valve reducing cost
  • Increased protection with included safety blow-out back panel for added safety
