Dwyer Series DR Direct Reading Glass Flow Meters

 Flow includes Flow Transmitters, Flow Sensors, Flow meters, Sight Flow Indicators and Water Meters. Mass Flow meters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flow meters indicate flow rate.



The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flow meters have a variety of applications.

Tapered bore in-line indicators for flow rate. Ideal for high purity or corrosive liquid applications, gas and liquid applications, air samplers and medical applications. Flow meters are shipped assembled and ready for panel mounting.

The Series DR Direct Read Variable Area Glass Flow Meters are ideal for the direct flow measurement of air, water, and other commonly used gases. These flow meters 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. Flow meters are shipped completely assembled and include standard panel mounting hardware for quick installation.

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

Application

  • 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
