534FTB Series In-Line Flow Meter

Brand: Kurz Instruments

The Series 534FTB is designed with built-in inlet and outlet piping reducers/expanders to produce exceptional immunity to upstream and downstream flow disturbances caused by elbows, valves, and line size changes. The patented technology results in output with exceptional low end-to-end pressure drop and fast response to velocity and temperature changes.
Features
  • Built-in flow conditioners to accommodate upstream and downstream flow disturbances
  • Ideal for process and specialty gases
  • Exceptional low end-to-end pressure drop.
  • Very low flow noise
  • Sensors resistant to dirt and corrosion
  • Wide turndown capability
  • Zero velocity as a valid data point
