Overview

The VA40 is a glass tube variable area (VA) flowmeter for flow measurement of liquids and gases. The all-purpose flowmeter is suitable for all basic applications up to +100°C / +212°F and max. 10 bar / 145 psi. Typical applications include flow measurement of flushing, purging or inert gases or heating and cooling circuits.

  • Simple, low-cost measuring principle without auxiliary power
  • For direct reading of the flow and observation of the medium
  • Optional MIN/MAX flow switches (SIL 2 conform acc. to IEC 61508-2) or 4…20mA for recording and control
  • Full scale value for liquids: 0.4…10,000 l/h / 0.1…2,650 GPH
  • Full scale value for gases: 7…310,000 l/h / 0.25…11,000 SCFH
  • Uncertainty: ±1.0% (acc. to VDI/VDE 3513, sheet 2)
  • Turndown ratio 10:1
  • Use in hazardous areas
  • SIL 2 conform for Safety Instrumented Systems (SIS)
  • Available as food and pharmaceutical variant (with FDA compliant materials)
