Dwyer Series DTFA Variable-Area Flowmeter for Gases

The Dwyer Series DTFA Variable-Area Flowmeter for Gases measures gas flow rates with ±5% of full-scale accuracy at an affordable price. Rugged aluminium construction ensures great compatibility and the strength to withstand system pressures of up to 3000 psig (200 bar). Available in either 1/4″ or 1/2″ NPT connections. Comes pre-calibrated for horizontal in-line mounting.

Product Applications

  • Monitoring pressure drop across filters or strainers
  • Flow scale based on differential pressure
  • Liquid level is given pressure differential between bottom and top of the tank
  • Hydraulic equipment
  • Oil & gas equipment
  • Heat exchangers
  • Backflow prevention
  • Durable metal construction ensures great reliability and the strength to withstand system pressures of up to 3000 psig (200 bar)
  • Shatter proof construction, unlike glass tube variable area flowmeters, yields long operation life
  • Preform precisely in high temperature, high vibration, shock-prone environments
