Series DTFW Variable-Area Flowmeter

Brand: Dwyer Instruments, LLC

The Series DTFW Variable-Area Flowmeter for Liquids measures water flow rates with ± 2% of full-scale accuracy at a competitive price. 

Durable metal construction ensures great compatibility and the strength to withstand system pressures of up to 3000 psig (200 bar). 1/4", 1/2" and 1" connections are available, with construction choices of a high quality brass or stainless steel.

Comes pre-calibrated for horizontal in-line mounting.
Features
  • 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
