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
