Dwyer DTFA Series Dial Variable-Area Flow Meter for Gases |
Dwyer DTFA Series 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
Application
- 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
