Series DTFO Variable-Area Flowmeter for Oil ,Brass & 316 SS Body, 2% FS Accuracy

 

DWYER DTFO Variable Area Flowmeter for Liquids measures oil rates with ±2% of full-scale accuracy at an affordable price. DWYER DTFO Variable Area Flowmeter is durable metal construction ensures great reliability and the strength to withstand system pressures of up to 3000 psig (200 bar). Available in 1/4″, 1/2″ and 1″ connections for a wide variety of applications. Comes calibrated for horizontal in line mounting.

 

Product Applications

• Monitoring pressure drop across filters or strainers
• Flow scale based on differential pressure
• Liquid level given pressure differential between bottom and top of tank
• Hydraulic equipment
• Oil & gas equipment
• Heat exchangers
• Backflow prevention

 

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
