Series DTFO Variable-Area Flowmeter for Oil

Brass & 316 SS Body, 2% FS Accuracy

The Series DTFO Variable-Area Flowmeter for Liquids measures oil rates with ±2% of full-scale accuracy at an affordable price. 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
