HeliflutM TZN

The HELIFLU™ TZN Flowmeter is designed for high accuracy measurement of liquids : from very light LPG
products to heavy crude oil. The advanced design and  robust construction together with a wide range of available options enable the HELIFLUTM TZN Flowmeter to be used in the most severe environmental
& process conditions.


Key Technological Features
• Wide measurement range up to 15:1 turndown ratio,
• Low pressure drop & back pressure,
• Innovative design of helical profile,
• Simple, robust construction,
• Titanium rotor,
• Excellent resistance to corrosion, high pressures & temperature changes,
• Insensitivity to density changes,
• Low sensitivity to viscosity changes,
• Optional designs for low temperature and high wax / contaminants applications

Key Customer Advantages
• Custody transfer accuracy,
• High stability & reliability,
• Low energy consumption,
• Wide range of viscosities,
• Linearity suitable for multi-product measurement,
• Low cost of ownership, Simplified maintenance,
• Long service life : up to 100,000h MTBF,
• Use for dirty crude oil applications,
• Use for master metering calibration.

High Accuracy Flowmeters
