The Heliflu™ TZN flowmeter is designed for high accuracy measurement of liquids from very light LPG products to heavy crude oils. 

The advanced design and robust construction with thousands of available configurations enable the Heliflu™TZN flowmeter to be used in the widest and most demanding applications.

Its engineered rotor offers superior linearity and excellent repeatability making it the obvious choice for custody transfer measurement for more than 40 years.

The HelifluTM flowmeter accurately measures your product! As the liquid hydrocarbons move through the meter, the fluid rotates the helical rotor at a speed directly proportional to its flow rate. 

Each revolution corresponds to a precise volume of liquid. Magnets mounted in the rotor induce electrical pulses in an adjacent pick up coil. These resulting pulse frequency occurs in relation to the flow.

With the Faure Herman helical rotor, fluid velocity is parallel to the blade, making it less sensitive to viscosity and density variation. The rotor is manufactured from one solid block (no welded parts) of either titanium or aluminum. 

This design is based on detailed engineering analysis and increases reliability and performance. 

The helical rotor shape and rounded front edge, combined with light weight material improves stability and linearity even at high viscosity, while reducing wear on bearings. 

Rotors are designed and optimized during in-house calibration to fit the final application requirements.
