Working Principle Helical flow meter
At its core, the helical rotor flow meter operates by displacing a fixed volume of fluid through its rotor mechanism. The helical shaped rotors, which are positioned inside the meter, create a swirling effect as fluid enters and is measured. As the fluid flows, the movement of the rotors generates a consistent torque, enabling accurate volume displacement measurement. This ensures precise flow rates for liquids, making it ideal for diverse applications. Its rotor positive displacement capabilities make it a valid choice for industries seeking reliable and accurate flow measurement solutions.
