A helical gear flow meter is a type of positive displacement (PD) flow meter. This means it measures flow by repeatedly trapping a known volume of fluid and then releasing it.
High Accuracy: They offer excellent accuracy, especially for high-viscosity fluids.
Good for Viscous Fluids: Their design is particularly well-suited for measuring thick, viscous liquids (like oils, resins, polymers, and glues) that might be difficult for other flow meter types to handle accurately.
