What is Wedge Flow Meter?
A Wedge Flow Meter is a type of differential pressure (DP) flow measurement device used to gauge the flow rate of liquids, gases, or steam in a pipeline. It operates based on the principle of creating a differential pressure across a wedge-shaped restriction in the flow path. The degree of pressure drop across the wedge is proportional to the flow rate.
Arrotop’s Wedge Flowmeters are ideal for industries where precise and dependable flow measurement is critical. These flowmeters feature a unique V-shaped wedge design, which creates a differential pressure that is directly proportional to the flow rate. This design ensures accurate measurements even in applications involving challenging fluid conditions such as high viscosity, suspended solids, and abrasives.
Arrotop’s range of wedge flowmeters offers reliable and accurate flow measurement solutions tailored to meet the demands of various industrial applications. Our models ensure high accuracy, robust construction, and long-term reliability, making them ideal for a wide range of industries.
