Vetrix VA Series – Variable Area Flow Meter is used to measure the flow of liquids or gases within pipelines. It consists of a vertical tube where the fluid passes through, with a diameter that gradually enlarges from bottom to top. Inside the tube, there is a float that moves vertically and adjusts its position based on the flow rate. As flow increases, the float ascends until the forces from fluid resistance and buoyancy reach equilibrium, establishing a fixed position that remains consistent regardless of the flow rate. The flow rate can be determined by reading the scale aligned with the float’s position.
