OVERVIEW
The Arrotop Eccentric Orifice Plate (Model: ARO-EP-002) provides reliable and precise flow measurement for pipelines handling fluids with particulates or high viscosity. Its eccentric bore design, where the center of the orifice is offset from the pipe axis, allows particles and condensation to flow freely, reducing the risk of clogging and maintaining accurate measurements. This makes the ARO-EP-002 ideal for challenging applications in industries such as chemical processing, oil and gas, and water treatment. Constructed from high-quality materials, it is available in various sizes and can be customized with specialized coatings to meet specific operational requirements, ensuring durability and long-term performance.
