Variable Area Flow Meters and Flow Tubes

Porter's expanded P-Series Variable Area Flow Meter line is an all-new range of flow meters that provides significantly greater application versatility for industrial applications. The expanded P-Series offering enhances our existing rotameter product line in acrylic, glass, and metal tube construction. The new products are designed to accommodate greater flow rates, temperatures and environmental conditions. Porter Variable Area Flow Meters include 65mm and 150mm scale length tube assemblies and are available in either forged body or side-plate construction. Forged body models feature a wrap-around window for full 180° tube visibility, and an attractive forged one-piece black anodized aluminum body. Side-plate constructed models are conveniently interchangeable with competitive designs.
