The Aster Rotameter – 10000–50000 LPH – 65 NB – Online Mounted is built for maximum throughput and long-term durability in high-capacity water flow systems. With a flow range of 10000 to 50000 LPH, this is the largest rotameter in the Aster lineup — ideal for large-scale industrial utilities, municipal water treatment plants, and STP/ETP outlets requiring precision and rugged performance.

This model features a heavy-duty clear polycarbonate body for excellent visibility, a corrosion-resistant SS316 float, and reinforced ABS male-threaded end connections designed for 65 NB BSP pipelines. The unit is vertically mounted with bottom inlet and top outlet configuration, and includes a tamper-proof scale with bold, readable markings. It’s factory-calibrated for water (SG = 1) and capable of handling continuous operation in demanding conditions.

If you need a flow indicator that can manage extremely high discharge volumes with dependable performance, this rotameter delivers unmatched capability.
