Blue-White Industries, Inc. F-55200L Flow Meter

The Blue-White F-55200L Flow Meter is a panel-mount rotameter designed for precise water-flow monitoring in pressurized systems. It features a one-piece cast acrylic body with a 4 inch (100 mm) scale for direct reading and a flow range of 2.0 to 20.0 GPM (7.5 to 75 LPM), read through a 316 stainless steel float. This model uses 1 inch male NPT inlet and outlet connections, polypropylene fittings, and FKM O-rings for chemical compatibility, with a white back reflector to enhance readability in bright environments. An optional flow-control valve is available for fine-tuning flow in selected installations, and common applications include panel-mounted flow monitoring in water-treatment lines, cooling loops, filtration skids, and other high-visibility process or laboratory systems that require a compact, robust indicator of liquid throughput.
