F-550 Acrylic Flow Meter
CALL FOR PRICING AND DELIVERY OPTIONS
The F-550 Acrylic Flow Meter is a precision instrument designed for industrial flow monitoring, blending robust panel-mount construction with clear, glass-like acrylic for easy visibility and long-term reliability. Its annealed, one-piece body delivers exceptional durability and chemical resistance, while a white reflective background and permanent scale allow for fast, accurate readings—even in direct sunlight.
With flow ranges from as low as 0.025 GPM up to 20 GPM, the F-550 is engineered for water treatment, chemical dosing, plating operations, OEM skids, and process control. Bulkhead nuts allow easy installation inside control panels or equipment enclosures, and the optional adjustable flow control (needle valve) provides real-time adjustment without extra fittings.
