F-400 Acrylic Flow Meter
CALL FOR PRICING AND DELIVERY OPTIONS
The F-400N Series Acrylic Flow Meter is engineered for accuracy, chemical resistance, and easy visual monitoring in process systems. Each meter is machined from high-quality annealed acrylic and polished to a clear, glass-like finish for optimal readability. The screen-printed scale with a white back reflector ensures clear, direct readings even in challenging lighting.
Polypropylene adapters reinforced with aluminum rings add strength, while FKM O-rings provide excellent chemical sealing. Standard 316 stainless steel floats and guide rods (select models: PVDF/PTFE floats) deliver reliable, long-term operation. The F-400 is designed for ¼”, ⅜”, and ½” FNPT pipe sizes, and handles up to 150 PSI.
