Blue-White Industries F-40250LN-8 Flowmeter 1/2 Inch NPT Female

Blue-White Industries F-40250LN-8 is a compact acrylic flowmeter with a 1/2" female NPT connection, designed for inline, low-flow measurement. It reads 0.025–0.250 GPM (0.1–1.0 LPM) and uses a PVDF float inside an acrylic body, with a calibrated scale to indicate flow rate for the LN-8 variant. This model is part of Blue-White's F-400N acrylic family, and the 1/2" adapter is specified as a 0.50" F/NPT connection. The F-400N line emphasizes accurate measurement in small-diameter lines, making it suitable for compact dosing or monitoring loops in water systems. Note that Blue-White states these meters are calibrated for water and may not be guaranteed for liquids other than water.
