With a temperature range of up to 125°F (51°C) and an accuracy of ±10% FS, it guarantees precise readings. Its wetted materials like styrene acrylonitrile body, SS/black glass/nylon float, and polyurethane valve ensure durability. The flowmeter's pressure limit of 50 psi (3.4 bar) makes it suitable for a wide range of applications. It can be easily connected to rubber or plastic tubing via a 1/4" OD connection.
