ABB 10A2235 Variable Area Flow Meter 1/2 Inch

ABB's 10A2235 Ratosight Variable Area Flow Meter is a glass-tube rotameter that provides direct, visual indication of flow for clean liquids and gases. Part of ABB's VA Master Flowmeter family, it covers tube sizes from 1/2 inch to 2 inches, with the 1/2" bore used for compact installations, and can be mounted vertically, inline, on a wall, or on the back of a panel. The meter reads a flow rate by a float in a transparent glass tube and can be paired with magnetic switches or relays for automated control. An optional Ratolarm extension (10A2235-OA) adds alarm/limit functionality. The design emphasizes easy range changes and cleaning without removing the device from the line, and ABB highlights rugged performance under mechanical and thermal stress. Common applications include monitoring lubricant flow to protect bearings, cooling-water or other process streams, or flow into and out of tanks or ovens, where immediate visual confirmation of flow is valuable. The 10A2235 family is known for straightforward installation and robust operation in demanding environments, including marine and desalination contexts.
