The ABB DA is a compact, low-capacity variable-area (float-type) flow meter constructed entirely from corrosion-resistant plastic materials. Engineered for monitoring liquid or gas purge flows, it features a vertical mount, clear scale, and optional needle valve for precise adjustment. Ideal for purge lines, instrumentation bleed-off, or level/gas flow control in chemical and process systems.
