Krohne UFC400 CG35011100 Ultrasonic Flow Signal Converter

The Krohne UFC400 CG35011100 is a four-wire ultrasonic flow signal converter, designed to match OPTISONIC 3000 and OPTISONIC 4000 series ultrasonic flow sensors. It processes ultrasonic echo signals and calculates bidirectional liquid flow parameters to form a complete inline ultrasonic flow measurement system.

This converter supports multiple analog and digital communication interfaces and complies with NAMUR NE107 diagnostic standards. It features a field-proof housing with local display, delivers stable measurement for conductive and non-conductive liquids, and is widely used for system maintenance and spare part replacement in process industries.
