MEISTER flow switch RVO/U-2/1 supplied by Shanghai Weiteri

MEISTER is a professional manufacturer of flow measurement and control equipment in Germany. Its flow switches are mainly mechanical float/piston structures, which do not require a power supply (pure mechanical contacts), have strong resistance to electromagnetic interference, high voltage resistance, and can be customized with ATEX explosion-proof, high temperature, and food grade materials; Covering the entire scene of liquids (water, oil, coolant) and gases (compressed air), it is widely used in industrial fields such as machine tools, hydraulics, cooling, lubrication, and chemical engineering.

The RVO/U series is MEISTER's classic liquid visualization float type flow switch/indicator, which integrates real-time flow visualization and switch quantity alarm. It has a pure mechanical structure and does not require power supply. It is the mainstream monitoring solution for industrial cooling, lubrication, and hydraulic circuits.

Measurement principle: Vertical cone tube+magnetic float, flow drives float to rise, built-in magnetic core triggers external reed switch contact to output switch signal; Transparent
