Rotameter

Rotameters, also known as variable area flowmeters or simply VA flowmeters, are widely used to measure conductive/non-conductive liquids and gases. This series of instruments is famous for its simple but practical mechanical measurement principle, which can realize local display without additional power supply. Rotor measurement technology is widely used and versatile. It is suitable for clean liquids or gases with small flows, especially for application scenarios that do not require high accuracy but focus on cost-effectiveness and compact installation. Since 1921, Cologne has specialized in the development and manufacture of rotameters.
