KROHNE Variable Area Flowmeters

KROHNE Variable Area Flowmeters provide a simple and cost-effective solution for measuring gases and liquids without the need for auxiliary power. These meters include glass and metal tube purgemeters for low-flow applications below DN15 (½”) and process meters up to DN150 (6”). Optional outputs such as switches, 4–20 mA, HART®, FOUNDATION™ Fieldbus and Profibus-PA ensure smooth integration into various systems. Designed for global industrial use, the range is approved for hazardous areas and supports SIL 2 safety applications.

Variable area flowmeters, also known as rotameters, are widely used for measuring the volumetric flow rate of both conductive and non-conductive media. Their reliable mechanical operating principle makes them ideal for low-flow measurement where cost-effectiveness and compact installation are priorities. With a manufacturing legacy dating back to 1921, KROHNE has built strong expertise in VA flow measurement.
