Krohne DK46 DK47 DK48 DK800 Variable Area Flowmeter Gas Liquid Industrial Process Monitoring

The KROHNE DK46/47/48/800 are rugged all-metal variable area flowmeters for liquids and gases. The smaller DK46/47/48 handle low flows, while DK800 covers higher rates. They provide local visual indication and optional switches or transmitters. These rotameters are used where simple, no-power-required flow measurement is preferred in industrial piping.
