Krohne DK46 DK47 DK48 DK800 Variable Area Flowmeter Metal Tube Rotameter Industrial Flow Measurement

KROHNE DK46/47/48/800 series are all-metal rotameters (variable area flowmeters) for reliable flow measurement of liquids and gases. They are compact, robust, and require no power for local indication. The DK46/47/48 cover small flow rates, while DK800 handles higher flows. These are popular in applications where glass tube rotameters cannot be used due to pressure or temperature.

• All-metal wetted parts – safe for high pressure/temperature
• Float damping for stable reading
• Optional switches for low/high flow alarm
• Simple installation – no straight run required
• Easy reading via mechanical indicator
• Wide material selection for aggressive media
• Low maintenance – only float movement

• Sizes: DK46/47/48: DN15–DN50; DK800: DN15–DN150
• Flow Range: DK46/47/48: 1–800 l/h (water), 0.02–25 m³/h (air); DK800: up to 180 m³/h (water)
• Accuracy: ±1.6% to ±4% FS
• Max Pressure: 100 bar (DK46/47/48), 40 bar (DK800)
• Max Temperature: +200 °C
• Materials: 1.4404/316L stainless steel, Hastelloy C-22
• Connections: Flanged, threaded, sandwich

• Chemical dosing and injection
• Gas flow in purging systems
• Cooling and lubrication circuits
