Product Description

The DK32/DK34/DK37 are metal tube rotor flow meters designed for low flow rates. These meters can measure liquids, gases, or steam. Due to their robust design, the DK series flow meters are particularly suitable for extreme working and environmental conditions. The meters can be fitted with fine-tuning needle valves, allowing users to easily set and adjust specific flow rates. These meters are widely used in industries such as petrochemicals, oil refining, fertilizers, steel, pharmaceuticals, and more for low flow rate measurement and process control.

In the medium pressure fluctuation is large, in order to make the DK series flow meter to get stable and accurate measurement and flow output, the matching pressure regulator (constant current) should be selected. It ensures that the flow display and measurement are not affected when the medium pressure changes.
