Product Description

The KOBOLD VKM flow meters and switches fill an important gap in the high viscosity media measurement arena. Using KOBOLD’s patented viscosity compensation system, these metal rotameters are essentially insensitive to viscosity and density changes during operation. This development in flow and measurement control technology has resulted in an extremely versatile device suitable for many applications where standard technologies have been inconsistent or otherwise have failed.
