VKG - Viscosity-Compensating Flow Meter and Switch
Brand: KOBOLD Instruments, IncThe KOBOLD VKG series viscosity-compensating flow meters and flow switches fill an important gap in the high viscosity media measurement field. 
Using KOBOLD’s patented viscosity-compensation system, these metal rotameters and flow switches are largely insensitive to viscosity and density changes during operation. 
This development in flow and measurement control technology has resulted in an extremely versatile viscosity-compensated flow meter and flow switch suitable for many viscous-media applications.
