Kobold DIG - Rotating Vane Flow Indicator

The KOBOLD DIG rotating vane flow indicator offers reliable visual confirmation of liquid flow with its vibrant paddle wheel that spins behind a transparent polysulfone cover, providing operators with immediate status verification without electronic components. Available in brass, stainless steel, or polypropylene housing options, this versatile device accommodates various chemical compatibility requirements while handling flow ranges from 0.13 GPM to 21 GPM of water-based fluids. With five connection sizes ranging from 1/8" to 1" NPT, the DIG series integrates seamlessly into diverse piping systems while maintaining pressure ratings up to 230 PSI (100 PSI for polypropylene models) and temperature capabilities up to 176°F. The robust design features a ceramic axle for extended service life and minimal maintenance requirements, while introducing only 14.5 PSI pressure drop at maximum flow rates to preserve system efficiency. Ideal for applications requiring continuous visual confirmation of process flow without electrical power or complex instrumentation, the DIG combines simple operation with durable construction to deliver reliable performance across a wide range of industrial liquid monitoring applications.
