The KOBOLD DIH rotating vane flow indicator for liquids offers visual flow indication without flow measurement in a compact design.
Similar to the KOBOLD DRH paddle-wheel flow sensor, but without the electronics, the DIH includes a highly visible, red polypropylene paddle wheel to provide visual indication of flow.
The DIH is available with your choice of nickel-plated brass, stainless steel or POM (polyoxymethylene) housing to suit a variety of liquid flow indication applications.
