DF – Paddle Flow Sensor With Frequency Output

The KOBOLD DF paddle-wheel flow sensor offers the variety of six material combinations, allowing the DF to be used with compatible water-based, low-viscosity liquids and many aggressive water-based chemicals. This flow sensor employs permanent magnets embedded within a rotating paddle wheel. A Hall-Effect sensor detects the frequency of the magnet passing and provides an output which is directly proportional to the flow rate. The DF is supplied as standard with an NPN pulse frequency output. The compact size, variety of material combinations and economical price make it the perfect flow sensor for many industrial and OEM applications.
