The KOBOLD DTK Series pelton wheel flow sensor was designed for the high volume OEM market. The compact pelton wheel design requires no inlet or outlet straight piping runs, allowing the device to be installed in locations where space is at a premium. It employs a very simple design. A nozzle built into the inlet fitting directs flow into an impeller with embedded permanent magnets. Impeller rotation is detected by a Hall effect sensor as liquid flow causes the paddle to rotate. The sensor generates a pulse each time a magnet passes, and the pulse frequency is directly proportional to flow rate. The pelton wheel design provides a very repeatable and linear output. The DTK is supplied as standard with a stainless steel body for use with a wide variety of compatible, water-based liquids. The simple and reliable design of the flow sensor makes it an economical choice for many applications.
