The basis for the SwissFlow liquid flow sensors is a unique, patented technology. A lightweight rotor is placed in a housing with a special geometry. The radial liquid flow caused by the rotor-housing makes
the rotor float. In this condition there is virtually no mechanical resistance, which ensures a long lifetime, a high accuracy and linearity. The 3 vane rotor interrupts an infrared signal that is generated on the integrated electronics and is converted into a pulse output signal. The materials used are 316 Stainless Steel and Vectra for the rotor; this special plastic has been selected for its excellent chemical and thermal resistance. Application in almost any food and non-food is possible with these materials. The electronics are SMD technology, ensuring low power usage and high reliability.
