Patented Advanced Adaptative Technology

The revolutionary SwissFlow frictionless fluid metering technology is patented and cannot be sourced from other vendors. The central design feature is a small lightweight rotor that is fitted unattached in a cylindrical housing.

Flow formers at the inlet of the cylinder generate a controlled and constant swirl that causes the rotor to float in the flow stream of the metered fluid. This free rotation is almost without friction and proportionate to the fluid throughput.

The rotation interrupts an infrared signal that provides a direct pulse output. The infrared beam is generated by a diode and detected by a phototransistor on integrated electronics.

The electronics are welded in between the rotor housing and an outer housing, isolating them from external infrared distortions.

This simple but robust design creates unique flow sensors with an excellent price-performance ratio, which have proven themselves in a large number of applications as highly accurate, versatile and durable.

• Accurate: the turbine floats freely in the metered fluid, so no distortion from friction and high linearity. Swissflow sensors do not have to be calibrated
• Versatile: the sensor is suitable for a large variety of liquids and applications and can be installed in any angle or position
• Durable: there is no wear and tear from internal friction and the high grade composite material is not affected by limescale
