Swiss Flow

The Swissflow patented technology can be used in many ways and customised for many purposes. Currently, we are manufacturing two specific flow meters for worldwide distribution. You can always contact us for customised implementations. As our customers keep finding creative and new ways to use the technology, we will expand our offerings.

SF800 – LOW PRESSURE FLOW METER:

The patented SF800 is an all purpose flow meter with an excellent price-performance ratio. It is suitable for a wide range of applications and large variety of fluids, and covers flow velocities of 0.5 to 20 liter per minute at temperatures of -20 to +90 °C and an operating pressure of 16 bar (max 40 bar).

The SF800 is entirely made of high-quality plastics and composites with great chemical and thermal resilience. The housing is made of PVDF, a high grade PVC, while the internal rotor of only 0.04 gram is made of Vectra, a liquid crystal polymer of very low weight. Both material are not susceptible to limescale.

An integrated PCB emits the infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse. Because of the construction and geometry of the rotor housing, the Swissflow flow sensors can withstand high pressure.

SF800/6 – HIGH PRESSURE FLOW METER:

The SF800/6 is the high-pressure version of the SF800 with extra metal enclosure. With an operating pressure of 250 bar and burst pressure of 750 bar, it is perfect for more demanding and high stress environments while retaining the versatility and other qualities of the SF800.

The inside of the sensor is similar to the SF800, and is made of high-quality plastics and composites with great chemical and thermal resilience and no susceptibility to limescale.

An integrated PCB emits the infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse. Because of the construction and geometry of the rotor housing, the Swissflow flow sensors can withstand high pressure.

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

Contrary to many other fluid flow measurement systems, Swissflow sensors do not have to be calibrated.

Real World Applications:

Cooling Systems:
The sensors receive excellent results in water-cooled regulating systems by professionals and hobbyists alike…..
Food and Beverage:
Post mixed beverage systems, bar management systems, dosage regulating systems.
